I have recently got a 2009 F150 4x4 {4}door. I have had a 2inch front and 1inch back level kit put on it. {Rough Country}. I am trying to find out what is the biggest tire I can put on it without having to trim or rub. I am running 285/70/17 AT right now. I have been told 295, 305, and 315. I am confused on who is correct.

 

If you're using the stock 17x7.5 wheels the 295x70x17 (33.5x12) would be a good fit...the 305 and 315's would be too wide for the wheel.

 

Thank you, they are the stock 17inc wheels.
