CMA Wheels - Tubed or tubeless tyres

#1 PostAuthor: Fred the Zed » Tue Nov 08, 2016 11:33 am

Hi

Anyone know if you can fit tubeless tyres to CMA 5 spoke alloys? The wheels do not have any indication cast into them.

I need new boots as the 1980's tyres on the set I bought a while ago are a little worn and hard. Its currently got tubes fitted with tubeless tyres.

I have (had) 2 sets of 3 spoke CMA. Both ran happily with tubeless tyres. No loss of air other than what I would believe to be normal.

Great thanks

I'd prefer tubeless as its less unsprung weight and less likely to instantly deflate with a puncture.

Took the 5 spoke CMAs into Wheelhouse Tyres today for a set of new boots and the CMA rim profile is one that definitely needs tubes.

So new tubes and Avon AM26's for the very odd sizes of 140/70 x 18 and 100/90 x 18.
