    Buying wheels and tires next week. Tires will be 37x12.5 16. Heres the question- should I use an 8" or 10" wheel? I think a 10, but a buddy thinks an 8" wheel is the way to go. Some opinions would be appreciated. Thanks

    It'd feel more stable on the street with 10"

    I personally would run the 8 inch rims. Check with the tire manufacturer and see what size they recommend. If you do use the 10 inch rims be prepared to do some fender trimming.

    Interco says basically 8-12" wheel. 12" is way to wide. I will be trimming for fit anyway, so thats no big deal. basically it comes down to preference.

    With a range of 8" to 12" middle of the road would be 10" but I still think that a 12.50 tire looks better on an 8" rim. Like you said, personal preference on this one.

    I think 8" would be a bit narrow. I was wondering the same thing and ended up going w/ 15x10 because I will never go to a smaller tire (I have 36x12.5's right now) and any of the larger tires would be wider. Also my tires are actually 13.5" wide so it isn't too bad with width now.

    If you rock crawl? If so you might want the extra protection of 8". If not then go 10".

    I'd go 10" wide.

    Well a 10" rim will give you a little more flotation and a 8" rim will be protected by the tire sidewall a little more in the rocks. It Depends on what your main use of the truck is. At least that's the "old school" way of looking at it.

    An 8" rim will hold it on the bead longer than a 10" will too...more contact pressure. That said, I just sold my 8's for a set of tires already on 10's and I'm really hoping they hold up to 10 psi.

    I love rocks! Thats what I am tring to gear the rig for. Trails and fire roads are also cool. Don't like the mud to much, so I won't be setting up for that.

    I would go with a 10" rim. I've got a set of 33's on 10 wides, and 35's on 8 wides. The look of the 10 inch wide wheel is a lot better. I don't really air down much past 15 anyway, so the bead seating isn't really an issue for me. Floatation will be better with the 10 inch rim too.

    I think the hot ticket would be a 9" rim...but that would have to be custom made /forums/images/icons/frown.gif
    The other option is a 8" bead-lock...a bead-lock makes the rim about 1" wider.

    I just received new 10" Rock Crawlers via the UPS truck. They are WIDE! My back spacing is 3.75". Any more (to bring in the wheels) would have rubbed the steering.

    Be prepared to stick out a little. Especially on the front. I'm looking for some wide fender flares (see my fender flare post) now.

    If you get 8" Black Rock Crawlers and hate them, I may consider trading. Mine are still in the box. I'm going to get them mounted on some 35's and I'll let you know how it works out.

    If you're going rock crawling run the 8" rims. As stated earlier it keeps the bead better and protects tires sidewall and the rim./forums/images/icons/smile.gif

    When I got my 15x10's I was thinking the same thing. They looked WIDE LOL
    But after the tires were mounted on them they looked way better than they did on the 8" wheels.
    And I did notice that the rig was more stable on the road.
    Especialy when on the freeway doing 70mph.
    My wheels do have some rock rash but it's not bad.
    15 psi has worked for me I have not popped a bead yet.

    If you drive much on the street and a stable feeling is desired then a 10 would offer better control. The thinner the wheel inside of a wider tire the more in and out play, thus the "floating" feeling.

    I said in and out play- hehehe!
