I am running tubeless wheels, scoot rs painted rims and conti navigator tyres my problem is air leaking from around the valve not a lot but enough that they lose 10lb a week.
The valves are the ones supplied with the rims i found these http://www.demon-tweeks.co.uk/products/ ... =BBTVB1508
and wondered would they work better.
they will not fit tried them myself as i live near tweeks get the bikeit ones from them ive used 6 without problems i take it you have the pull through rubber type fitted you can also put puncture seal in this will do the trick
