I know I want a 305/50/20 tire but I'm not 100% on the wheel size. The part I'd like to know is how wide of a wheel would I need. The 20x9, 20x10, or 20x10.5? I really don't want a lot of tire sticking out the wheel well and not matching the back and all I plan on doing with the rear is using the 3" drop shackles. Any help/advice would be greatly appreciated.

I would do a 20x10 with as much positive offset as you can find.

Ok, thanks. Not a lot of these places online have selections for the offset. I'm really liking the BMF 8 Lug Novakane Stealth's But man they are kinda spendy.

A 20x9 would work well also with that tire. The 20X10 BMF's below have a 305x50Rx20 toyo on them. They are also at max negative offset which means they will rub with out the Bushwackers and the torsion bars up. Like Josh said just make sure you go positive as much as you can on the offset and they should fit fine even lowered.

Thanks guys. These are the bmf novakaines in stealth black http://www.thoroughbreddiesel.com/BMF/wheels.htm just don want the glossy ones. I don't see where I can choose the offset. If you know where I can get these cheaper or be able to choose the offset please let me know. One reason why I would be ordering through them is free shipping and I may be getting a couple other things in with the order and just have it all shipped at once.

Just got off the phone. They have been doing some tweaking with the site so the price was obviously wrong. Guy told me for the 20x9 (he is gonna get back to me on 20x10) that they come standard with 5" backspace and 0" offset.

So every place I read on the BMF's if I try and do the 20x10's they are saying I will need a lift????? I don't want to have to trim my bumper either. Are they wrong? If I can do the Toyo Tires PROXES S/T 305/50/20 with bmf 20X10' with zero trimming I'd like to do that. Is that going to work?

20x10 are meant to work with trucks with lifts. 20x9 are meant to work with stock or leveled truck. You would have to trim with 20x10 and 305's for sure without a lift and 20x9 you might not have to but I'll bet it rubs at least a little. BMF as far as I know unless it changed has a negative offset with 20x10's and positve with 20x9's those are the 2 options, no choosing offsets except to choose the wheel size and a pre-set offset.

Kat is running 305/50-20's on Wendy, and they fit well, and don't stick out or rub at full lock.

I'll see if I can find the specs.

In any case, backspace is the key. You want at least 5" inches of it. Dodge rims have MORE backspace and the same lug pattern. A lot of "Chevy" rims have 4.5" BS which is OK for 30 years ago, but not today.

thanks everyone, I'm still searching but other than the 20X9's having the standard 5" I cant find anywhere where I can choose differently. then again its sounding like the 20X9 is what I'm gonna need if I don't want to trim or lift. anyone have a site where I can get a decent price on them?

Best I can tell right now they are 9" wide with 5.71" backspacing (+18mm offset). They are Moto Metals MO961. Last 4 digits on P/N are 0218. We had to do a small trim to fender liner, but no body trim.

You can take a look in my garage. I have 20x9 ultra predators. I believe it was +14 offest but it was so long ago since I ordered. I like the stance of em a lot. Tires are 285-55-20's. Next time Im going with 305's
