WARNING
DISREGARDING ANY OF THE SAFETY PRECAUTIONS AND INSTRUCTIONS CONTAINED IN THIS MANUAL MAY RESULT IN TIRE FAILURE OR EXPLOSION CAUSING SERIOUS PERSONAL INJURY OR DEATH.

|
THE IMPORTANCE OF TIRES
|
The tire is the only contact between your vehicle and the ground. In order to ensure greater safety and to achieve longer tire life, it is essential to adhere to certain principles. Tires are of the utmost importance and the cost of regular maitenance is more than justified.
Consequently, we recommend that you read and understand the following information.
|
|
DRIVING ON ANY TIRE THAT DOES NOT HAVE THE CORRECT INFLATION PRESSURE IS DANGEROUS
|
Any underinflated tire builds up excessive heat that may result in sudden tire destruction. If tires are supplied as original equipment, refer to the tire decal on the vehicle (check vehicle and/or vehicle owner’s manual for placard location) for the recommended operating pressures. For replacement tires, the correct inflation pressure will be provided by your tire retailer; if not, refer to the vehicle placard.
These inflation pressures must be maintained as a minimum. However, do not exceed the maximum pressure rating indicated on the sidewall.
|
|
CHECK THE COLD INFLATION PRESSURE IN ALL YOUR TIRES, INCLUDING THE SPARE, AT LEAST ONCE A MONTH
|
Failure to maintain correct inflation may result in improper vehicle handling and may cause rapid and irregular tire wear, sudden tire destruction, loss of vehicle control, and serious personal injury. Therefore, inflation pressures should be checked at least once a month and always before long distance trips. This applies to all tires, including sealant types, and self-supporting tires which are as susceptible to losing air pressure as any other type of tire if not properly maintained.
Pressures should be checked when tires are cold; in other words, before they have been driven on. Driving, even for a short distance, causes tires to heat up and air pressure to increase.
|
|
CHECKING PRESSURE WHEN TIRES ARE HOT
|
If pressures are checked after tires have been driven for more than three minutes or more than 2 km, the tires become hot and the pressures will increase by approximately 4 psi (30 kPa). Therefore, when tire pressure is adjusted under these conditions, it should be increased to a gauge reading of 4 psi (30 kPa) greater than the recommended cold inflation pressure.
For example only:
| Gauge reading of hot tire: |
32 psi |
(220 kPa) |
| If recommended cold inflation is: |
30 psi |
(205 kPa) |
| Desired gauge reading of hot tire is: |
30 + 4 = 34 psi |
(205 + 30 = 235 kPa) |
| Therefore add: |
2 psi |
(15 kPa) |
Check cold pressure as soon as possible, preferably within 24 hours. “Bleeding” air from hot tires could result in underinflation. Use an accurate tire gauge to check pressures. Never allow children to inflate or deflate tires.
|
|
TIRE SPINNING
|
Do not spin wheels in excess of 55 km/h as indicated on the speedometer. Excessive speed in a free-running, unloaded tire can cause it to “explode” from centrifugal force. The energy released by such an explosion is sufficient to cause serious physical injury or death. Never allow anyone to stand near or behind the spinning tire.
When in mud, sand, snow, ice, or other slippery conditions, do not engage in excessive wheel spinning. Accelerating the motor excessively, particularly with automatic transmission vehicles, may cause a drive tire that has lost traction to spin beyond its speed capability. This is also true when balancing a drive tire/wheel on the vehicle using the vehicle engine to spin the tire/wheel assembly.
|
|
HIGH SPEED DRIVING CAN BE DANGEROUS
|
Correct inflation pressure is especially important. However, at high speeds, even with the correct inflation pressure, a road hazard, for example, is more difficult to avoid and, if contact is made, has a greater chance of causing tire damage than at a lower speed. Moreover, driving at high speed reduces the reaction time available to avoid accidents and bring your vehicle to a safe stop.
If you see any damage to a tire or wheel, replace with the spare at once and visit any participating Michelin® retailer.
Exceeding the maximum speeds shown in the following table for each type of Michelin® tire will cause the tire to build up excessive heat, which can cause tire damage that could result in sudden tire destruction and rapid air loss. Failure to control a vehicle if a tire experiences sudden air loss can lead to an accident.
In all cases, you should not exceed reasonable speeds as indicated by the legal limits and driving conditions.
|
|
SPEED RATINGS

*Some V (or VR) rated tires may have a speed capacity greater than 240 km/h. Consult your participating Michelin ® retailer for maximum speed rating if your vehicle capability exceeds this speed.
**Z (or ZR) rated tires are designed for use on cars with maximum speed capabilities in excess of 270 km/h. (W, Y and (Y) speed ratings are sub-categories of Z). Consult your Michelin ® retailer for maximum speed capabilities.
Although a tire may be speed-rated, we do not endorse the operation of any vehicle in an unsafe or unlawful manner. Speed ratings are based on laboratory tests which relate to performance on the road, but are not applicable if tires are underinflated, overloaded, worn out, damaged, altered, improperly repaired or retreaded. Furthermore, a tire’s speed rating does not imply that a vehicle can be safely driven at the maximum speed for which the tire is rated, particularly under adverse road and weather conditions or if the vehicle has unusual characteristics.
Michelin ® passenger tires that do not have a speed symbol on the sidewall have a maximum speed rating of 170 km/h.
Light truck highway tires that do not have a speed symbol on the sidewall of the tire have a maximum speed rating of 140 km/h. Some light truck tires may have higher maximum speed ratings; consult any Michelin ® retailer.
The speed and other ratings of retreaded tires are assigned by the retreader and supersede the original manufacturer’s ratings.
IMPORTANT: In order to maintain the speed capability of the vehicle, replacement tires must have speed ratings equal to or higher than those fitted as original equipment (as indicated on the vehicle tire placard or in the owner’s manual). If tires with lower speed ratings are fitted, the speed capability of the vehicle will be lowered to the maximum speed capability of the replacement tires as indicated in the speed ratings table above.
REMEMBER... High-speed driving can be dangerous and may damage your tires.
AND... When driving at highway speeds, correct inflation pressure is especially important.
WINTER TIRES - Michelin ® brand winter tires that do not have a speed symbol on the sidewall or tires with the Q symbol have a speed rating of 160 km/h. Winter tires with a speed symbol have a maximum speed rating in accordance with the symbol.
Studded tires have a maximum speed rating of 150 km/h.

|
INSPECT YOUR TIRES. DO NOT DRIVE ON A DAMAGED TIRE OR WHEEL
|
Road hazards
Driving over potholes, glass, metal, rocks, wood debris and the like can damage a tire and should be avoided. Unavoidable contact with such hazards should prompt a thorough tire inspection. Any time you see any damage to your tires or wheels, replace with a spare at once and immediately visit any participating Michelin® retailer for advice.
Inspection
When inspecting your tires, including the spare, check air pressures. If the pressure check indicates that one of your tires has lost 2 psi (15 kPa) of pressure or more, look for signs of penetrations, valve leakage or wheel damage that may account for the air loss.
Always look for bulges, cracks, cuts, penetrations, and abnormal tire wear, particularly on the edges of the tire tread, which may be caused by misalignment or underinflation. If any such damage is found, the tire must be inspected by any participating Michelin® retailer at once. The use of a damaged tire could result in tire destruction.
All tires will wear out faster when subjected to high speeds as well as hard cornering, rapid starts, sudden stops, frequent driving on roads which are in poor condition, and off-road use. Roads with holes and rocks or other objects can damage tires and cause misalignment of your vehicle. When driving on such roads, drive carefully and slowly, and before driving again at normal or highway speeds, examine your tires for any damage, such as cuts, bulges, penetrations, unusual wear patterns, etc.
|
|
WEAR BARS
|
Michelin® tires contain “wear bars” in the grooves of the tire tread which show up when only 2/32nds of an inch (1.6 mm) of tread is remaining. At this stage, tires must be replaced. Tires worn beyond this stage are dangerous.
|
|
DO NOT OVERLOAD; DRIVING ON ANY OVERLOADED TIRE IS DANGEROUS
|
The maximum load rating of your tires is marked on the tire sidewall. Do not exceed this rating. Follow the loading instructions of the manufacturer of your vehicle and this will ensure that your tires are not overloaded. Tires which are loaded beyond their maximum allowable loads for the particular application will build up excessive heat that may result in sudden tire destruction.
Do not exceed the gross axle weight rating for any axle on your vehicle.
|
|
TRAILER TOWING
|
If you anticipate towing a trailer, you should see any participating Michelin® retailer for advice concerning the correct size of tire and pressures. The size and pressures will depend upon the type and size of trailer and hitch utilized, but in no case may the maximum cold inflation pressure or tire load rating be exceeded. Check the vehicle placard and the owner’s manual supplied by the manufacturer of your vehicle for further recommendations on trailer towing.
|
|
WHEEL ALIGNMENT AND BALANCING ARE IMPORTANT FOR SAFETY AND MAXIMUM MILEAGE FROM YOUR TIRES
|
CHECK TIRE WEAR AT LEAST ONCE A MONTH
If your tires are wearing unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread, or if you detect excessive vibration, your vehicle may be out of alignment or balance. These conditions not only shorten the life of your tires but also adversely affect the handling characteristics of your vehicle, which could be dangerous.
If you detect irregular wear or vibration, have your alignment and balance checked immediately. Tires that have been run underinflated will show more wear on the shoulders than in the center of the tread.
|
|
TIRE MIXING
|
For best performance, it is recommended that the same size and type of tire be used on all four wheel positions. Before mixing tires of different types in any configuration on any vehicle, be sure to check the vehicle manufacturer’s owner’s manual for its recommendations.
It is especially important to check the vehicle manufacturer’s owner’s manual before mixing, matching or replacing tires on 4-wheel drive vehicles, as this may require special precautions.
|
|
WINTER DRIVING
|
Tires which meet the Rubber Manufacturers Association (RMA) definition of snow tires are marked M/S, M+S, or M&S. On such tires, this designation is molded into the sidewall. Tires without this notation are not recommended for winter driving.
NOTE: While all-season tires are designed to provide reliable performance in moderate winter conditions, the use of four winter tires is recommended for optimal performance.
Tires designated for use in severe winter conditions are marked with at least one sidewall with the letter “M” and “S” plus a pictograph of a mountain with a snowflake on it.
|
|
TIRE ROTATION
|
To obtain maximum tire life, it may be necessary to rotate your tires. Refer to your vehicle owner’s manual for instructions on tire rotation. If you do not have an owner’s manual for your vehicle, Michelin® brand recommends rotating your tires every 10,000 to 12,000 km.
Monthly inspection for tire wear is recommended. Your tires should be rotated at the first sign of irregular wear, even if it occurs before 10,000 km. This is true for all vehicles.
When rotating tires with a directional tread pattern, observe the arrows molded on the sidewall which show the direction in which the tire should turn. Care must be taken to maintain the proper turning direction.
As a general rule, whenever only two tires are replaced, the new ones should be put on the rear.
|
|
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON SUVs AND LIGHT TRUCKS
|
Due to their size, weight and higher center of gravity, vehicles such as SUVs and light trucks do not have the same handling characteristics as automobiles. Because of these differing characteristics, failure to operate your SUV/light truck in a proper and safe manner can increase the likelihood of vehicle rollover. Modifications to your SUV/light truck tire size, tire type, wheels or suspension can change its handling characteristics and further increase the likelihood of vehicle rollover. Whether your SUV/light truck has the original equipment configuration for tires, wheels and suspension, or whether any of these items have been modified, always drive safely, avoid sudden, sharp turns or lane changes and obey all traffic laws. Failure to do so may result in loss of vehicle control leading to an accident and serious injury or death.
|
|
TIRE ALTERATIONS
|
Do not make or allow to be made any alteration on your tires. Alterations may prevent proper performance, leading to tire damage which can result in an accident. Tires which become unserviceable due to alterations such as truing, whitewall inlays, addition of balancing or sealant liquids, or the use of tire dressings containing petroleum distillates are excluded from warranty coverage.
|
|
REPAIRS
|
WHEREVER POSSIBLE, SEE A MICHELIN® TIRE RETAILER
If any Michelin® tire sustains a puncture, have the tire demounted and thoroughly inspected by any participating Michelin® retailer for possible damage that may have occurred.
A tread area puncture in any Michelin® passenger or light truck tire can be repaired provided that the hole is not more than 1/4" in diameter, that not more than one radial cable per casing ply is damaged, and that the tire has not been damaged further by the puncturing object or by running underinflated. Tire punctures consistent with these guidelines can be repaired by following Rubber Manufacturers Association (RMA) recommended repair procedures. If damage exceeds these guidelines, the tire must be replaced.
Plug-only repairs done on-the-wheel are considered improper and therefore not recommended. Such repairs are not reliable and may cause further damage to the tire.
|
|
STORAGE
|
Tires contain waxes and emollients to protect their outer surfaces from ozone and weather checking. As the tire rolls and flexes, the waxes and emollients continually migrate to the surface, replenishing this protection throughout the normal use of the tire. Consequently, when tires sit outdoors, unused for long periods of time (a month or more) their surfaces become dry and more susceptible to ozone and weather checking, and the casing becomes susceptible to flat spotting. For this reason tires should always be stored in a cool, dry, clean, indoor environment. If storage is for one month or more, eliminate the weight from the tires by raising the vehicle or by removing the tires from the vehicle. Failure to store the tires in accordance with these instructions could result in premature aging of the tires and sudden tire failure.
When tires are stored, be sure they are placed away from sources of heat and ozone such as hot pipes and electric generators. Be sure that surfaces on which tires are stored are clean and free from grease, gasoline or other substances which could deteriorate the rubber. (Tires exposed to these materials during storage or driving could be subject to sudden failure.)
|
|
FOLLOW THESE MOUNTING RECOMMENDATIONS
|
Tire changing can be dangerous and must be done by professionally trained persons using proper tools and procedures as specified by the Rubber Manufacturers Association (RMA).
Your tires should be mounted on wheels of the correct size and type and which are in good, clean condition. Bent, chipped or rusted wheels may cause tire damage. The inside of the tire must be free from foreign material. Have your tire retailer check the wheels before mounting new tires. A tire mounted on a mismatched rim can explode during mounting. Also, mismatched tires and rims can result in dangerous tire failure on the road. If a tire is mounted by mistake on a wrong-sized rim, do not remount it on the proper rim — scrap it. It may have been damaged internally (which is not externally visible) by having been dangerously stretched, which could result in tire destruction.
Old valves may leak.When new tubeless tires are mounted, have new valves of the correct type installed. Be sure that all your valves have suitable valve caps. The valve cap is the primary seal against air loss. Tubeless tires must be mounted only on wheels designed for tubeless tires, i.e., wheels which have safety humps or ledges.
It is recommended that you have your tires and wheels balanced. Tires and wheels which are not balanced may cause steering difficulties, a bumpy ride, and irregular tire wear.
|
|
TEMPORARY SPARE TIRES
|
When using any temporary spare tire, be sure to follow the vehicle manufacturer’s instructions.
|
DRIVING ON STUDDED PASSENGER TIRES (In States or Provinces where legally permitted)
|
Only new passenger tires should be fitted with studs. For maximum effectiveness on tires which are drilled for studs, all four tires on a vehicle should be fitted with studs. If only the two rear tires are studded, maximum efficiency in handling and braking will not be realized. On wet or dry pavement, the rear tires will have a larger slip angle than the front tires, possibly producing an oversteer condition. On ice and packed snow, the rear tires will have a small slip angle and relatively good traction compared to a very large slip angle and poor traction on the front tires. These factors may cause a severe understeer condition thereby reducing the steering and braking ability of the vehicle. On vehicles with front wheel drive, adverse handling characteristics can be introduced by mounting studded snow tires on front wheels only.
Failure to observe recommended precautions can lead to erratic vehicle behaviour and/or tire damage possibly resulting in an accident.
|
|
REMEMBER... TO AVOID DAMAGE TO YOUR TIRES AND POSSIBLE ACCIDENTS:
|
- CHECK TIRE PRESSURE AT LEAST ONCE A MONTH WHEN THE TIRES ARE COLD AND BEFORE LONG TRIPS.
- DO NOT UNDERINFLATE/OVERINFLATE.
- DO NOT OVERLOAD.
- DRIVE AT MODERATE SPEEDS, OBSERVE LEGAL LIMITS.
- AVOID DRIVING OVER POTHOLES, OBSTACLES, CURBS OR PAVEMENT EDGES.
- AVOID EXCESSIVE WHEEL SPINNING.
- IF YOU SEE ANY DAMAGE TO A TIRE, REPLACE IT WITH THE SPARE AND VISIT ANY MICHELIN® RETAILER AT ONCE.
- IF YOU HAVE ANY QUESTIONS, CONTACT YOUR MICHELIN® RETAILER.
FAILURE TO OBSERVE ANY OF THE RECOMMENDED PRECAUTIONS CONTAINED IN THIS OWNER’S MANUAL CAN LEAD TO ERRATIC VEHICLE BEHAVIOUR AND/OR TIRE DAMAGE POSSIBLY RESULTING IN AN ACCIDENT.
