wondering what the biggest tires/rims that I can run on a 02' F-350 six-pac without a lift kit???

i don't know about an f-350 but i've put 33's with 17" rims on an f-150 with no tire rub. but i don't think it would have worked off-road. since you have a much bigger truck, you might get 36's but that will be pushing it.

you wont get 36's put on 33's theyll scrape on SHARP turns but you can always notch out the bumper/fender but 36's you wont fit without lifting
