What does inflate to 33 PSI mean?

For every change of 10 degrees in the outside temperature, tire pressure changes about 1 psi. So if you fill your tires to 33 psi when it’s 75 degrees out, and it drops to 25 degrees at night, your tires will be at 28 psi. That’s too low.

What is TYRE pressure gauge used for?

A tyre pressure gauge is used to measure the pressure of the tyres of a car, motorbike or any vehicle that uses inflated tyres. Simply using your eyes to estimate tyre pressure isn’t accurate and could lead to misleading results. Gauges offer accurate and reliable readings and come in both standard or digital formats.

Is 30 PSI too low to drive on?

If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout.

What pressure should I fill my car tires to?

32 to 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.
