What is the biggest size tire I can put on my stock 2007 f-150 4x4 with a 4.6 v8? No lift no leveling kit and no programer.

 

What size did it come with? Check the door jam.

 

235/75r17

 

With everything stock 255/70r17. 265/70r17 may rub or will throw the speed odometer off. Also depends on all terrains or all seasons. A/ts usually have deeper tread.

 

Well I have some 17x9 rims and my goal is 33/12.5r17 nitto mud grapplers. So what would I need.

 

31/12.5 are around 265/75. Sooo 33s would be around 285-295/75 at least a lift kit prob 3 inches at least. Also to do it right new ball joints with grease fittings. A lift and big tires will mess up a factory suspension. That's how I would do it. New shocks struts 3-5 inch lift, poly bushings for front and be prepared to do ball joints every 15000 miles.

 

Ok so a leveling kit wouldn't work? And have you heard any good or bad about the edge cs. I found a used one for $375 is that a good price or not?

 

33's...35's with a level

 

Big Country...you're not getting the advice you want. Your setup, (with mud grapplers) WON'T rub with 33's!!! You don't need greased ball joints or lifts or what not. If you're gonna be a bear...be a GRIZZLY!!! Do it...you won't regret it! Visit my garage if you want to see the mud grapplers!

 

Thanks man!!! I didn't think that was right because my dads 2004 f150 2wd has 265/75/17 on it. And is the edge cs any good if not what is the best for power but also let you reprogram you speed-o?
