Wheel balance Unbalanced wheels may affect vehicle handling and tire life. Even with regular use, wheels can get out of balance. Therefore, they should be balanced as required. Wheel balance service should be performed with the wheels off the vehicle. Spin balancing the wheels on the vehicle could lead to mechanical damage. For additional information regarding tires, refer to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada) in the INFINITI Warranty Information Booklet. ● INFINITI recommends that the road wheels be waxed to protect against road salt in areas where it is used during winter. Spare tire (TEMPORARY USE ONLY (T-type) spare tire) Observe the following precautions if the T-type spare tire must be used, otherwise your vehicle could be damaged or involved in an accident. ● With the TEMPORARY USE ONLY spare tire installed do not drive your vehicle at speeds faster than 50 MPH (80 km/h). ● When driving on roads covered with snow or ice, the TEMPORARY USE ONLY spare tire should be used on the front wheels and original tire used on the rear wheels (drive wheels). Use tire chains only on the two rear original tires. ● Tire tread of the TEMPORARY USE ONLY spare tire will wear at a faster rate than the standard tire. Replace the spare tire as soon as the tread wear indicators appear. ● Do not use the spare tire on other vehicles. ● Do not use more than one spare tire at the same time. ● Do not tow a trailer when the TEMPORARY USE ONLY spare tire is installed. WARNING ● The T-type spare tire should be used for emergency use. It should be replaced with the standard tire at the first opportunity to avoid possible tire or differential damage. ● Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid sharp turns and abrupt braking while driving. ● Periodically check spare tire inflation pressure. Always keep the pressure of the TEMPORARY USE ONLY spare tire at 60 psi (420 kPa, 4.2 bar). Always keep the pressure of the full size spare tire (if so equipped) at the recommended pressure for standard tires, as indicated on the Tire and Loading Information label. For Tire and Loading Information label location, see "Tire and Loading Information label" in the index of this manual. Care of wheels ● Wash the wheels when washing the vehicle to maintain their appearance. ● Clean the inner side of the wheels when the wheel is changed or the underside of the vehicle is washed. ● Do not use abrasive cleaners when washing the wheels. ● Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss of pressure or poor seal at the tire bead. CAUTION ● Do not use tire chains on a TEMPORARY USE ONLY spare tire. Tire chains will not fit properly and may cause damage to the vehicle. Maintenance and do-it-yourself 8-41
