The standard tire is inflated to about 30 to 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi.

Is it bad to overinflate tires?

Both under and, over-inflating a tire can actually be detrimental to the performance of a vehicle and to the life of a tire. Over-inflating tires causes the sidewalls and tread of the tire to become harder than normal. This can reduce the traction and performance of the tire, as well as cause uneven tire wear.

What happens if tires are overinflated?

When overinflated, your tires round out on the tread section, causing the center to wear significantly faster than the outer edges. Your tires might only last half the life they normally would. Overinflation can cause loss of traction.

What happens if your tire pressure is too high?

Excessive air pressure can also distort the shape of the tire, leading to decreased traction and increased wear and tear down the center of the tire.
