Out on a ride today, I was aware of an unusual sound which presented itself on every revolution of the rear wheel. On closer inspection, I noticed a stick on the tyre that was hitting the mudguard. Thinking it was stuck on with the mud on the tyre, I stupidly pulled at it and the next thing I knew, pssssssst. Bugger, it had actually gone through the Schwalbe Marathon tyre and punctured the inner tube too. Luckily, the escaping air stopped after about 5 seconds and the tyre was sealed for the journey home at least I've thoroughly checked the tyre and I think the foreign object has been totally removed. The tyre has been pumped back up to my regular pressure and I will check it in the morning to see if it has leaked at all. If it hasn't leaked any more air, is it ok to just to leave it as it is, or would it be best to replace the inner tube? Anyone's experience of carrying on using a punctured self sealing inner tube, will be much appreciated.
