Strange, the recommended pressure on my truck are only 39psi and I think it weighs a good 3,000lbs more than my Cobra.. Oh, we use infrared heat guns these days...

So if you use 25# expect the tire to roll off the rim in aggressive driving....

That is hilarious, I can guarantee you that there is one other person on Club Cobra who car pulls as many G's as mine does and I run between 19-23psi front and 18-22psi rear on 200 treadwear tires and I've yet to have one come off the rim...
