Noticed yesterday after a ride that one of my 1.5 year old Schwalbe Ultremo tyres is bulging a bit on the tarmac side, not the sidewalls. Haven't opened up to investigate yet. Any thoughts?? New tube needed/new tyre? Ta.
Hmm - I would be very reluctant to ride 100psi plus at 30-odd mph on anything other than a tyre that looks perfect! You could take it off, inspect for anything obvious and re-fit it. If it still look weird I think it needs to go in the bin.
I had the same problem. Schwalbe have a defective tyre recall notification on their website. Evidently you should, on no account, use the tyre.
Still waiting for my replacement/s from Schwalbe
Schwalbe recently issued a recall for Ultremo R tyres...
"Schwalbe is issuing a notice on some of its Ultremo R tires due to bulging. Due to a mistake in the manufacturing process, the affected tires' carcass layer haven't been sufficiently rubberized.
In some of the tires 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 tires that exhibit this phenomenon continue to be used. The tires need to be replaced immediately. 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 this bulge while riding, under no circumstance should you 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.
Schwalbe offers a straightforward replacement service: send a photo of the Ultremo R showing the defect phenomenon as well as a photo of the production code that is to be found on the inside of the tire to this special e-mail address: ultremo@schwalbe.com. A replacement will be dispatched immediately."

That's for the Ultremo R and fairly recent ones at that.
Bin it.
New tyre.
That could've been interesting. Thanks for the tips.
Should have asked, what's the best online shop to buy a replacement?? Parker International? Ribble? Thanks.
