M/T Tire and Wheel Warranty1. Mickey Thompson Standard Limited Warranty
This warranty applies to the original purchaser of a Mickey Thompson passenger or light truck tire and is not transferable. Eligible tires must be purchased new and must be used on the vehicle which they were originally installed. Additionally, they must be an equivalent or greater load index to that specified by the vehicle manufacturer. For warranty exclusions, please refer to the complete “Mickey Thompson Passenger and Light Truck Tire Limited Warranty” by CLICKING HERE or contact Mickey Thompson’s technical support department at 1-800-222-9092.
If your Mickey Thompson branded tire becomes unserviceable as a result of an eligible adjustable condition during the first 2/32″ of tread wear, it will be replaced with an equivalent new Mickey Thompson tire, FREE OF CHARGE. When the tread is worn more than 2/32″, if the product exhibits an eligible adjustable condition, it will be replaced on a pro rated basis. For the tire pro ration schedule, please refer to the complete “Mickey Thompson Passenger and Light Truck Limited Warranty” at www.mickeythompsontires.com or contact Mickey Thompson’s technical support department at 1-800-222-9092. You must present proof of purchase and be the original owner when requesting a replacement for your tire.
A replacement charge may be required in order to obtain a replacement tire. The replacement charge will be determined by multiplying the dealer’s current selling price by the percentage of original tread depth worn from the tire. You must pay for mounting, balancing, and any other additional charges, such as taxes or the acceptance of a higher priced replacement tire.
Any Mickey Thompson tire that does not deliver satisfactory service due to a balance, out of round or a ride complaint issue will be replaced without charge within the first 2/32nds of the tire’s tread life. After the first 2/32nds the tire is not warrantable for the aforementioned conditions.
When the tread becomes worn to 2/32″ (1.6mm) anywhere on the tire (shown by tread wear indicators molded into the tread grooves), the tire is worn out. WARNING-for important safety information, you must read the section titled “Tire Service Life” and Important Tire Safety and Fitment Information Warnings section of this guide. Additional Tire Safety Information is also available at www.mickeythompsontires.com or from your local dealer.
HOW TO OBTAIN AN ADJUSTMENT
Tire adjustments must be presented to the dealer which originally sold the tire. You must be able to provide proof of purchase and be the original owner when requesting a replacement for your tire. See “Where to Go for Warranty Replacement”.
NO ROAD HAZARD COVERAGE
Many dealers sell or provide their own warranty coverage for road hazards and/or repairs. Mickey Thompson does not provide this coverage. Check with your dealer to determine if Road Hazard/Repair coverage is available from them.
If you receive a replacement tire under the terms of this Warranty, the replacement tire will be covered by the Warranty then currently given by Mickey Thompson for the replacement tire.

2. Important Tire Safety And Fitment Information
|IMPORTANT TIRE SAFETY AND FITMENT INFORMATION|
Mickey Thompson Tires recommends that all vehicle owners and users (called “users”) understand and adhere to the tire safety and fitment warnings, recommendations, guidelines, and instructions (“tire safety and fitment information”) (i) provided by the original equipment (OE) vehicle manufacturer, and (ii) available within the transportation industry and from the government. Specifically, before installing any tires on a vehicle, the user should refer to and obtain an understanding of the tire safety and fitment information available (i) in the vehicle’s owners manual and related materials provided with the vehicle, and that can otherwise be obtained from the OE vehicle manufacturer; (ii) the Rubber Manufacturers Association (www.rma.org), and (iii) the National Highway Traffic Safety Administration (www.nhtsa.gov).
As more fully explained in the tire safety and fitment information, failure to follow the tire safety and fitment information may adversely affect the vehicle’s and/or tire’s performance capabilities, including but not limited to the vehicle’s handling/stability capabilities, and could result in tire failure (including tread/belt separation or blowout). The user must explain the intended service for the vehicle to the local installer/dealer, and the local dealer and installer of the vehicle’s tires are responsible for providing the tire safety information to the user, including the potential risks associated with not following the tire safety and fitment information.
Before installing any tires on the vehicle, the user must (i) review, discuss, and obtain an understanding of the tire safety and fitment information with their local installer/dealer, including the potential risks associated with not following the tire safety and fitment information; and (ii) have a local vehicle service professional inspect the vehicle (including any aftermarket modifications) to advise as to any potential risks associated with installing the tires desired by the user on the vehicle. If, after doing so and considering this information, the user chooses to assume any potential risk and install a non-OE replacement tire on their vehicle (particularly when the user has chosen to install an aftermarket suspension on the vehicle which differs from the OE suspension), the fitment of the tire requires, at a minimum, all of the following special considerations are met:

General Tech Bulletins1. Understanding The Service Life Of Your M/T Tires
|UNDERSTANDING THE SERVICE LIFE OF YOUR M/T TIRES|
DETERMINING THE AGE OF A TIRE
The manufacturing date of a tire is incorporated into an 11 digit code, called a TIN (Tire Identification Number) located down by the bead of the tire. The only exception would be most Pro Drag Radials, which do not incorporate traditional TIN’s. On street legal tires, the TIN is preceded by the letters “DOT”.
The last four numbers of the TIN represent the week and year of manufacture. In the Example below, this tire was produced the 35th week of 2017.
EXAMPLE: CY1JM5FJ3517 (3517 = date code)
THE SERVICE LIFE OF YOUR M/T TIRES IS NOT ENTIRELY DICTATED BY CHRONOLOGICAL AGE.
All M/T tires are designed with conscience efforts to maximize tire life with maximum performance. That being said, the useful life of a tire is a function of its use, application, and storage conditions. Since these elements can vary widely, and are not controlled by the manufacturer, accurately predicting the life of any specific tire based on calendar age is near impossible.
However, with that understanding Mickey Thompson does recognize the benefit of a uniform approach regarding the service life issue. Accordingly, M/T has come up with the following age criteria for removing tires from service. These dates are based from the manufacturing date.
Under no circumstances should these recommendations be consider as an “expected” service life. Most tires will need to be replaced before these time limits are met due to service conditions.
Tires can be removed for several reasons, such as:
TIPS FOR MAXIMIZIING THE LIFE OF YOUR M/T TIRES.

2. Understanding DOT Tire Inflation Pressures and Load Capacity
|UNDERSTANDING DOT TIRE INFLATION PRESSURES AND LOAD CAPACITY|
This document includes information regarding proper inflation pressures for Highway use of DOT tires.
TIRE SIDEWALL INFORMATION
PROPER INFLATION PRESSURE
Again, the pressure listed on the tire sidewall is the maximum pressure and not intended as a guide for normal inflation pressure. These things are dictated by the vehicles weight and use (ie: high speed). Always start with the vehicle manufacturer’s information on inflation pressures. With modified vehicles, or vehicles using tire sizes other than OE, it is valuable to understand the weight bias of the vehicle and intended use along with the maximum load capacity and inflation.
Always use a tire with a load carrying capacity that matches or exceeds the weight carrying capacity of the OE tire. With light truck tires and applications, the load capacity is more critical than the load range when choosing non OE sizes. Due to the reduced load capacity on P-metric tires, Mickey Thompson does not recommend their use on O.E. LT tire applications.
It is also important not to check tire pressure when the tires are hot after use. Over-inflation can produce a harsh ride, makes the tires susceptible to impact damage, and promotes faster than normal tread wear along with decreased traction performance. Under-inflation (or over-loading) will cause excessive heat build up which can lead to tire failure.
For proper tire inflation on Mickey Thompson Tires, please contact M/T Tech Department at 800-222-9092 (Option 4) with original tire size and stock tire pressure. (The front and rear stock tire pressure can be found on the driver door placard/sticker)

|MICKEY THOMPSON® METRIC CONVERSION CHARTS|
5. Tire Inflation - Nitrogen
|TIRE INFLATION – NITROGEN|
Nitrogen inflation in tires is gaining popularity in the light vehicle (passenger and light truck) market. Nitrogen inflation in tires is not new to the tire industry however, and has been used under severe service conditions such as in large off-road tires, aircraft tires (as fire prevention) and racing tires for many years. Nitrogen inflation does not harm tires nor does it affect the warranty.
One of the most important factors in tire care is maintaining proper inflation pressure. The proper tire inflation for a vehicle is specified by the vehicle manufacturer and can usually be found on the tire placard (or sticker) attached to the vehicle door edge, door post, glove box door or fuel door as well as the vehicle owner’s manual. Proper tire inflation, whether nitrogen or normal air, helps tires wear longer, saves fuel and helps prevent accidents. Under inflation, regardless of the inflation gas, can make it harder to steer and stop your vehicle, result in loss of vehicle control, cause sudden tire destruction, and lead to serious injury or death.
Nitrogen inflation will not prevent damage or loss of inflation due to road hazards. Nitrogen inflation will also not prevent tire damage due to under inflation, overloading of off road service. Tire inflation should always be checked and adjusted to proper inflation pressure on a regular basis (at least monthly and before long trips), regardless of the inflation gas, to provide optimum tire performance.

6. Tires and Tubes Affected By Flood Waters
|TIRES AND TUBES AFFECTED BY FLOOD WATERS|
The Mickey Thompson Tires and Wheels Company recommend the following with the respect to tires and inner tubes that have been exposed to flood waters. Flood water contains contaminants such as oil, grease, salt and other contaminants which can be damaging to tires and tubes. This recommendation applies to all types of tires including passenger, light truck, truck, off-the-road and agricultural tires:
This is Mickey Thompson General Technical Bulletin #6.
7. Tire Mixing
When tires need to be replaced, do not guess what tire is right for the vehicle. You must consult the tire placard, which is normally located on the vehicle door edge, door post, glove box or fuel door. The placard tells you the size of the tires (including the spare) that were mounted on the vehicle as original equipment (OE). It also includes the recommended cold inflation pressures for the front/rear axles and the spare tire as well as the load capacity. If the vehicle does not have a placard, check the owner’s manual or consult with the vehicle manufacturer or tire manufacturer.
IMPORTANT: Always check the vehicle manufacturer’s recommendations for the OE tire size, load capacity, inflation pressure, and speed symbol information before replacing a tire with a different size and construction. It is not always possible – usually due to temporary emergency conditions – to select the same tire size for a replacement tire. Never choose a smaller size replacement tire and/or a tire with less load carrying capacity than the specified size on the vehicle placard.
The RMA provides the following insight for emergency/temporary nonstandard fitments:
The following is a passage from the RMA Replacement Guidelines for Passenger & Light Truck Tires manual.
It is recommended that all four tires be of the same size, speed rating, and construction (radial, non-radial). In some cases the vehicle manufacturer may require different sized tires for either the front or rear axles. NEVER mix P-Metric or European Metric passenger tires with light truck sized tires on the same vehicle.
Match tire size designations in pairs on an axle, except for temporary use of a spare tire. (See Mickey Thompson Tech Bulletin #15 “Replacing Less Than Four Tires”).
If two radial tires and two non-radial tires must be used on a vehicle, put radials on the rear axle. If radial and non-radial tires are used on a vehicle equipped with dual rear tires, the radial tires may be used on either axle.

8. Safety Warning – Speed Rated Tires
|SAFETY WARNING – SPEED RATED TIRES|
The following is current information regarding speed rated tires. Please note that many of today’s vehicles are equipped with speed rated tires. Please not that many of today’s vehicles are equipped with speed rated tires. It is NOT recommended that tires on these vehicles be replaced with tires which exhibit a lower speed rating than those specified by the vehicle manufacturer.
Safety Rules for Selection, Mixing, Repairing, Retreading, or Alteration of Speed Rated Tires
It is important, for the safety of the consumer, that the following safety rules be followed in the selection, mixing, and servicing of speed rated tires.
A. When replacement of tires is desired, consult the placard (normally located on the door frame or glove box door) or the owner’s manual for correct size. If the tires shown on the vehicle placard do not have speed ratings, the appropriate size tire with any speed rating may be applied, if desired. When the placard tire size nomenclature contains a speed symbol, for example P205/60HR15, the replacement tire must have the same or higher speed rating symbol if the speed capability of the vehicle is to be maintained. IF THE REPLACEMENT TIRE IS NOT SPEED RATED, OR HAS A LOWER SPEED RATING THAN INDICATED ON THE VEHICLE PLACARD, THE SPEED CAPABILITY OF THE VEHICLE IS LIMITED BY THE SPEED CAPABILITY OF THE REPLACEMENT TIRE. A Mickey Thompson produced dot tire without a speed rating has a max highway speed of 85 mph.
Follow the recommendations contained in RMA publications for other considerations in the selection of replacement tires.
IF TIRES OF DIFFERENT SPEED RATINGS ARE MOUNTED ON A VEHICLE, THE TIRE WITH THE LOWEST SPEED RATING WILL LIMIT PERMISSIBLE TIRE RELATED VEHICLE SPEED.
If any replacement tire is not speed rated, the speed capability of the vehicle is limited by the maximum speed of that tire (85 mph for Mickey Thompson produced tires).
C. Retreading, Repairing , or Alteration of Speed Rated Tires
SPEED RATING NO LONGER APPLIES TO A MICKEY THOMPSON PRODUCED TIRE THAT HAS BEEN ALTERED (for example, by retreading or repairing).
This is Mickey Thompson General Technical Bulletin #8.
9. Passenger and Light Truck Used Tires
|PASSENGER AND LIGHT TRUCK USED TIRES|
Below is a link to the Tire Information Service Bulletin by the Rubber manufacturers Association (RMA) regarding previously used tires on a passenger or light truck vehicle. Anyone who is considering the purchase and/or installation of used tires, especially used tires with an unknown history, should read the bulletin carefully.
Consumers should be aware of possible serious risk associated with the installation and use of previously used tires. While tires are designed and built to provide many thousands of miles of excellent service, they must be maintained properly throughout their service life to achieve optimal performance. Proper tire maintenance includes regular (at least monthly) visual tire inspections for signs of damage or abuse (ie. Cuts, cracks, bulges, snags, irregular wear, etc.) and inflation pressure checks. Tires can be damaged over the course of their service life due to abuse or improper service, maintenance, repair, or storage conditions, and such damage can eventually lead to tire failure. Only the original owner of a new tire can know the full extent of a particular tire’s service and maintenance, and the conditions of use or abuse the tire has experienced. Thus, Mickey Thompson Tire fully endorses the RMA Tire Information Service Bulletin, “Passenger and Light Truck Used Tires”.
Mickey Thompson urges that used tires should not be purchased, sold, or installed if they exhibit any of the conditions listed in the RMA bulletin, or if the used tires are offered by anyone other than a qualified tire service professional at a reputable new tire sales facility. Also, it should be noted that any used tire deemed not suitable for immediate service is also not suitable for spare tire applications. When a faulty spare tire is eventually used, it will be dangerous in service.
Consumers should also be wary of used tires that:

|MICKEY THOMPSON NATURAL RUBBER RACING TUBES|
Besides being required for air retention, Mickey Thompson racing tubes can enhance reaction time, increase stability and helps the tire maintain the proper shape to reduce sidewall shock and deflection.
Note: Always run the correct size natural rubber tube for the application. The wrong tube type and size will always fail.
When buying tube type tires it is important to understand the reasons behind making a tire tube type and when it is appropriate to run the tire with or without a tube. The decision to run with or without tubes should be based on safety and performance, not cost.

6. Proper Measurement of M/T ET Drag AND ET Street R (Bias Tires)
|PROPER MEASUREMENT OF M/T ET DRAG AND ET STREET R (Bias Tires)|
|Proper measurement of a tire is very important when choosing a tire as it will affect many things such as engine R.P.M., vehicle fitment, roll out and ground clearance issues.|
7. Backspacing and Offset
|BACKSPACING AND OFFSET|
Backspace and offset are two ways of describing where the wheel sits in relationship to the hub. As such, there is a relationship between the two making – it possible to convert from one to the other.
Backspacing is the easiest to understand. It is simply the distance from the back of the mounting pad to the back lip of the wheel. It is measured by laying the wheel on its face, placing a straight edge across the wheel, and then measuring down to mounting face. The higher this measurement the more the wheel is pushed inboard towards the car’s centerline, as shown in the illustration above.
Offset is the distance from the mounting surface to the centerline of the wheel, expressed in millimeters. Positive offset means that the wheels are pushed inboard towards the centerline of the car like a car with front wheel drive. Negative means that the wheels are moved outboard towards the fenders, widening the track.
8. Tire use on a Dyno
|TIRE USE ON A DYNO|
|Mickey Thompson tires which have been subject to use on a Dyno must no longer be used for subsequent, normal service. Use of Mickey Thompson tires on a Dyno will invalidate the tire warranty.|

|TIRE-WHEEL MATCH MOUNTING FOR OPTIMUM UNIFORMITY|
|Typical details and procedures for proper match mounting are as follows:|
2. The Importance of Proper Front End Alignment
|THE IMPORTANCE OF PROPER FRONT END ALIGNMENT|
It is important to remember that when installing wider tires and/or wider wheels with more negative offset than factory and when ride height is changed, especially on late model IFS (Independent Front Suspension) equipped foreign & domestic P/U’s & SUV’s, it also changes alignment settings and load on the steering components.
When front-end alignment goes uncorrected, it shows up on the tread surface of tires which have excessive wear to the inside or outside portion of the tread. The same can be said of tires with a ‘chopped’ and/or ‘feathered’ look to the tread. Most often, we can trace tires requested for adjustment due to “fast tread wear” back to a vehicle with poor or uncorrected front-end alignment.
Here is the way to avoid this unwarrantable problem:
4. Maintaining M/T Classic III Wheels
|MAINTAINING M/T CLASSIC III WHEELS|
|M/T Classic III wheels are not clear or powder coated. This means that the end user must maintain their wheels to preserve that “out of the box” look. There is no warranty on the finish on M/T Classic II wheels, so it is important that you take the time to keep your wheels looking good. The follow procedures will help you.|
5. Tire Inflation Pressures
|TIRE INFLATION PRESSURES|
Federal regulations make it mandatory for tire manufacturers to place permanent data on the side of all tires showing maximum load and inflation. The inflation pressure shown is the “maximum” allowable under any circumstance. The maximum pressure is the uppermost limit and it is necessary only when heavy loads are carried in order to achieve the full safe load carrying limit of the tire, or when sustained periods of high speed driving are expected.
The pressure listed on the tire sidewall is the maximum pressure to be used for the tire. It is not intended as a guide for normal inflation pressure. If the vehicle is equipped with a tire that is the same “size” as the OE tire, has the same max pressure rating and has the same load index always check the vehicle manufacturer’s information on inflation pressures before inflating any tire. This is typically located on the vehicle tire placard.
The user may need to make adjustments to air pressure if the tire size or service description differs from what the vehicle was originally equipped with. For suggested air pressure in the Mickey Thompson Tires used on the vehicle, refer to the information in the Tech Bulletin section or contact the Mickey Thompson Tires tech dept. at (330) 928-9092 and have your OE tire size ( located on the vehicle placard), OE cold inflation pressure (located on the vehicle placard), and new tire size available for the tech staff.
When high speed driving and /or driving with maximum load as prescribed by the vehicle manufacturer), it is most important to follow the auto manufacturer’s recommendation for increasing tire pressure. However, do not ‘bleed’ or reduce pressure when the tires are hot from driving. Over-inflation may produce a harsh ride, which may make tires susceptible to impact damage and may cause faster than normal tread wear and may cause traction and cornering capabilities to decrease. Under-inflation may cause excessive heat build-up, which could cause tire failure.
6. Replacing Less Than Four Tires
|REPLACING LESS THAN FOUR TIRES|
When replacing tires on a vehicle, it is recommended and preferred that all four tires be replaced at the same time for continued optimal vehicle performance. However, for those cases where this is not feasible, below are some general guidelines to consider when replacing less than four tires for a light vehicle, whether it is one or two tires. If the vehicle manufacturer has alternate recommendations, always follow their recommendations.
Replacing Two (2) Tires – When a pair of replacement tires is selected in the same size and construction as those on the vehicle, the two newer tires should be installed on the rear axles unless the new replacement tires are of a lower speed rating (see Mickey Thompson Tech Bulletin #14 “Tire Mixing”). Generally, new tires with deeper tread will provide better grip and evacuate water more effectively, which is important as a driver approaches hydroplaning situations. Placing greater traction on the rear axle on wet surfaces is necessary to prevent possible oversteer condition and possible loss of vehicle control, especially during sudden maneuvers.
Replacing One (1) Tire – Replacing a single tire on a vehicle can have adverse affect on suspension systems, gear ratios, transmission, and tire treadwear. If single tire replacement is unavoidable, it is recommended that the single new tire be paired with the tire that has the deepest tread and both be placed on the rear axle. Placing greater traction on the rear axle on wet surfaces is necessary to prevent a possible oversteer condition and possible loss of vehicle control, especially during sudden maneuvers.
