i know its a f150 forum but does anybody know what the biggest tires i can fit on a stock 1994 f350 is?

 

You could easily fit some 35"x12.5" tires, given that it's a 4x4

 

its a 4x4 drw

 

a dually? they are weird, cuz the rear tires cant touch. your best bet is to hit up a diesel forum,

 

i was thinkin just 2 skinny tires for each side in the back
ill go see what kind of ideas them diesel guys got, thanks

 

You could probably get some 33X9.5's in there

 

i have 33's on the truck now, i just am not sure if 35's will fit, some people tell me they will and some say they wont

 

IMO 35s would be pushing it on a dually. id go 33x9.5 in the rear and 33x12.5 in the front or something, aslong as that dont look weird, iv never dealt with dually's lol. my 4x4 f250 can fit 33s stock so you should be able to get 35s if it wants for the dually rear end...

 

My brother in law drives a 2012 f350 drw with a 4" lift and 35" tires. What he and many other guys do to fit that big of a tire is a 1" wheel spacer between the rear wheels to space them out for the wider tire. I'm guessing you have 16" wheels so go with a 315/75/16.
