Contact Pirelli or the dealer you bought them from, they should know...clickart said:I got Pirelli 305/40/22 on an 02 Escalade. I would like to know the correct psi for these kind of tires. I want the best psi 22" so the tires can last long. Thanks!!!
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.lux hauler said:It should be imprinted on the sidewall of the tire. It should also be in the original paper-work (if you bought them new).
GMike said: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.
