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 drive.
- 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 Lexus 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.
