and add the appropriate air pressure when you get
to the pump. It is normal for tires to heat up and
the air pressure inside to go up as you drive. Never
"bleed" or reduce air pressure when tires are hot.
2. Remove the cap from the valve on one tire, then
firmly press the tire gauge onto the valve.
3. Add air to reach the recommended air pressure
Note: If you overfill the tire, release air by pushing
on the metal stem in the center of the valve. Then
recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the
spare.
Note: Some spare tires require higher inflation
pressure than the other tires.
6. Visually inspect the tires to make sure there are
no nails or other objects embedded that could poke
a hole in the tire and cause an air leak.
7. Check the sidewalls to make sure there are no
gouges, cuts, bulges or other irregularities.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause
the front end of your vehicle to become misaligned
or damage to your tires. If your vehicle seems to pull
to one side, vibrate or shake when you're driving,
the wheels may be out of alignment. Have a qualified
technician at a reputable repair facility check the
wheel alignment periodically.
Wheel misalignment in the front or the rear can
cause uneven and rapid treadwear of your tires and
should be corrected by a qualified technician at a
reputable repair facility. Front wheel drive (FWD)
vehicles, and those with independent front
suspension require alignment of all four wheels.
The tires should also be balanced periodically. An
unbalanced tire and wheel assembly may result in
irregular tire wear.
