Quick Answer: What Psi For Pirelli Full Size Spare In 2012 Vw Jetta?

What PSI should my spare tire be?

Unlike your four regular tires, compact spare tires typically should be inflated to around 60 pounds per square inch; PSI far short of that level could fail and damage the wheel, as well.

Why do spare tires have higher PSI?

According to TireRack, donut spares have a higher air pressure because of their smaller dimensions. That’s right, a donut spare has about half the contact surface of a full-size tire. To compensate for the reduced surface area, the air pressure in the tires needs to be higher than a full-sized tire.

Does the spare tire have a pressure sensor?

Most customers are unaware that their spare tire also comes equipped with a tire pressure monitor, and the TPMS is only installed on full-sized spares, not donut spares. The light may also turn on when a tire is punctured, warning you of a flat before it happens.

Is 60 psi too high for tires?

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.

Roadshow: Temporary spare tires can often lose air pressure – The Mercury News.

Can you use a different size tire as a spare?

How much PSI is in a donut?

Check your donut tire pressure: The safe air pressure recommended for the donut tire is 60 pounds per square inch (psi). Since the donut tire sits for a while without being inspected, it is a good idea to check the air once you put the tire on your car.

How often should you check your spare tire pressure?

We recommend that you check your spare (and your other tires) once a month. When inspecting your spare, be sure to check for proper air pressure, signs of aging, damage, or excessive wear.

Is it safe to drive with tire pressure sensor fault?

Is 50 psi too much?

The best PSI for a tire depends on the tire. For my car, 50 PSI would be way too high. Having either front tire of your car blow out at highway speeds would be very dangerous and would be very likely to result in a crash. The recommended inflation level for my car is much lower than this, and is closer to 35 PSI.

Is 40 psi bad for tires?

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 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.
