I just purchased Helo Maxx 6 Wheels (18x9R18 backspace 5.39). I was going to purchase the Nitto Terra Grappler in 285/65R18 but I found a set of BFG AT KOs in 305/65R18 for a great price. Will these be to large for a 2007 F150 Ext Cab 4X4 (not leveled or lifted). I dont mind if I have to trim a little plastic, I just dont want and metal rubbing. Thanks.

 

You will be fine if you install a leveling kit. Not sure if that combo will fit without one.

 

I was thinking of the same set up what kind of prices are you getting?
