i had T1-Rs on my car when i bought it 2nd hand from a main dealer. i thought they were good, but swapped to Falken FK452s which i felt were equal in terms of performance. then i swapped to Continental Sport Contact 3s and now i'd stay away from both T1-Rs and Falkens. i went for the because a forum member had purchased them by mistake and was shifting them on cheap. they are a much better tyre,
on the forum the popular debate seems to go between Michelin PS3s and Goodyear Eagle F2s
