Hey guys just purchased a 05 F350 SD, CC, TD, harley edition I need to know what is The biggest tire I can go without lift. I am thinking of going with 305/55/20 Nitto mud grapplers with a leveling kit, will this work and could I go bigger 315/55/20 without any additional lift fender rud etc. thanks Ron

I have them and they rub in the front at full lock. I think my rims have a 5mm offset.

you can run as big as a 325/60/20 on a factory 20 with no rubbing. no leveling kit required.

revdog you got any pics..i love my stock 20s and want to throw on some cooper discoverer tires, but am unsure about a leveling kit due to i am only about 1.5 inches lower in the front and i have no idea what leveling kit to buy

yhese are the only two i have with 325's on it. im running 35's right now. the 325's were a little bigger. icon seems to make the best leveling kit. if you have a 250 it raises front and rear.
