Usually after grinding tyre sidewalls down to get overall width to 10mm you end up grinding the glued join between the wheel and rubber...is it OK to run a bead of superglue round this join without it being measured as part of the tyre as it's not part of the tyre?  I'd rather reinforce that join than chance a tyre coming loose half way through the proxy.

Yes I will be measuring the rubber part of the tyre wall, so that should not be an issue.
