TBH, neither do I.

Having recently tried some PS4 from Michelin, they are definitely better.

However, everyones application may be different, the driving environment, road temps, tyre temps

But if it's for a road car, wet etc etc....track orientated tyres pretty much make zero sense. As all of them need a few laps to get some heat into them to work. Which is not real life on a road car, on roads.
