CAUTION The vehicle must not be driven with wheels of different dimensions or with a spare tire other than the one that came with the vehicle. The use of different size wheels can seriously damage your vehicle's transmission. Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the hub caps. Locking wheel bolts can be used on both aluminum and steel wheels. If hub caps are used on steel wheels, the locking wheel bolt should be mounted in the hole as far from the tire's inflation valve as possible. It would otherwise not be possible to mount the hub cap on the wheel. 172 07 Wheels and tires Changing wheels 1.
