I'm plenty capable on track mate, I'm pretty happy trail braking so I guess I'm hard on tyres as a result but all my tyres suffer the same, those tyres are crap, simple as that. I'm directly comparing the T1Rs to vrededteins, eagle f1s, PS2s, conti 3s and pilot exaltos. All were much better than the T1Rs with no change in driving style or car.
So IMO either the T1Rs are good and the others are awesome, or the T1Rs are crap and the others are good. Its all relative and of course subjective, but I would never buy them again.
