Am using a set of this Toyo T1-R. Got it for RM230/piece for 195/50/R15 (price as of 2005 Nov) comparing to Yoko AD07 for RM235/piece...xtra RM5 each. Both made in Japan.
Erm...my opinion on this tyre is overall good. But as for grip wise, I still prefer SP9000 Dunlop, no matter in dry or wet. Previously using the SP9000 but they wear off very fast. About T1-R tyre wear, i'm not sure yet since I've just changed it.
Anyhow, good recommendation. At least another choice. But this tyre is very rare and some place, you need to place order to get the size you want.
