Thanks to all who replied.
The wheels in question are 18 X 6 formed aluminum, two halves that bolt
together with 15 fasteners. I have tubes but I really don't like the fact
that the tubes weigh almost as much as the tires (MT 26.5 x 18).
There is no O-ring groove and cutting one would seriously weaken the
wheels, they are hydroformed out of Aluminum sheet. I have designed and
fabricated O-ring installations in the past but that experience doesn't
I have seen go-cart two piece wheels that seal with an O-ring
sitting in the v grove formed by the junction of the two wheel halves. This
dosen't seem right engineering wise but it seems to work.
I know there must be some flex as the tire contact patch migrates
around the wheel and wonder if silicone applied at the joint after assembly
will come unstuck.
A problem with applying a sealer between the halves is getting an even
coat, assembly before drying and sealant squeeze out leaving leak paths (I
Any other comments would be appreciated.
