+1 from me for Rainsports, mine are upped from 205s to 215s. Paul Roddison recommended these, and set my four wheel tracking at the same time. Mine had Potenzas on before, the grip was applling in the wet and they seemed very noisy too; in fairness they were also very old. The car is (imo) now superb in the wet, and I don’t see a problem with Rainsports under any conditions really. The size increase also made the speedo more accurate (when compared to Garmin satnav) and gives a bit of wheel rim parking protection too.
Roddisons was also the best price I could find at the time too!
