Maintenance and service
NOTE
The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
2
kgf/cm ) when the tire becomes warm.
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).
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally.
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is re-
sponsive. Rolling resistance is low, so fuel
consumption is also lower.
Abnormally low tire pressure (tread
worn at shoulders)
B00050
Rolling resistance is high, so fuel con-
sumption is also higher.
