Air Pressue 22's

[CLAYMAN]

For everyone running on 22's. What tire pressure are you using. By the way, my tires are 295/40.

You should run what your tire, temperature, load, and road conditions dictate. For me, I have run as low as 20psi in my snow tires and as high as 40psi in a set of Pilot Sport 4S when they were all heated up running canyons. Tire pressure should be adjusted for towing and for temperature and your starting point will be dependent upon the manufacturer of your tire and what they recommend. For example, I have found with Contis that they love to run at much higher psi than the sidewall recommends. That is the real answer.

The set it and forget it answer? For "MOST" street tires load rated for our vehicles, keep em at 35psi all the time and you should be fine. If you notice uneven wear, increase or decrease pressure to compensate appropriately.

Buy some chalk that will show up and leave good marks on your tires. Air the tires up to 35 psi. Drive the car until the tires are at normal operating temps. Put a chalk mark across the tread of each tire. Drive in a straight line for 50 to 100 feet. Check the chalk marks. If the chalk is worn off in the center, let some air out of the tires. If it's worn on off on the inside and outside, add air. Keep doing this until you have an even wear pattern across the tire tread. These are the pressures you should be running. Note the front and rear pressures will probably be different as most vehicles do not have a 50/50, front to rear weight balance.

Note these pressures will, change depending on seasonal temperatures and load of the vehicle. If you have hot summers and cold winters, use this procedure at the beginning of each season.

I run 32psi in mine cold. They warm up to about 35psi

I also run 32 psi, the door plate says 33 psi but it gets pretty hot here in Sacramento!
