Anti-Coning Rings for Beadlocks with Pitbull Rocker Radial Tires

Hey All,

In a pinch and need some advice. I am in the process of buying a diy weld-on beadlock kit for my 15" steel wheels. I really want to add anti-coning rings to prevent the outside ring from warping. The problem is that I plan to run a set of 37x12.5R15 Pitbull Rocker Radials and the bead thickness is close an inch thick. I contacted the manufacturer and they confirmed it is about an inch thick and from online research I found that people have measured it to be around 0.94".

The company that I am buying the beadlock kit sells anti-coning rings for the wheels that is basically 3/16" thick x 1/2" wide flat stock bent to the circumference of the inner circle for the inner ring. I am pretty sure that an anti-coning ring that stands off of the inner ring a 1/2" will not help me here since my bead thickness is about an inch thick.

So my question is how high should the anti-coning rings stand off of the inner ring? should it be equal to the bead thickness? Should it be about 75% to make up for the rubber compressing?

I think I am going to add my own after I get my wheels by buying 3/16" thick flat stock that is at the right width for my tires but don't know what the right width should be for a tire that has a bead thickness of an inch.

Thanks in advance to you guys for helping me out.

You would want the tire beads to be able to "crush" a little bit in order to seal.

Instead of steel, I've got a buddy who just ordered a strip of UHMW plastic (like 1"x1" square x 60" long per rim). The plastic is relatively hard but is still flexible enough to bend it into an "O" shape. Since it's sort of "spring loaded" when rolled, it springs open against the beadlock bolts.. holding itself in place.

The stuff can also be cut/sanded/ground down to a whatever thickness you need.

I would probably mock up one of the tires, lightly snug the outer ring in place, measure the gap between inner/outer rings, and then pick the thickness that's the same (or slightly less than) as that. If you've got access to a table saw, planer, bandsaw..etc, it would be really easy to trim down the strips to allow a good clamping of the bead without coning the outer ring in.

Or use a V-belts that fit the outside the bolt hole's, there probally the cheapest thing to get. If you need thicker than the normall parts store offers try a truck stop.
Like BESRK mock up a tire first, I know my 39's had a thick chunk on the lip also, probally around 3/4-7/8" thick and I have no issue's.

Heck I don't even take my own advise, I dont run any coning rings. Had the tire's on a weld on bead lock for years with zero problems.
I bet my rings are bent but I really dont care they lock that outer bead in tight and thats all that matters, oh I also run 32 grade 8 bolts per rim.

i'm not running a coning ring with my pitbulls. I also didnt grind the weld down on the lip of the wheel. few friends have started to leave the weld "hump" and it seems to seal better.

Thanks for the info guys. I've decided to wait untill I get the new tires to then figure out what to do with the an anti-coning ring.

Since 3/16" flat stock is so darn cheap I might just go that route. 5 pieces of 3/16" thick, 3/4" wide, 48" long flat steel is only about $25.... hopefully 3/4" will work well with the .93" width tire bead. I'll keep you guys posted with how well it goes.

If anyone else is running Pitbulls - how well are they sealing and what trick (if any) have you needed to do to get them to seal well? I have heard that since the tire bead is so wide that it doesn't seal well in the bead seat on a normal wheel where the seat is only 3/4" wide... thoughts? Anybody do the duct take trick by making a layer of duct tape to act as a new lip for the tire to seal up to?
