Gas Mileage/Tire Upgrade
 

I have a 05 F-150 4x4 with 18"rockstar rims, 2.5" leveling kit on the front, and 285/60r18 Nitto terra grapplers right now. I want to know how much bigger i can go without rubbing, having to put a lift or doing any modifications. I've been looking between the Toyo Open Country MT's....Mickey Thompson Baja MTZ. Any help is appreciated on tire choice as well. Also how big of a decrease in MPG will I be looking at?

I have 35/12.5/r18 nitto trails on stock rims and suspension and they only rub a little at full lock, I also have 3.55 gears( I know that's bad). I don't think I lost alot in mpg maybe 3 miles?

Awesome that's the info I needed man. You have any thoughts about my tire choices? Or know of anyone that may have had either ? I love my Nittos but just want to change it up and go for a meaner look. Any other tire suggestions are welcomed.
