Pirelli PZero gravel rally tires. Known to be incredibly rugged. See if you can spot the problem area

I suffered a puncture on the other one at some point. As a testament to this tires strength though it survived a sustained ~115mph run with no failure. Wasn't exactly a smooth ride though.... if you have ever seen the police car episode of top gear where clarkson puts those metal spikes in the centers of his wheels and it throws the balance horribly off causing the car to shake like an off-balance washing machine? Yeah not much different from that.
At least my car won the rally.
