I changed from original Toyo to Hankook Optimo (width 185mm) 1.5 yrs ago. Just changed again to 195mm width Optimo 2 weeks ago. It feels more stable with this 195mm width. Wet weather grip is good. Just came back from Genting, high speed performance is good. BTW, after 1.5 years still a fair bit of thread(flower) left, but for safety reason in Malaysia, i changed it.
