I have a 2006 FX4 with the stock 18 inch FX4 wheels with a leveling kit. I was wondering what is the biggest tire i can fit on the stock wheels?If you guys have any pics with that set up please post them. Please mention what kind of tires you have.

 

Bigfoot, the largest size without too many rubbing problems would be a 305x65x18 BFG All Terrain. This is right under 34" in diameter. Some members including myself try to run 35's but you will have rubbing problems. I still may get a set and put on my 18" Lariat wheels. Only thing bad is that they just came out and dey ain't cheap! More and more members are going with this size.

 

I myself have 325/60R18 on stock wheels. 2 inch front lift 1 1/2 inch rear lift.
Little bit of rubbing on full lock.

 

runnign 35x12.5R18's on stock. i rub my upper control arm, lower control arm if i turn to full lock.

 

What kind of tires are you guys running when you put the 35x12.50s on stock wheels?
