Hello everyone, I am resurrecting this thread as my fairly new Schwalbe Marathon Plus rear tyre suffered a catastrophic failure when going to work recently.
Luckily it was nearly all the way into work so I only had to push my bike a short way to get there.
I was passing a building sight when I heard an almost explosive bang and shortly after realised I had a flat rear tyre.
I took a photo of the nail which went through the sidewall twice with my mobile phone so it is not the best quality but shows that even "puncture proof" tyres sometimes have no chance to prevent a blow out!
Later that night after I finished work at 11pm I had my Bearprint Ebike in the work front reception area with the rear wheel out changing the innertube before I could cycle the 12 miles to get home.
The Security guy was very understanding about it waiting for me to finish the job.
The punctured innertube had a split of about half an inch in it where it blew out with the high pressure I had put in it just the day before, there was no way it was patchable. My experiences in the past of patching tyres is that after a few days the patch always fails.
Today I tried to repair the 0.25" split in the side wall where the nail exited using superglue.
This seems to have worked and the innertube no longer bulges out of the split!
I still have great faith and belief in the Schwalbe MP tyres as this puncture was very unlucky.
Barry.
