What would be the biggest tire i can put on my truck. Its 4wd by the way.

 

Anyone? I am going to buy these tomorrow. I asked the dealer and he said he did not know, I want 31/10.50/15 but the guy said it would be a test fit and he would not warranty them.

 

i have a '96 f-150 that is a 4x4 and i run a 31x10.5 on a 15 inch wheel. it fits fine. i know a couple people that spaced their bumpers further with washers to allow for more room and also trimmed the valance. you should be fine. good luck

 

get some pics up of the new tires
