NOTE
D The air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kg/cm
2 ) when the tire
becomes warm.
D The tires are considered cold when the vehicle
has been parked for at least three hours or has
been driven less than one mile (1.6 km).
WARNING
Do not let air out of warm tires to adjust
pressrue. Doing so will result in low tire pres-
sure.
Incorrect tire pressures detract from controllability
and ride comfort, and they cause the tires to wear
abnormally.
D Correct tire pressure (tread worn evenly)
Roadholding is good, and steering is responsive.
Rolling resistance is low, so fuel consumption is
also lower.
