TIRE AND WHEEL
INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and for the proper inflation pres-
sure.
Cold tire inflation pressure:
2JZ-GE
Tire sizeFront
kPa (kgf/cm2, psi)
Rear
kPa (kgf/cm2, psi)
225/50R16 92V230 (2.3, 33)-
245/45R16 94V-230 (2.3, 33)
2JZ-GTE
Tire sizeFront
kPa (kgf/cm2, psi)
Rear
kPa (kgf/cm2, psi)
235/45ZR17230 (2.3, 33)-
255/40ZR17-230 (2.3, 33)
(b) Check the tire runout.
Tire runout: 1.4 mm (0.055 in.) or less
2. INSPECT WHEEL BALANCE
(a) Check and adjust the Off-the-car balance.
(b) If necessary, check and adjust the On-the-car balance.
Imbalance after adjustment: 5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the axle bearing backlash.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORKS PROPERLY
Check for oil leak.
Check mounting bushings for wear.
Check front and rear of the vehicle for bounce.
