Re: front/rear tire size

I am running 275X40X20 fronts and 295X40X20 rears. 20x8.5" front rims 20X10.5" rear rims. Both with 5-1/8" of back spacing....... Fender well openings are pretty well filled.......

That gives me a Dia 28.70” in front and a Dia. of 29.3" in the rear.

Re: front/rear tire size

Depending on whether you want an offset setup or not, you're looking for about 29" diameter (28" front for offset). You're less than 26" right now. 275/55-17 would get you there.

Re: front/rear tire size

I have 235 55 17 fronts on mine and 275 55 17 on the back. That's a 27" front tire and 29" rear tire and fills them well I think.
