When a tire is under-inflated or over-inflated, it loses stability, negatively affecting handling, cornering, and stopping. Eventually the tire will also start to wear unevenly. Under-inflated tires tend to show wear on the outside edges of the tread, while over-inflated tires show wear down the middle of the tread.

How does over-inflation affect tire tread wear?

Tread Wear

Over- and under-inflation can significantly decrease the life of your tires. Over-inflation causes the center section of the tread to balloon outward. This puts more weight on the center of the tire. This extra weight causes the center of the tire wears quickly.

What is the proper tire inflation?

Air pressure in tires is measured in pounds per square inch, or PSI; usually, the recommended pressure ranges between 30 and 35 PSI. To learn what your tire pressure should be, look for your manufacturer's recommendation, which is printed on a label inside your car.

Should all 4 tires be the same PSI?

Also can lead to vehicle instability problems, since the tires are designed to flex, but uneven tire pressures causes the tires to flex differently. Tires on the same axle, like both fronts, have the same recommended tire pressure and it is not unusual to see different recommended pressures from front to rear.

Do you go by the tire pressure on the tire or the car?

the PSI is by the car. The PSI on the tire is the max PSI you can put into the tire safely. The tire can go on many different cars so the tire PSI isn't car specific. The PSI given on the door sticker, and owner's manual is specific for the car and that's what you go by.

Is it bad to slightly over inflate your tires?

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. ... Overly-inflated tires will also cause the vehicle to have a harsher, more unstable ride than properly inflated ones.

Why do tire shops over inflate new tires?

The reason mechanics and car dealerships overinflate tires is because theyre lazy. Someone is going to more easily notice an underinflated tire. Rather than checking the tire pressure on their cars all the time they just overinflate them all.

Is 40 psi too much for tires?

1. What's The Recommended Tire Pressure For My Car? ... Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.

Is 50 psi too much for tires?

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 30 psi enough for tires?

Being low on pressure doesn't hurt the tire or the wheel at all, unless they get very low, like 10 PSI. Also, you should check your owner's manual to see what the correct tire pressure setting is. 30 PSI is a safe bet, although the odds of your car specifying exactly 30 are rare.
