Huh?
If you use your oem 20 inch wheels you can easily fit 305/55-20's (33x12.50).

If you will consider just adding a leveling kit then you should be able to run 33 x 12.50. Also the tire itself does matter as some sidewall designs can cause issues. Any clue what tire you want to run?

This is very true. but i know there are at least a million posts on this topic

stick with a 33 or less. stock 4x4 usually come with a 32.5" or so tire to begin with. watch your backspacing if you arent going to lift the front., which you can also find what people are using, just hang out in the wheel tire section long enough. Thats what i did and it worked great. wandall knows his stuff too!

20x8.5- +10mm and +35mm offset
20x10- -24mm offset
20x12- -44mm offset
This looks like your options as far as the 20s go in the rockstar. Id say if you do the 20x10 I would want a leveling kit at least if i were going to run 33's... I think the 8.5" wheel some guys on here arent having any problems with, unless you plan on lifting it later on i would probably go that route.

Then what are you looking for?

I saw dozens of pics of Rock Stars on here when I was searching for wheels and I wasn't even looking for RS's.

If I'm not mistaken, those have a pretty good negative offset which is really going to limit your tire size without rubbing.

I was going to run the 20x10 with a 35 inch MT

Im gonna I wouldnt do it without a 6" lift. Theres a few guys on here saying it can be done and apparantly they are doing it, but with a 10" wheel with that offset you are gong to have some issues especially if you arent going to run at least a leveling kit. 33 is the largest i would go with that wheel and you will still be trimming a little plastic. The tan truck in my gallery has 33's with a 9" wheel with 4.5" of Backspacing and i rubbed the plastic on the front and cleared the part by the rear fender by like a half inch or so.

im not sure why i wrote "Im gonna", but anyway......im just saying for me I wont do a setup like that without it.. And you need a leveling kit at least. its possible, but you may need to do some trimming like the post above i sent you.
