i've driven T1R's on track 3 laps and they were very greasy, the side walls gave terrible tyre roll and didn't inspire confidence.
reo40's great dry tyre superb for dry track days and to be honest not as bad as people make out for road use. they are still very predictable. reo50s much better though.
if i was looking around the T1R price range i'd go straight to the vredesteins, and thats what i did. great tyre for the money. miles better than the toyos.
