This may be wierd but I have a problem with my beadlock wheel not sealing on the tire. I run a DOT tire on a 8" wheel with a beadlock. I tried running a tube but it just pinches the tube. Without the tube, I have tried silicon, gasket sealer, and even foam insulation(I was desperate). Other than making the wheel into a door prop, anybody have any ideas?

I am using a Cooper Cobra tire and as far as I know the beadlock ring is straight. I at least know the wheel is. I have tried clear silicone and black gasket sealer. Know of anything better to try?

Check the welds on the flang, I have purchased several that the welds were cold welded and didn't hold air

Is this a factory bead lock or did someone else put it on? You could have some pin holes in the weld itself.

I had the same problem, and what worked for me was what I would call a "shim". I laid the ring on a piece of 20 ga. sheet metal and traced the outside, then came in I think a 1/2 or 3/4 in. and cut it out. Mounted the tire, then laid the shim on the bead and then bolted on the ring. Worked for me.

I am using a factory style wheel. I will keep the shim idea in mind. I was told to use an implement tube instead of a passenger car type tube because it isnt as large but will still inflate the tire. I am at least going to try it. Thanks for the help.

as already stated, pin-holes in the welded area are not uncommon ..... I know some who have had good luck putting a generous layer of silicone over the weld bead.

I like the tube solution myself. Firestone's Drag Race tubes (30 something from summit) last FOREVER. Standard Radial tubes work reasonably well (as low as 10 psi on a 8" rr).


one important thing to keep in mind is that your bead-lock was not neccesarily prepped for a tube by the manufacturer. The BIGGEST killer of tubes in beadlocks is the sharp edge on the back side of the welded in ring .... this MUST be radiused or your tube will fail. Also look for any weld splatter (or other roughness) by running your hands over every surface the tube may encounter.
