I've never managed to trouble my standard Diablos on road or track, as I've said often enough, if they could talk they would just turn round and sneer "Is that all you've got boy".
So, Paul996, since I've ridden with you on the road, I can tell that they'd probably say the same to you.
Mind you, with your mileage, depending on how hard you are on tyres I would say
A rear Corsa III would last you 1 year +
A rear Diablo would last you 2 years +
A rear Strada would last you 3 years +
