BMW Alpina B3 Tires

I had these on a Alpina B3 2014. On the road, they coped quite well. Having big 20" rims is hell for the tire, especially when used in a city full of potholes. They held up remarcably well (used the XL variant), much better than the Pilot Sports I had before, that developed blisters in an instant. But, from here on, there is not much positive. Took the car for a track day, after two 20 minute sessions, the tires were done for it. While at first they where quite ok (actually I was impressed by how progressive they were at the limit), massive chunks have started to rip apart from the tread, rendering them useless.
Very, very dissapointed by a tire that is "performance" oriented.
So, for road use, maybe, as I bought them for half the price of a set of Pilot Sport's. But anything else, NO!

*PLEASE DO NOT FIT THESE TYRES TO THE REAR OF YOUR CAR OR AT ALL IF YOU CAN HELP IT*

Spun out on damp roundabout at 5-10mph.

Below average in the dry and lethal in the wet.

There is a reason these are the cheapest tires in this size.
