Last Saturday I was lucky enough to have some shout me two new Pirellis for my VTR. Very generous and very much appreciated. I spent the week running them in and finding a new lease of life - I'd never realised how much tyres can influence the quality of a ride. So this Saturday it was time to put some serious miles on them. However, the ride was cut short. By a stick. With pretty amazing penetrative powers. My 7 day old rear tyre is now merely a curiosity piece.
