I've heard good things about the T1-R from some friends who've tried them. I'm a little surprised that they wear well, as some years ago I went through several sets of Toyo T1-S on a previous car (much less powerful) and they were good tyres but wore quickly. T1-R are the successor to T1-S.
Might give them a try when I've worn through the current tyres (which will take some time at my current rate of using the car). Thanks.
