Maximum Pressure indicates the maximum permissible cold tire infla- tion pressure for this tire. The TIN may be found on one or both sides of the tire but the date code may only be on one side. Look for the TIN on the outboard side of tires as mounted on the vehicle. If the TIN is not found on the outboard sidethen you will find it on the inboard side of the tire.

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlledconditions on a specified government test course. For example, a tire graded 150 would wear one and one- half (1
1/2) times as well on the gov-
ernment course as a tire graded 100. The relative performance of tiresdepends upon the actual conditions of their use, however, and may depart significantly from the norm due tovariations in driving habits, service practices and differences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Thosegrades represent the tire’s ability to stop on wet pavement as measured
WA R N I N GOverloading of your tire isdangerous. Overloading can cause tire failure, affect vehi-cle handling, and increase your stopping distance. Use tires of the recommended loadcapacity for your vehicle. Never overload them.

under controlled conditions on speci- fied government test surfaces of asphalt and concrete. A tire marked C may have poor traction perfor- mance. The temperature grades are A (the highest), B and C, representing the tire’s resistance to the generation ofheat and its ability to dissipate heat when tested under controlled condi- tions on a specified indoor laboratorytest wheel. Sustained high tempera- ture can cause the material of the tire to degenerate and reduce tire life, andexcessive temperature can lead to sudden tire failure. The grade C cor- responds to a level of performancewhich all passenger car tires must meet under the Federal Motor Vehi- cle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory testwheel than the minimum required by law.

Proper tire inflation pressure is essential for the safe and satisfactory operation of yourvehicle. The wrong tire pressure will cause problems in three major areas: Safety Too little pressure increases flexing in thetire and can cause tire failure. Too muchpressure can cause a tire to lose its ability to cushion shock. Objects on the road and potholes could then cause tire damage thatmay result in tire failure. Economy The wrong tire pressure can cause unevenwear patterns in the tire tread. These abnormal wear patterns will reduce the tread life, and the tire will have to bereplaced sooner. Too little pressure also makes it harder for the tire to roll, and this uses up more fuel. Ride comfort and vehicle stability The superior riding experience built into your vehicle partly depends on the correcttire pressure. Too much pressure gives an uncomfortable and jarring ride. Too little pressure feels as if your vehicle is slow torespond. Unequal tire pressures can make steering your vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placard attached to the driver’s door sill. (Refer to “Tire and loading information plac-ard” on page 11-2.) The recommended infl
ation pressures under
normal driving conditions should be used forthe tires listed below. Tire pressures should be checked, and adjusted if necessary, at least once a month. Pressures should be checked more oftenwhenever weather temperatures change severely, because tire pressures change with outdoor temperatures. The pressures listedare always “cold inflation pressure”. Cold inflation pressure is measured after the vehicle has been parked for at least threehours or is driven less than 1 mile (1.6 km) after having been parked for three hours.

Cold inflation pressure must not go above the maximum values molded into the tire side- wall. After driving several miles, your tire inflation pressure may increase 2 to 6 psi (14to 41 kPa) from the cold inflation pressure. Do not let air out of the tires to get back to the specified cold pressure, or your tires will betoo low. Check your tires each time you refuel. If one tire looks lower than the others, check thepressure for all of them.You should also take the following safety pre- cautions: Keep your tires inflated to the recom- mended pressures. (See the tire and load-ing information placard attached to the driver’s door sill.) Stay within the recommended load limits. Make sure that the weight of any load in your vehicle is evenly distributed. Drive at safe speeds. After filling your tires to the correct pres- sure, check them for damage and air leaks. Be sure to reinstall the caps on thevalve stems.

The following maintenance steps are recom- mended:
Check tire pressures regularly. Have regular maintenance done on the wheel balance and front and rear suspen- sion alignment. Rotate your tires regularly as described in the “Tire rotation” section on page 9-19.

Tread wear indicators are built into the origi- nal equipment tires on your vehicle to helpyou know when your tires should be replaced. Many states have laws requiring that you replace your tires at this point.These indicators are molded into the bottom of the tread grooves and will appear when the tire tread is worn down to 1/16 inch (1.6mm).
Replacing tires and wheels
CAUTION Avoid using different
size tires from the one
listed and the combined use of different types of tires, as this can affect driving safety.Refer to “Tires and wheels” on page 11-5. On all-wheel drive vehicles, always use tires of the same size, same type, and same brand, and which have no wear differences. Using tires that differ in size, type, brand or thedegree of wear, will increase the differential oil temperature, resulting in possible damage to the driving system. Further, the drive trainwill be subjected to excessive loading, possi- bly leading to oil leakage, component sei- zure, or other serious problems. Only Mitsubishi Motors Authorized wheels should be used, because your vehicle isequipped with a tire pressure monitoring sys- tem. Use of another type of wheel risks air leaksand sensor damage, as it will not be possible to install the tire pressure sensor properly.

To even out the wear on your tires and makethem last longer, Mitsubishi Motors Corpora- tion recommends that you rotate your tires at the mileage listed in the “WARRANTY ANDMAINTENANCE MANUAL”. However, the timing for tire rotation may vary according to your vehicle condition,road surface conditions, and your own per- sonal driving habits. Any time you notice unusual wear, rotate your tires as soon as pos-sible. When rotating tires, check for uneven wear, damage, and wheel alignment. Abnormal wear is usually caused by a wrong tire pres-sure, wheels that are not aligned properly, wheels that are out-of-balance, or severe braking.Check with an authorized Mitsubishi Motors dealer or a repair facility of your choice to find out the reason for uneven tread wear.
The first tire rotation is the most important one. It will allow all your tires to wear evenly.
NOTE
Tire wear indicators can have different marks and locations depending on the tire manufac- turer.
Tire rotation
CAUTION A compact spare tire can be installed tempo- rarily in place of a tire that has been removed during the tire rotation. However, it must not be included in the regular tire rotationsequence.Tires that do not have

If the tires have arrows (A) indicating the correct direction of rotation, swap the front and rear tires on the left-hand side of the vehicle and the front and rear tires on the right-hand side of the vehicle separately.Keep each tire on its original side of the vehicle. When installing the tires, make sure the arrows point in the
direction in which the
wheels will turn when the vehicle moves for- ward. Any tire whose arrow points in the wrong direction will not perform to its fullpotential.CAUTION Avoid the combined use of different types of tires. Using different types of tires can affect vehicle performance and safety.CAUTIONFront
