How Does Tire Pressure Impact Flat Spot Formation?
Tire pressure significantly impacts flat spot formation. Flat spots occur when a tire does not rotate for a lengthy period and the weight of the vehicle compresses the tire’s contact patch against the ground. When tire pressure is too low, the tire’s sidewalls flex more than they should. This increased flex can enhance the pressure on specific areas of the tire, leading to uneven wear and the development of flat spots. High tire pressure can also cause issues. Excessive pressure makes the tire rigid, reducing its ability to conform to the road surface. This rigidity can result in more pronounced flat spots during periods of vehicle inactivity. Therefore, maintaining proper tire pressure is crucial. It prevents tire deformation and ensures even contact with the road. Regularly checking and adjusting tire pressure helps avoid the formation of flat spots and prolongs tire life.
Can Extended Parking Contribute to Flat Spots on Tires?
Yes, extended parking can contribute to flat spots on tires. When a vehicle remains stationary for an extended period, the weight of the vehicle can cause the tire to deform slightly.
