How do I know my optimum tire pressure?

The first place to look for the correct air pressure for your specific tires is your vehicle owner’s manual. Correct air pressure should also be listed on the tire placard attached to the vehicle door edge, doorpost, glove box door or fuel door.

Do all tires require the same air pressure?

Most cars all tires have the same pressure. It is what the manufacturer specifies, but the tires on the same axle should have the same pressure. There is a tire pressure placard on the drivers door or jamb which specifies the tire pressure.

Should front tires have more pressure?

In short, they’re not. Tyre pressures are normally higher in the front than the rear, to compensate for the extra weight of the engine and transmission, especially on front-wheel-drive cars. Some makers (BMW is one) run lower pressures in the front, mainly to improve tyre wear on rear-wheel-drive cars.

What information does the tire placard have?

The tire information placard will tell you the vehicle’s weight capacity, the OE (Original Equipment) tire sizes (including the spare tire), and the recommended inflation pressures for the tires.

What tire pressure should I run in 35 tires?

For a 35″ tire, on a Wrangler, the pressure should be around 24 – 26.

Why do bigger tires require less psi?

In an effort to explain optimal tire pressure in the simplest terms, think of it this way: the load of any vehicle is supported by the amount of air in the tires. Therefore, a larger tire needs less pressure than a smaller tire to carry the same vehicle weight.

What tire pressure should I run on my 37 inch tires?

It is recommended that it alarms at 4 psi under what you normally run the tire at. I run my 37″ GY MT/R- Kevlar’s at 30 psi with the TPMS alarm set to 25 psi. Thanks.

Why do wider tires need less pressure?

Since the tire gets wider with a wider rim, we increase the dimeter in our pressure equation above. This results in a lower tire pressure for a wider rim with the same size tire.
