proper tire pressure - 225/75-15 for normal use?

I've got stock wheels and 225/75-15 (i think that's correct) basically stock tires on my 99 Cherokee.

What should be the normal tire pressure for everyday use on the street? All 4 are reading around 22lbs right now.

thanks

i believe it is 30psi. You don't go by the tire's MAX pressure. The tire pressure should be inside the door jamb or manual of your XJ

best thing to do is go to the tire manufacturer's site look for your tire and it usually tells you the proper psi.

Tire manufacturer recommended pressure not always right look in the drivers side door jamb as stated before. The reason is the tire maker does not account for vehicle weight and weight distribution. Just never go over max tire pressure on tire. Most of the time lower pressure is for better ride in that case you can get closer or at tire max pressure and get more mpg but sometimes pressure affects handling and wear. I had a link that told you how to find best tire pressure by checking it when cold then once warmed up after driving I think there was suppose to be 1 psi difference. But don't quot me on that.

It's written on the tire. Once you find it, subtract about 6-8psi depending on the ride and handeling you want. This also allows for the 2-3psi you'll gain when the tires get warm.
