Hi guys,

Just wondering if any of you are running 18" wheels with offroad tires? I am looking to get some All Terrains approx. 32" so I wanted to see if anyone has this set up. Plannin on MarkMC lift front/z71 rear.

I would run smaller wheels but this is what my TB came with stock so I'm trying to make do. I really like the H3 wheels GMLee and Chewy have but I don't want to spend all that extra money on new wheels and spacers, unless I can get a great deal like them.

So I figure running the stockers will be my cheapest alternative. Even tho the tires are a bit more. But if I go with 265/65/18 do you think I'll need spacers?

Thanks in advance for any help.

Oh and so you guys know my mission: I want to do this for work, I work in a quarry and have to use my TB because of the car program I'm on so I figure I might as well stuff so bigger tires under there. But I would def like to do some trails with my buddy whos got a jeep, even tho I prob wont be able to do half the **** he does with his 37's. haha. But I do alot of highway/city driving too so thats why I want AT's.

It's not optimum, but I understand your reasons. That size is 31.6" diameter, nominally, but depending on what the manufacturer does, it may be a bit larger or smaller. It's been posted a LOT that 30.5" is the max you should aim for without wheel spacers.

And in general, 265 wide tires in that diameter are specified for 7.5-9.5" wide rims, and our OEM 16 and 17" rims are only 7" wide. I don't know about the 18's, but you should check.

If you're patient you can find a great deal on the wheels. I got my set for $100 from a guy that had them in his shed and just wanted to get rid of them. Hardtrailz400 found a set last week locally he picked up for $100-125. I got my set of wheel adapters from motorsport-tech.com for $280 shipped. So for roughly $400, plus Mark's front kit and Z71 springs, you have a set up that can fit a 285/75/16 (32.8" diameter) tire with minor cutting.

As for your buddy's Jeep, just ask Roadie, good off-road vision and skills can make up for lack of gear. He has been places the Jeeps wouldn't or couldn't go.

thanks guys, i guess ill try to be patient. Chewy, any clue on to how much shipping would be? I suppose I could always sell the stocker to get back some of the money spent too..

I was also maybe thinking about picking up a set off of ebay (h3 wheels) with tires because there are a bunch of sets on there for not too much. But I just don't want a wimpy lookin tire..most of them come with goodyear wrangler or bf goodrich rugged trail..but i guess they would get the job done and then i could always save for new tires.

But anyway heres some pics of my buddies jeep. Trailvoys aren't doin this for sure..haha

Pretty sure all the stock 18" wheels for our vehicles are 18x8. I found a site at one time that listed them; I'll try to dig that up again and link it. :bonk:


Edit: Ahh, here we go.

You say WHAT? 50 degrees slope isn't enough for ya?




ok ok, i stand corrected. that is pretty sweet.:hail: and i know you and some of the other offroad guys have definately put the TV thru the test. I mean I'm not even saying I will be doing half the stuff you are. Just want a decent tire that I can take offroad time to time.
