CHECKING TIRE PRESSURE
32X002a
The recommended cold tire pressures, tire size and the vehicle
capacity weight are given on the label.
You should check the tire pressures every two weeks, or at least once
a month. And don’t forget the spare! The pressure for the spare tire
should be 220 kPa (2.2 kgf/cm
2 or bar, 32 psi). Incorrect tire pressure
can reduce tire life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling, reduced
fuel economy, and the possibility of blowouts from overheated tires.
Also, low tire pressure can cause poor sealing of the tire bead. If the
tire pressure is excessively low, there is the possibility of wheel
deformation and/or tire separation. So keep your tire pressures at the
proper level. If a tire needs frequent refilling, have it checked by
your Lexus dealer.
High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater possibility
of tire damage from road hazards.
The following instructions for checking tire pressure should be
observed:
D
The pressure should be checked only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not
been driven for more than 1.5 km or 1 mile since, you will get an
accurate cold tire pressure reading.
D
Always use a tire pressure gauge. The appearance of the tire can
be misleading. Besides, tire pressures that are even just a few
pounds off can degrade handling and ride.
D
Do not bleed or reduce tire pressure after driving. It is normal
for the tire pressure to be higher after driving.
D
Never exceed the vehicle capacity weight. The passengers and
luggage weight should be located so that the vehicle is balanced.
D
Be sure to reinstall the tire valve caps. Without the valve caps,
dirt or moisture could get into the valve core and cause air
leakage. If the caps have been lost, have new ones put on as soon
as possible.
