T1-S is a narrow tire. Tread Rating of 280/AA/A i think. which is pretty good for a 19series tire. Some ppl think their loud, but from my experience, they are ok. Grip is mediocre compared to SO3s or continentals. Its a tire you want to use if ur trying to get away from fender rolling.
I've run every tire you can think of on several cars both street and track. While SO3s are my favorite I like the TS1. Grip is much better than a Yoko AVS for example. The Contis are a little hard. Pilot is great in wet, average in dry.
