Looking at getting new tires pretty soon on my 2010 F150 Supercrew 4X4. First truck stats. Leveled 2", Stock "chrome package" wheels, running 5Star's 93 octane tune with 3.55's. I have narrowed it down between 2. Goodyear Duratrac's ( 275/70/18) & BFG A/T (305/65/18). I am running Goodyear AT/S 275/65/18 now. I have run the same size BFG's before on an '05 FX4 with 3.73's & it seemed to do rather well. With the BFG being 30MM wider and my stock 3.55's it may be another story I am thinking.

 

im running 305/60/20s with 3.55 gears.....I was also worried about performance and towing but just made a 1500 mile trip pulling my 21' bassboat and truck did very well..avg. around 14mpg pulling boat...

 

The BFG's will look better on your truck but the Duratracs being a smaller diameter and narrower tire may give you better performance and mileage. Also the BFG's will probably last longer too, the TA/KO's hard hard to wear out.
