From Schwalbe:
“WARNING: Schwalbe Ultremo R tyres that exhibit bulging should be removed from use immediately. Free of charge replacements will be supplied.
ÂÂ
Regrettably some ULTREMO R racing cycle tyres have been supplied into the market that may suffer failure during use due to a mistake in the manufacturing process, as the effected tyres’ carcass layer have not been sufficiently rubberised. In the few tyres concerned, after only a short time in use, the fault becomes clearly visible shown by a bulge due to the carcass layers becoming disconnected.
In no case should Ultremo R tyres that exhibit this phenomenon continue to be used. Replace the tyres immediately!”
