I have a 2007 2wd f150 4.6 with a open 3.55 rear. Ive got custom gryphon tunes, CAI, and true dual exhaust. Im running 32.1" now and it hauls *** and gets 19mpg if I baby it. Im putting a 2.5" level and an add a leaf from Autospring on it soon. I would like to know if I could run 285/75r18 with a 3.55? I don't tow anything over 1500 lbs.

Gonna be a tight fit with some rubbing more than likely. I would upgrade your gears as well. That's pretty much a 35in tire

I'm taking a stab and saying Goodyear Wrangler MTR's? That tires is 34.8 inches tall..... You are going to want some gear in the rear. 4.10 minimum
4.56 is the prefered gear

I just put on 33's with my 3.55 and it definitely makes the truck slower, but I'm okay with that since it looks so good. It's not horrible. Maybe if I get energetic and more willing to drop the money, I'll do a 4.10. If money were no object, I'd do it tomorrow. Thanks for posting up the chart, that's really helpful.

For 33's i'd go with 4.10's.......... I ran 4.56's in my 4x4 for a while with 33's...... Really wasn't bad rpm wise.... But a lot of fun tho.
