    what is the stock width on an '89 rim
    it says 7 / 8 on the inside of the door pannel
    i'm looking to buy 35 x 12.5 x 15 mt claw radials and was going to buy 15 x 10 rims until i read that it looks too flat on sidewall
    can i fit this size tire on the stock rims (if they are indead 8")
    any suggestions??? :confused:

    Yes you can put a 12.5 in wide tire on a 8 in rim.

    If you have the steel wheels, they are 8" wide. If you have the factory aluminums, they are 7" wide.

    Either way the 12.5" tires will fit on both IMO.

    I have all my 12.5" stuff on 8" wide wheels

    although again, a search would have netted lots more info too...

    Like mentioned, you can run the stock rims. Personally I would buy some 15x10's because they would look much better and also give the truck a few points in the looks department with some new, not stock rims.

    i have used both 8 and 10 rims for 35s... personally, I hardly noticed any difference in performance or appearance. I dunno, maybe I just don't care. In any case, go with whatever is cheaper for you. Either will work fine.

    depends on the weight of the rig, type of tire etc. There is no single answer to that question. In my procomp MTs on my K5 I generally run 30 psi (35 psi is max recommended pressure).

    I run 15x8" rims with 35x12.5's. I run at 28 PSI on the street. I like the 8" rim because of its better bead retention and the rim is less exposed to rocks when I am out rockcrawling.

    That must be personal preference because I don't like the way 10" wheels look at all. I would stick to a 7, 7.5 or at most 8 inch wheel at most. FYI no one races on 10" wheels in the desert. Not even with the new 39 x 13.50 BFG Project tires. Looks is a personal thing, I guess.

    Is there a reason why you chose to pick at my opinion that was meant for the original poster? :confused: I don't think the original poster has desert racing in mind anyway. :rolleyes:

    Obviously by your post and user name, you like Desert racing. I don't know what they use for widths and never really cared, not my cup of tea. Regardless, it's completely not relavent to this thread anyway.

    I run 14's, they look cool and I don't ever have to air down because of the flat foot print they provide. I think a wide tire sucked in on to a skinny rim looks dumb. Sorry you don't like my taste. Have a nice day.

    I'd never want to get in a squabble over bling with ya rf, but a wide footprint is only half the benefit of airing down... an aired down tire has superior comformability that a "properly" inflated tire won't have. :)

    I would definantly agree, but seeing how my K5 is pretty much only a mud truck, I doubt there is much for the tire to conform to. Or, at least it's not as important in the mud than say something like rocks.

    IMO, the 15x10s look better, but if you're worried about the bead take someone elses advice.

    Personally I think(have) a 10" rim for 12.5x15 bfg a/t's, look the best. However they will work on a 7" stock aluminum rim. they just don't get the girth on a smaller rim.You want big tires to look big. that doesn't happen with a narrow rim. they just look taller..

    i've got 35x12.5x15 BFG a/t's on 15x8 rims. they are pretty sucked in. wasnt quite as bad when i had 33's.the outer two inches of tread doesnt make contact with the pavement, i even tried decreasing pressure to 28psi, didnt help.i can also feel the tires rollover in turns. i think 10" rims would help that.

    if your tire is naturally crowned more i dont think it makes much difference. ive seen 13.50 tires on 7-8" rims that looked good. on my truck i want the max amount of tread life and stability. i think i'll be switching to 10" rims pretty soon.

    BTW pretty much every truck i see at the local mud pit airs their tires down to single digits. i think if you have that bulge at the bottom of your tire you've effectively increased your footprint, and that will help traction whether climbing a rock or swimming thru a mudpit.

    here's a pic of my truck w/ 35's on 8"s. you can see how crowned the tread is. these tires should be almsot completly flat on the tread.BTW, sorry they are huge, my photo editor isnt working

    Most guys air down. I never do because I wheel mostly on our ranches so I hit a wet spot by a leaky irrigation valve, pipe, ditch, etc... unlock the hubs and back to work.
