Had to get a new tyre today for my BA XR6 due to a cut in the tread that caused the tyre (left rear) to deflate. Apart from the pain of replacing a near-new tyre, I really don't undestand how this happened. The tyre guy reckoned I'd run over something like a kerb, but I certainly don't recall doing this.
The cut/split was about 7-8 cm long and had gone through the belts. It was on about a 45° angle to the tread. Any ideas? - could this possibly be a manufacturing defect? The tyre was a 235/45-17 SP3000A, 8,500 kms, running at 34 psi.
