I have a 1982 chevy 1/2 4x4 i got 33's on it right now and just got done putting a Tuff Country 6 inch lift on it and theres a huge gap the 33's kinda look small could anyone tell me whats the bigest size i can rund without triming fenders or anything.

without any interference with the fenders during flexing, a 36" tire on a 10" wide rim with at least 3.5" of back spacing. You could probably run 37-38s on a narrower(8") rim. if you go with 12-14" wide rims I'd say keep it at 35". Of course this is all subjective and I'd recommend test fitting if possible before buying, I have a neighbor running 35s BFGS w/ 6" of lift and he had 38.5s TSLs that would occasionally rub.

Pretty much.Most tires you`ll find will be 35"radials.There`s a few 12-12.50 x36 tires out there.Basically,you can run these tires on 10"rims which will all be somewhere around 4" backspace.
