I bought a 2013 FX4 with the factory 20's. I put a 2.5 Rough Country leveling kit, and was wondering would 295x65x20 Nitto Trail Graps would fit? Any info would help!

 

Yup.

Look up Nassty's truck. he runs those tires and it looks great!

 

I'm not sure if 295/65/20 (35.5") would fit but 295/60/20 (34.5") will. I think I've only seen one truck with the bigger size.

 

Yeah, 295/65R20s at 35.5 inches tall may be too tight with a 2.5 inch lift. I ran 295/60R20 (34.5 inches tall) Nitto Trails with 2.5 inch lift. My wheel offset was +18mm so I pulled the tire away from the UCAs and had no rubbing on any components, but had to do some minor body trimming.

 

295/60/20 is the size!
