I ride a GPX250 with stock Dunlop K630 tyres and after only 7800kms I need new tyres. Is this normal? Everything I have read about the K630s is that they aren't very good at anything but lasting a long time. My rear tyre is squared off, which I understand, but the front is good in the centre but down to the wear indicators to the left and right of it.

I think our roads are cambered to the left so water runs off, but my tyres are worn down on both sides. I don't understand how the front can be worn so much towards the sides compared to the centre when my rear is squared off.
