Slow Leaks

[rob hod]

    I have had similar problems with the ronals on my CGT, but two wheels
have had new tyres fitted which has more or less eliminated the problem, I'm
not recommending that you go as far as new tyres in your case, but in my
case it just so happend that they neeeded replacing, and combined with a
clean up of the seating areas the problem was reduced to a bearable level
(occasionally need a couple of psi adding).

    I would hazard a guess that blasting and powder coating would solve the
problem.

    As far as tubes in tubeless tyres go I've been told more than once
before that its not a great idea. I don't pretend to fully understand the
reasons but its something to do with the fact that tubeless tyres are just
not designed to have a tube in them, for example you can get a situation
where a pressure develops between the tube and the tyre , which causes
porblems, and there are friction issues associated with high speed usage
that could lead to big problems just when you don't want them.

    I'd regard a tube in a tubeless tyre a get you home bodge, or a get you
to a place where you feel happy about having the real issues addressed, not
as a cure to a rim leakage problem.

    Incidentally on some euro cars, (I'm thinking especially 70's Alfa
Romeo) the magnesium alloy wheels will eventually go porous and will never
hold air again - at that point they're junk. Don't think this is a prob with
ronals as I believe they are a more conventional Aluminium alloy.
