Tire (Pressure and Tread Wear)
Repair Procedures
Inspection
Check the tire pressure.
Tire Pressure
Tire Front Rear 205/65 R16 250 kPa (35 psi) 250 kPa (35 psi) 215/55 R17 250 kPa (35 psi) 250 kPa (35 psi) 215/60 R16 250 kPa (35 psi) 250 kPa (35 psi) 235/45 R18 250 kPa (35 psi) 250 kPa (35 psi)
Tire Rotation
Pull and Wander Test
If the steering pulls to one side, rotate the tires according to the following wheel rotation order.
Swap the front right and front left tires, then perform a road test to confirm vehicle stability.

If the steering pulls in the opposite direction, rotate the front and rear tires, then perform the road test again.

If the steering continues to pull to the same side, rotate the front right tire and perform the road test again.

If the steering continues to pull to one side, replace the front wheels with new ones.

Tire Wear
Measure the tire tread depth.
Tread depth [limit]: 1.6 mm (0.0630 in.)
If the remaining tread depth (A) is less than the limit, replace the tire.
