Originally I was wanting to run 38 I think I have talked myself into running 36", However I want to run a 13.50 Or a 14.50 tire I like a little wider look on my stance I figured with 8 inches I would have Mcclerge issues at all if I can get by with 6 inches I am okay with that?
Just so you know there are several people on here who have succesfully run a 36" tall tire on a stock truck. Usually not so wide but I have done a 37x14.50 on a stock truck. Took quite a bit of trimming but go slow and be careful and it can look really good.
36x12.50 on a stock truck is actually super easy.
So a 4" lift and some 36x14.50s would still be pretty easy to do. Just don't go crazy with the sawzall when trimming and it can look pretty darn good.
