    16.5\" wheels w/out Beadlocks

    Anyone run or know someone that runs 16.5" wheels without beadlocks for crawling?
    I know I have seen this on a few broncos but just want some input.

    Those guys might be running an internal beadlock system...

    Ya, without the safety bead, I cant see them working too well.. You couldn't lower your pressure much or the tire would be cnstantly popping off the rim. My one friend was running 16.5's on his truck for a while in the mud. He popped a bead many times just runnig some ruts with normal pressure.

    Moose,

    16.5" offers a LOT of tire size options that you don't get with 16". I will need the clearance for front D60 brake calipers (I don't want to grind the calipers) so I was asking the same question about "blowing a bead" all the time with the 16.5"....

    There is a company called "Tire-Loc" that sells an internal beadlock.....sort of a custom innertube that holds the bead against the wheel. You have a second valve stem installed so that you can pump up the "beadlock" seperately from the tire. The best part is they are D.O.T. approved so you can legally drive them on the street, unlike every other kind of beadlock I've seen.....The only downside is that they're pricey ($200 per wheel)....but I think when you start pricing other beadlock systems, you'll see it's probably not that much more money after all.

    Damn Mike, only one friend? [​IMG]

    You can crawl all day long with 16.5" rims, just don't try and air em down. Maybe you could add the safety bead if you were fancy enough, but all in all, I think it's more work than it's worth

    Re: 16.5\" wheels w/out Beadlocks

    i am no crawler but i ran them for years with 38.5/16/16.5 swampers
    never had a problem with pressures as low as 10-30psi
    hell I drove them with 0 psi on the street several times when a nail puntured them, you can hardle tell the difference.
    I think that tire is an exception as the recommended rim size that I ran is 9.75x16.5, and the tire is rated as 16" wide.
    a friend with 15" rims was always losing the bead in mudholes

    Re: 16.5\" wheels w/out Beadlocks

    I've ran trails with a couple of guys with 16.5" rims.

    One guy had a Bronco with Dana 60's front and rear, 16.5x9.75 rims on 38x14.50 Swamper SX's. He said he had lot's of troubles with losing the beads when airing down anywhere below street pressure, so he had welded on round stock along the inner and outer portions of the bead seat in order make his own safety beads and hadn't had any problems since. I'm not sure what pressure he was running but you could see a very noticable bulge in the tires, which is very low considering how stiff the SX's are.

    The other guy is running a fullsize chassis with an S-10 Blazer body on it. He had 42x15 Swampers on 16.5x12 rims but had lost the bead a few times on the trail even at street pressure (he would never air down because of this). He finally just switched to some 16x10's with 13/38-16 Swampers.

    Re: 16.5\" wheels w/out Beadlocks

    I am going to try it. I just piced up 3 15/39.5-16.5 swamper 10plys for 400.00 with 80 tread and got a deal on 4 16.5x9.75 steel black mods for 200.00. What the hell just won't be able to air down
