I'm using xm2 and like them very much. Quiet, comfy, decent wet/dry grip, good looking and they last and last. Last used xm1 and they lasted me till 70k mileage! (also not completely botak, just almost reach the wear indicator only...had to change cos used for almost 3years liao!) Xm2 seems to have the same long wear. Only need to rotate tyres every 20k instead of 10k as compared to others. Clocked 35k already on xm2 and they still look new :). Go 4 it !!!
