No, I wouldn't ride on that tyre!
Which is particularly relevant because I discovered today that the rear tyre on my Basso also looks like that! (The tyre went flat not far from home so I thought I would try pumping it up land imping home on it, but the valve core suddenly blew out.
Thank goodness that didn't happen on the 40 mph descent that I had just done!)
I have new tyres on order (Lithion 2s are currently going for only £11.99 at Planet X!
) but I will pinch one off my Cannondale for tomorrow's ride. I'll put a new tyre on the 'Dale when my order arrives.)
