Looked at them today and noticed no tread on two of the bands on 3 tyres the forth was replaced after 2k due to a puncture!.... That has tread all over!!..... The wear is even on all tyres! Is it a characteristic of the tyres?Got them on mine after the Pirelli Nero Zero things were noisy and the fronts are wearing relatively quickly and there appear to cracks in the tread grooves on the corner of the sidewalls. What about you?
