Quick Questions
Admiral Ackbar:
I've had sidewall problems with conti tires before, grand prix something-or-anothers, haterskins, ultra sports. all sidewall blowouts or weird deformed casings after a few hundred miles, never noticed threads like that coming off though. but i have had it happen on other tires, no failures in those cases though
Narcoleptic Insomniac:
I just smoked a joint for the first time in months so bear with me if these doesn't make any sense.
I remember reading somewhere that the pressure equivalent of typical tarmac road surface on a hot day is about 95psi. If that is true, wouldn't it mean that running 100+psi in your tires actually increases rolling resistance from the road deforming more than the tires?
Brooklynrider:
I've read several articles saying that 23mm tires are in fact slower than 25mm tires because the 25mm tire absorbs the shocks of the road better. Same applies to psi.
Kinchy:
I've been running 90 psi in 25c tires for a while now and much prefer it to harder pressures, especially due to the current state of the roads.
Also, my Schwalbe Duranos are doing exactly the same thing Tom

They're Conti GP4000s. Is it a problem meaning they need replacing to avoid some kind of blow out? If so I'll be pissed off, cant have done more than 1000 miles on these!

Personally I wouldn't be too worried about that. The main structural casing threads run sort of helically around the tyre, that looks more like a thread from the sort of "tape" they put over the bead which isnt really structural. Probably a good idea to pump the tyre up 30% above your normal running pressure as a test, but if it survives that OK you should be fine.
Ride it at your own risk though.
