Fix a Leaking Beadlock
This tip comes to us from Circle Racing Wheels:
We all know the importance of air pressure on dirt and asphalt--1 lb can make or break the handle on the car. With this in mind we have come up with a solution for guys that may experience leaking beadlock wheels. Beadlock wheels are the most common wheels to leak since one bead seat is determined by an inner and outer ring portion to hold the tire bead on the wheel: thus not using air pressure to hold the tire bead against the bead seat like on a non beadlock wheel. Also, the beadlock has a welded on inner ring portion that adds to the inconsistency of each part; since not all welds are exactly the same. So the question is: if you receive a new or used beadlock wheel that has a major or small leak, how do you fix the issue?
Look over the weld area where the inner beadlock is welded to the actual rim. If you notice any pin holes or gaps in the weld then you have probably found the issue. Here is how you fix either a pin hole or gap--1. You can run a bead of clear silicon over the entire weld around the wheel. After putting the silicone on, take your finger and run it around the silicone while applying a smaill amount of pressure to help push the silicone into those pin hole areas. Once that is done, you can then clean up any extra silicone that may have pushed away from the weld (do not wipe any silicone on the weld). Let the silcon dry and then mount your tire and you should be good to go.
If there is a gap in the weld where it had not finished its complete revolution, you will need to tack it or weld the gap. Once you are done welding or tacking the area, we suggest that you put a small amount of silicone over the area tacked or welded just to be sure the issue has been resolved.
The last step in trying to resolve a leaking beadlock wheel is to call and ask the manufacturer for the suggested torque on the beadlock bolts. When putting on the outer beadlock ring make sure that the tire is as close to center as possible. Then lightly tighten one bolt down, then tighten the bolt directly across from it. From there, tighten every other bolt skipping over one until you have gotten back to the original bolt you started with. Once this is complete, tighten down all remaining bolts. After all the bolts are tight, torque each bolt to the desired torque suggested by the wheel manufacturer.
If you follow these steps, this should help resolve any leaking issues you may have on beadlock wheels. Hope this helps and good luck to all of you on the remaining season. Dont forget to actually take off the outer ring portion held on by bolts before mounting your tire.
