Proper Use of Tires
"Pressure is the life of a tire." Maintaining correct inflation pressure is crucial for maximizing tire lifespan and performance. Here are some important tips:
1. Wait until the tire has cooled before inflating after driving, as temperature increases can affect pressure.
2. Check valve stems regularly. If they are not flat or have defects, it may lead to improper inflation.
3. Ensure the air used for inflation is clean and free from moisture or oil, which can damage the inner tube.
4. Do not overinflate the tire, as excessive pressure can cause internal damage and reduce tire life.
5. Handle the valve carefully—clean the valve before inflating and check for leaks by looking for bubbles. Tighten the valve cap to prevent dirt from entering.
6. Always use a calibrated pressure gauge to measure tire pressure, rather than relying on visual inspection or experience.
7. The pressure reading on the air compressor may not match the actual tire pressure.
8. Even when overloaded, do not inflate beyond the recommended pressure. Overinflation increases the risk of punctures without improving performance.
