A simple measuring device can be used to check the tread depth. If the tread depth has decreased below the minimum, the tires must be replaced.
Check the condition of the tread pattern and its degree of wear. Uneven tire wear indicates poor wheel balance or poor suspension adjustment.
Different forms of tread wear and possible causes
- 1. Low tire pressure
- 2. Incorrect wheel alignment or too much camber
- 3. Uneven wear
- Possible reasons:
- Low tire pressure, poor wheel balance or deformation;
- The steering rods or steering arm are worn out;
- Front suspension components are worn or damaged.
- 4. Too high tire pressure
- 5. Incorrect suspension adjustment
Inspect the tires for cuts, punctures, stuck nails or other sharp objects. If there is an air leak, first check the reliability of the tube valve.
If it is OK, check the tire surface for punctures by applying soapy water to the tire surface. Air leaks will show up as bubbles.
Check your tire pressure regularly using an accurate gauge.
