I have a 04 FX4 with the 18" factory wheels. I would like to put larger tires on the factory wheels. I use this truck to pull my Mobius LSV which weighs about 4,000 pounds with a single axle trailer. I am really new to this and need some help. By the way, once a man and twice a boy is true. I am working on the boy side again.

 

There's a member here who put 285/65-18 (basically a 33x11.50-18) BFG AT KO's on his 04. THey looked really good.
