How does incorrect tire pressure affect a vehicle?

Incorrect tire pressure significantly impacts vehicle performance, primarily by leading to poor handling. When tires are either over-inflated or under-inflated, they cannot maintain optimal contact with the road surface. This results in reduced traction and stability, which can compromise the vehicle's ability to turn effectively and respond predictably to driver inputs.

For instance, under-inflated tires tend to have a larger contact patch, which can cause excessive flexing and overheating, ultimately degrading performance and increasing the likelihood of a blowout. In contrast, over-inflated tires may reduce the contact patch, leading to a harsher ride and diminished grip, especially in wet conditions. Both scenarios result in poorer handling characteristics, increasing the risk of losing control of the vehicle.

Effective tire pressure is essential not just for handling but also for overall safety, fuel efficiency, and longevity of the tires. Properly inflated tires enable the vehicle to perform optimally, enhancing driver confidence and safety while on the road.
