31 inch
33" tire is what we recomend
The maximum tire size for the 2010 Jeep Wrangler Unlimited with the 3 inch lift kit is about 33 inches in height. Tires that are taller than this are not recommended for the Jeep Wrangler.
2" lift kit depending on your tire
A few variables come into play (wheel width, wheel offset, tire width), but the general rule for the Wrangler YJ is... 0 inch lift will fit 30-inch tires 1 inch of lift to fit 31-inch tires 2 inches of lift to fit 32-inch tires 3 inches of lift to fit 33-inch tires
you can put as big as you whant you just might have to put a lift kit and or widening kit to fit a big tire.

7 inch lift kit
You don't need a lift kit to put 20 inch rims on any pickup if the tire profile is changed so that the tire is as tall as stock. If the tires is to be substantially taller (35") a 3" lift will do for 2004-2014 model years.
The largest tire size that can fit on a 2006 Ford F2 50 crew cab, without needing a list, is a 275 R 95 22. Any tire larger than this will need a lift kit.
It depends if you want a bolt on kit or a custom kit, the largest bolt on kit is a 24" Full Throttle supension kit for a 99-04 F-250, F-350, and Excursion, you can fit any size tire underneath it. then you have the custom lift kits, the largest recorded on a street legal truck is a 52" lift with 54" boggers. I personally own an Excursion with the 24" lift kit, and I own an 01 dodge 1500 with 14" suspension lift with a custom 4 inch body, sitting on 49 iroks.
Not without a lift kit. It will damage the tire and frame everytime you hit a bump.
