    Contact Pirelli or the dealer you bought them from, they should know...

    It should be imprinted on the sidewall of the tire. It should also be in the original paper-work (if you bought them new).

    Whatever it says on the tire with my 23's i I belive it is written 45 PSI on the tire but that is the MAX load. I usually keep my tires either 3-5 underneath the max load it just depends on the weather. If I were you just keep it 3 under whatever it says on the tire.

    Cool Re: What is the correct PSI for 22" Rims?

    Man, I don't know about that. Personal experience and logic would suggest that kind of tire pressure (40+) in low profile 22" tires will give you a rock hard ride, beating up the vehicle, suspension and driver.

    I just added 20" 285/50R20 wheels and tires and I'm planning of going with 30-32lbs and adjust up from there. I think with 50 series tires I have plenty enough side wall to give decent ride and still protect the wheels and rims from potholes.

    Inflate the tires to the pressure the manufacturer recommends!!
    Tires that are run under-inflated can build more heat than the tire is designed for which could cause them to fail. It also causes premature wear, poor traction and ill handling.

    Question Re: What is the correct PSI for 22" Rims?

    Which manufacturer? Cadillac (30 PSI), Wheel Mfr, or Tire Mfr? No body agrees at all. Common rule of thumb is to go with PSi the car mafr suggests. This is based on the vehicle weight and suspension. So, when the tire and wheel size change, how will that effect the PSI? I ended up increasing the PSI in the 285/50 R20 Goodyear GTII's to 36 rear, and 34.5 front. It seams to offer good ride, handling, and wheel protection. But, I am keeping an eye out for unusual tread pattern wear.

    All I'm saying is you don't want to "Cold" inflate to anywhere near the tires Max pressure. The tire heats up as its driven and can easily exceed the Max rating and cause a blowout. If I find and optimal pressure for 20" tires, I post it here.

    GMike,I run 36 front and back with my 285/50/20's. Been doing that since the first day and the tires are wearing nice.

    They say to run 90% of the max pressure. That should calculate out to 45 psi. I have 23's (Pirelli Scorpions) and run 43 psi. (Max 50 psi)
