Sticker on truck says 39lbs all around. I have the 20" goodyear rsa's. Do all the 2014 rams with 20" wheels have the same suggested tire pressure? I guess I'm asking because the truck does ride a bit better with a little less pressure. Also my last vehicle, GMC Yukon with 20in wheels suggested 32lbs all around. Not a pick-up truck I know but still pretty heavy.
