5/5Bridgestone Potenza RE050AAs far as I can tell from my observations, they are doing great. I have not had the opportunity to try them out in the snow, but I would say that their grip in wet weather is impressive.
5/5Nankang Sportnex NS-20The tyres work very well and look great, but the ultra low profile is a pain with speed bumps - or maybe speed bumps aren't tyres friendly!
5/5Nankang Sportnex NS-20So far so good. We are planning a driving holiday to Spain soon, so we will see how they cope with the travel.
4/5Michelin Pilot Sport 4 SThey do perform decently, but there are now other high-performance tyres that either match or exceed the PS4s. I might look into trying those next.
4/5Kumho Ecsta PS71The tyres provide excellent grip which instills me with confidence managing corners and driving in wet conditions - a must in Scotland!
5/5Pirelli P ZeroOutstanding traction and control in any weather, and extraordinary grip on the road.
