Schwalbe issues warning about Ultremo R tyres

Manufacturing error causes bulge

Schwalbe is has issued a warning about its Ultremo R road racing tyre due to a manufacturing error, which causes bulging in a limited number of tyres.

Free replacements will be supplied, according to the manufacturer. There has been no worldwide recall, however, nor have the batch numbers of the affected tyres been published.

In the limited number of tyres, the casing layer was not sufficiently rubberized and will show a clearly visible bulge, due to the carcass layers separating. This carcass separation will show generally after only a short time in use.

Schwalbe recommends immediate replacement; not doing so may lead to a catastrophic failure, as the casing layer can chafe and consequently cause the inner tube to burst.

"If you notice the phenomenon while riding, under no circumstances should you continue to ride the tyres at high speeds," the company explained. "It is suggested that the air pressure be reduced to the minimum recommended psi while riding at a low speed and with great care.

"If you have been affected by the Ultremo R error we apologize for any inconvenience caused."

To receive replacement tyres, send a photo of the Ultremo R showing the defective bulge as well as a photo of the production code (found on the inside of the tyre) to ultremo@schwalbe.com. A replacement will be dispatched immediately, based on available inventory.
