    im upgrading to either 3/4 or 1 ton setup and im not sure what rims to get. i will be getting new 35s so changing rim size is an option. should i get 16 or 16.5? or stay 15 and grind calipers if i get a dana 60? also what width rim should i get? im gonna get 35x12.50 bfg at.

    15's are better to air down, more lip on the rim

    I only run 16.5's B/C i use US hummer beadlocks.

    Both 15 and 16.5 have good tire selections.....

    16 is quite limited. Check out a typical 4WPW ad sometime, and you'll see what I mean.

    15" = caliper grinding or crazy backspacing
    16" = poor tire choices
    16.5" = no safety bead

    Each one has at least one drawback (and workaround)....I'd spend some time looking at the 17" stuff now too, it's going to get more and more prevalent (from what I can tell) so if the tire sizes make sense for what you're doing, it could be yet another way to go.

    safety bead keeps the tire from slipping off the bead area of the rim at low pressures..16.5s suck..you let all the air out and the tire pops off the rim..you can get most tire sizes in 16...

    i bought new 16.5's lol. thats what i like. I like aluminum wheels and one day would like a D60. Cant have aluminum 15's on a 60. 16's dont have all the tire sizes. My opinion, if you run rocks, or where you will need to run 5psi, and dont my steel wheels, get 15's. Get 16's if you want a bit bigger wheel, possible aluminum wheels over a D60(im not sure), but dont mind the limited tire selection, and need the air downability(whew i need help lol). Get 16.5's if you are like me, like aluminum wheels, dont need to go below 12psi, and want less sidewall flex, and still have a good tire selection. 16.5's fit my needs. But others swear by the 15's and swear at the 16.5's.

    Poor tire choices in 16"? Try getting a Goodyear MTR in a 16.5....

    I have seen a lot of the newer designs aren't made in 16.5" as I have a set of them for future use. Many of the tires I would like to try aren't offered in this size.

    Pro Comp X-Terrain
    GY MTR
    Trxxux MT
    etc.

    Just my thoughts....

    I just got a set of the Super Swamper IROKs in a 39.5 x 13.5 x 16 on a set of 16x10 black crawlers. Excelent tire, perfect size and safety bead to boot. I was not too thrilled about grinding to fit my old 15's, so I shopped for quite a while untill I settled on the IROKs.

    i dont run below 20 psi now so i dont plan to go in the teens if i do go with a 16.5, so i shouldnt have a problem with popping the bead. if i run a 12.50 tire, should i go with an 8 inch rim? or a 9.75-10.0? what backspacing are you all running? i want my rims tucked in as much as possible and want to get some ideas, thanks

    I say buy the 15'a with no more than 3 1/2" backspacing. Tires for 15s are cheaper, there is a good safety bead and you won't notice the difference between the sidewall on a 15 and 16.5. Also, 15" rims are cheaper.

    Rim selection for 15" 8 lug wheels kinda sucks. That's what I'm looking at myself right now. I bought 15's for tires, but haven't been overly thrilled with the choices of wheels avalible in a 8 lug flavor. Probley just get the old trusty white wagon wheels.

    That's what I got. Hit them with Krylon flat black and they're good to go. I used to have chrome but I prefer black for my truck now.

    why only 3 1/2? doesnt that make them stick out too far?

    The more backspacing you have the more grinding you will need to do. 3 1/2" doesn't stick out much. Decide what tire you want to run (brand/size) then pick you rim size. Otherwise you may end up w/ rims that won't fit the tire you want.

    My choice for rims would be 16's. There are getting to be lots of tire choices for the 16" rim, until you get to around the 38-39" range or bigger and then they drop off. But I expect to see more sizes keep coming out. 16.5 rim tire sizes are really starting to drop off, I think BFG only makes maybe 3 sizes for the 16.5's but has probably a dozen sizes for 16's.

    well im not going any bigger than 35, its my DD and i think 35 is too big. why are 16's so much more per tire? does anyone think they will go down ever? quite a bit more than 15.
