Compromised Safety There are a variety of issues that can occur if you drive on overinflated tires. Most seriously, overinflated tires are at greater risk for a blowout. A tire blowout can cause you to lose control of your vehicle and negatively affect braking distance, endangering yourself and others on the road.

Are all tires supposed to be 35 psi?

Most passenger cars will recommend 32 to 35 psi in the tires when they’re cold. The reason you check them cold is that as tires roll along the road, friction between them and the road generates heat, increasing tire pressure.

Can you put air in a tire without a gauge?

Yes, you can put air in your tires without a pressure gauge, because a pressure gauge is a pressure gauge, it does not inflate the tire. Pressure gauges are instruments used to measure the pressure of a fluid, in this case, air, in a closed circuit.

What should the tire pressure be in the winter?

For the air inside the tire to occupy the same volume (i.e., the tire has the same roundness) between summer (86 F) and winter (32 F), the tire pressure in winter should be about 10\% higher. If the pressure in summer is 32 psi, then in winter it should be about 35 psi.
