Earl, et al:
This is a follow-up regarding tubeless wire wheels, Michelin XAS tires, and
tubes.
I have corresponded with Michelin and Longstone and here are their answers:
Longstone: "Dear Sir, Thank you for your email, The tyres are of tube type
construction,so do require inner tubes. The thing that makes a tyre tubeless
is a coating on the inside of the tyre that seals them and stops them from
being pouros something the 180x15 Michelin XAS does not have. It is clearly
marked on the side of the tyre that they are Tube Type".
That marking was clearly disregarded by the installer of the tires (Len).
Also, I did not have a problem with the porousness causing any loss of air
during the 7,000 miles the tires have been in use.
Michelin: "...Regarding your question about the structure of the tire itself,
this particular tires in the size : 180HR15 requires a tube due to the
construction of the inner liners...".
Although there was no response regarding my questions about a sealing bead or
the safety of running these tires without a tube, on the basis of these
responses, inner tubes were installed in the XAS tires on my BJ8 today.
