It's the misconception of the max press on the sidewall being mistaken for a recommendation that I disagree with...
Well I'll say it then. It's dangerous!
Example: max recommended pressure on my TerraGrapplers is 50psi. At that pressure there would be about 42% less rubber in contact with the road than what Isuzu intended, which will significantly increase stopping distance - and reduce lateral grip as well. Unless you're hauling a lot of weight, for safety's sake you might want to air down a little! Who knows - it might keep you from rear-ending somebody on the freeway someday.And BTW, 29psi is specified as cold - so pressure increase according to the Ideal Gas Law is already accounted for.
