My 275/55R20 Pirelli AT+ are now fitted. The BFG KO2 had worn enough to warrant their removal as they had been very noisy for a long time but 2 are retained as very good spares and a 3rd usable in an emergency. The other 2 besides being more worn on the inside edges have a large split/hole in the outer layer near the inside edge of the tread. The emergency spare has a couple of small radial cracks in the same area suggesting that the large holes may not be specific stone damage, perhaps starting as cracks. The tyres are quite hard - perhaps too hard for tyres only 3.5 years old and travelled 75K kms between 5 tyres so roughly 60K kms each.
It will be interesting to see how the Pirellis perform and survive. Their sidewalls bulge a little more than the BFG but barely any more at the bottom. They look tame compared with the BFGs but that's OK as the RR looks a little more civilised now.
