Appropriate tyre pressure can prolong the service life of tyres, and at the same time improve the driving comfort, use economy and handling stability of vehicles.
When the tyre pressure is too low, it will aggravate tyre wear, which will greatly affect the handling stability and use economy of vehicles, and increase the danger of tyre failure.
Excessive tyre pressure will lead to unstable driving and uneven tyre wear, thus reducing the service life of tyres.
Check the tyre pressure at least once a month, after driving on rough roads or before driving long distances.
When checking tyre pressure, it must be in a cold tyre state. Cold tyre means that the vehicle has not driven for at least 3 hours or has not driven more than 1.6 km.
For cold tyre pressure standards, please refer to the tyre pressure label located below the driver's door pillar.
Never deflate the tyre in a hot state. Incorrect tyre pressure can lead to unusual tyre wear and overheating. These may affect safety:
- Risk of bursting or tread separation.
- The tyre pressure depends on the load and vehicle speed, and the tyre pressure is adjusted according to the use conditions.
- Note that a missing or untightened valve cap may make the tyre less airtight and cause pressure loss.
- Always use the same valve cap as the original and tighten it completely.
The tyre pressure gauge can be used to check the tyre pressure when the tyre is cold. Remove the valve cap from the tyre valve and check the valve for air leakage by using the soapy water.
Add washing liquid to water, smear on valve to check for bubbles. Bubbles mean air leak.
After the tyre barometre is installed on the valve, the tyre pressure will be displayed on the barometre.
Check and adjust the tyre pressure until it meets the standard value.
After the inspection, be sure to install the valve cap back to the valve.
After the vehicle has been running for a period of time, the tyre pressure will increase by 0.2 ~ 0.5 bar. Do not adjust the tyre pressure at this time, otherwise the tyre pressure will be lower than the standard value in the cold tyre state.
If the tyre pressure is obviously insufficient, the vehicle will continue to run at high speed, and the tyre will be deformed constantly, which will easily lead to overheating of the tyre and burst of the tyre.
