Michelin Pilot Exalto -- stone-chip trap - Roger Jones
I found low pressure in one of my Golf's tyres today, took the wheel off and found a nail in the centre of the tread. I also found no less than 95 stone chips embedded in the tread. The Exalto tread seems to have been designed as a trap for stone chips. Watch out if sharp stone chips are a hazard in your neck of the woods.
