# FAQ: How To Check Air Pressure In Car Tires?

## How do I check my tire pressure without a gauge?

Push your hand down onto the tire. If the tire feels soft and squishy, the tire pressure is low. If the tire feels rock hard, meaning you are unable to push down on the tire at all, then it is overinflated. If the tire feels too low, pump some air into it while keeping your hand on it.

## How do I know if my tires have enough air?

Check to see when you have enough air pressure in the tires by releasing the inflation lever. The gauge on the hose fitting will show if you have approximately enough air pressure. You can check it again later with your own gauge. At this point, it is better to slightly overinflate the tire.

## Is 40 psi good tire pressure?

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. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.

## 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.

## What the lowest tire pressure you can 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 is the best tire pressure?

Since maintaining your tires is so important to your safety and your car’s overall performance, it’s important to know what tire pressure is right for your vehicle. Air pressure in tires is measured in pounds per square inch, or PSI; usually, the recommended pressure ranges between 30 and 35 PSI.

## When should you put air in your tires?

Inflate your tires when they are cold. If you ‘ve driven more than a couple miles, you ‘ll want to wait until they are cold. The best time to refill your tires is first thing in the morning. You can usually set the desired PSI level on the machine at the gas station (probably around 30-35 PSI).

## Why do dealers overinflate tires?

Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.

## What happens if you put too much air in your tires?

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. It means center tread wear, an uncomfortable ride, and increased risk for a blowout.

## What happens if you don’t put air in your tires?

Inadequate tire inflation can shorten the life of your car’s tires, negatively affect your vehicle’s performance, and maybe even cause a tire to fail. When air pressure gets too low, the tire’s sidewalls flex more, and heat builds up within the tire.

## 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. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.

## Is 50 psi a good tire pressure?

Every tire has a rated maximum inflation pressure. Often it will be found in small print around the rim edge of the sidewall. This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch).

## 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.
