Went for a ride at the weekend - tyres at full pressure.
Got home - still tyres OK
Left overnight and front tyre flat!
Now I always repair if I can, so this morning, removed the inner, checked the outer and pumped up. Could not find the leak, so into a bowl of water.
This revealed the leakage - it was in the middle of an existing patch that I had stuck on last year.
Removed the patch and sanded down the area, but the old glue refused to come off completely. I did stick a new patch over it and it seemed to hold, but by this time I had lost all my faith in the repair and imagined that out on the road, it would probably fail again.
So into the bin it went.
Felt a bit guilty as otherwise it was a good newish tube, but with winter ahead of us, didn't want to risk it.
