Ok, so heres the poop.. My Pal currently has ST185/75D 13 (1660 lbs per tire) tires on it, I am having a hell of a time trying to find some place (other then a stealership) to buy replacements. Most of the ones I have found are only good for load range "C", my pup need's "D". I have found several places with ST185/80D 14 Which are also load range "C" but have a higher rating of 1660 lbs plus . These come with rims as a complete assembly so I'd have to replace all 3 wheels. My question is will the 14" assemblies fit on the axle (hub) ???
