[Land-speed] Sealing two piece wheels

[Rick Byrnes]

OK
We move on to crutches.  The go cart wheel with O ring sealing in a 45degree 
groove with no squeeze other than tire internal air pressure can work with a 
little help from Hylomar.  It does not harden and when spread in very small 
amounts it works well.  I have used it on intake gaskets with boosted motors 
at 100" Hg Abs  manifold pressure.  While not tire pressures, the M/T at 
100PSI should help push the O ring into the groove.  I agree with you that 
it is not perfect engineering but probably what I would try next.  The 
surface finish at the O ring contact points is important and the Hylomar may 
help that.

I'm glad we are having this discussion because I have M/T for 16" wheels and 
have not yet decided what the wheels will look like.  I'll run the GY LSR 
tire till speeds require better tires, then switch.
(Should I be so blessed).
