I've just jumped across to the Toyo Proxes T1-R on my Audi after using Continental Sport Contact 3's.

I rate the T1-R quite highly, dry weather grip so far seems good and the wet weather grip is quite acceptable as well although not as good as the Continentals they replaced. Will have to see what they are like on wear as they'e only been on a week but I only got 15mnths out of the last full set
