Apparently they make the rims in 20x8.5 with a +10 or +35 offset but they just dont show it on the Offical site. I found this when searching thru wheel dealers.

this link then in the drop down menu...

I go with dura trac's they're great all around tires. However a 285/60/r20 is just gonna be too big and not clear properly with a 10" wide wheel. You need a tire that's less than 11" wide really with that wide of wheel and small lift, even though to really fill out the wheel properly you should go with a tire about 1.5" to 2" wider than the wheel. So it's reallly up to you at this point: Do you wanna be able to still make as sharp of turns as you can now? Or are you willing to sacrifice that to make the tire's look better on the wheel?

Either way go with the 10" wide wheel at the most and don't go over a 33" tire. Even .4" will make a difference.

Also have you decided on what level your going to go with yet?

EDIT: Definitely get the 8.5" wheel then.

 

Probably just a leveling kit, possible trimming if I just have to

 

I'd recommend a 2" it's the biggest you can go without needed aftermarket upper control arms and it'll give you the best bet for clearance. If your trying to save money go with either the daystar spacer or the springtech spacer (it'll run you somewhere between 40-80 generally). if you want it to ride better I'd go with a set of 2" lift coils.

 

Yeah, thats what i've been looking at is the 2" one

Ok, so i've used some calculators and this is what i've come up with...

285/60/20 is 11.2x33.5 I can fit the 10" or 8.5" wheels but the 10" are almost even with the sidewall

285/55/20 is 11.2x32.4 can fit 10" or 8.5" but thing as above

305/55/20 is 12x33.2 can fit 10" or 8.5" but 10" would look best

275/60/20 is 10.8x33 can only fit 8.5

this is the site I used...stock tires are 275/60/17 which is 10.8x30 not sure about rim width or offset
