Schwalbe has issued a warning over a subset of Ultremo R tires. This is only a warning and does not constitute a recall. If your Ultremo tires start exhibiting bulging Schwalbe will replace the tires promptly at no charge. If your tires are affected you should see this after a short time in use. Most will not be affected. See the PDF (attached at the bottom) for more details.

From Schwalbe:

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!

Danger: Not doing so may lead to a catastrophic failure, as the carcass layer can chafe through consequently causing the inner tube to burst. If you notice the phenomenon while riding, under no circumstances continue at speed. It is suggested that the air pressure is reduced to the minimum recommended while riding at low speed and with great care.
