Checking tyre pressure is very important. Keep your tyre pressure at the proper
level. You should check the tyre pressures every two weeks, or at least once a month.
Don’t forget the spare!
Make it safe, Make it last!
Incorrect tyre pressure can reduce tyre life and make your vehicle less safe to
- Low tyre pressure results in excessive wear, poor handling, reduced fuel economy
and the possibility blowouts from overheated tyres.
- Low tyre pressure can also cause poor sealing of the tyre.
- If the tyre pressure is excessively low, there is the possibility of wheel deformation
and/or tyre separation.
- High tyre pressure produces a harsh ride, handling problems, excessive wear at the
centre of the tyre tread and a greater possibility of tyre damage from road hazards.
- If a tyre frequently needs refilling, have it checked by your Toyota dealer.
Follow these steps when checking tyre pressure:
- Cool down time!
Only check the pressure when the tyres are cold.
If your vehicle has been parked for at least 3 hours and has not been driven more
than 1.5 km since, you will get an accurate cold tyre pressure reading.
- Measure by measure!
Always use a tyre pressure gauge. The appearance of a tyre can be misleading. Tyre
pressures that are even just a few kilopascal out can degrade handling and ride.
- High Pressure System!
Do not bleed or reduce tyre pressure after driving if you notice the pressure is
higher. It is, in fact, normal for the tyre pressure to be higher after driving.
- Put a lid on it!
Be sure to reinstall the tyre inflation valve cap. 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.
Checking and Replacing Tyres – The Basics
The tyres on your Toyota have built-in tread wear indicators to help you know when
the tyres need replacement. When checking the tyre tread for the tread wear indicators,
replace the tyres if the:
- Tread depth is worn to 1.6 mm or less,
- Indicators in two or more adjacent grooves are visible,
NOTE: The less the tread, the higher the risk of skidding.
CUTS, SPLITS AND CRACKS
Check your tyres regularly for damage such as cuts, splits and cracks. If any damage
is found, consult with a technician and have the tyre repaired or replaced.
Even if the damage does not appear serious, a qualified technician should examine
the damage. Objects, which have penetrated the tyre, may have caused internal damage.
Any tyres over six years old must be checked by a qualified
technician even if damage is not obvious. Tyres deteriorate with age even if they
have never or seldom been used. This also applies to the spare tyre and tyres stored
for future use.
REPLACING YOUR TYRES
When replacing a tyre, use only the same size and construction as originally installed
and with the same or greater load capacity. Using any other size or type of tyre
may seriously affect handling, ride, speedometer and odometer calibration, ground
clearance and clearance between the body and tyres.
- Do not mix radial or cross ply tyres on your vehicle. It can cause dangerous handling
characteristics, resulting in loss of control.
- Do not use tyres or wheels other than the manufacture’s recommended size.
