At what PSI will a tire explode?

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 36 psi too high?

Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure ” of 33 psi, Gary.

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.
