Relationship between tire pressure and power cycle

Power cycling refers to the phenomenon of tire slippage and rotation caused by the different rolling radii of tires on different axles of a vehicle, resulting in power loss. Tire pressure affects tire deformation, and the magnitude of tire deformation affects the rolling radius, thus affecting the vehicle's speed. For two-axle vehicles, tire pressure must be selected according to the front and rear axle loads to ensure that the tires have the same rolling radius and avoid power cycling.

The relationship between tire pressure and vehicle braking performance

A car's braking force depends primarily on the braking force of the brakes, but it is also limited by the road surface adhesion. Therefore, sufficient braking force can only be achieved when the car has adequate braking force from the brakes and the road surface provides high adhesion. Appropriately reducing tire pressure increases tire deformation, enlarges the contact area between the tire and the road surface, thereby improving adhesion and ensuring good braking performance.

The relationship between tire pressure and vehicle passability

A car's passability depends on many factors, among which tires are a crucial one, including tire tread pattern, diameter, and tire pressure. For the same tire, the required tire pressure varies depending on the road surface. On good roads, try to keep the tire pressure at the standard value, while on soft roads, try to keep the tire pressure lower; otherwise, the tires are prone to slipping in place.

Tire pressure is a crucial factor affecting tire lifespan and fuel economy. Inappropriate tire pressure can cause power cycling, leading to increased tire wear and reduced lifespan. Considering the impact on performance, choosing the correct tire pressure is essential to extend tire life and improve fuel economy.
