Not Ranked
I run 275/40/17 and 315/35/17 and the following tires.
Goodyear GS-D3, the best so far, good on the track, great on the street and in the rain.
Sumitomo HTRZ, a great tire for the money but nowhere close to the GS-D3s
Currently running Vredestein Ultrac Sessanta. An excellent tire but not quite as good as the GS-D3s.
I'd like to try the new Kumho Ecsta XS. These are available in 275/40/17 and both 315 & 335/35/17. The rain performance isn't quite up to the GS-D3s and is real important to me.
