i keep kicking around the idea of 19.5s and am currently trying to figgure out a solution that wolnt cost me 4k. i am wondering if someone could put 235/85r16 on the rear, and 265/75r16 up front.... they have an overall diameter of 31.90 and 31.74.... as far as 4wd goes it would work. but will a 265 mount on a stock, or aftermarket rim? it reccommends a 7" rim... i see guys running 285 and bigger on the pyo rims so i suppose it would work? what im trying to do is put a little more tread up front to float the weight of the beast under the hood.... tends to drop like an anchor in the mud...
