Hi all, Background: I live in Switzerland and though we've been having the best summer in decades, I'm already planning my tire choice for the autumn/winter. I ride a lot in winter (my ZX-6R 636 is my main mover:-). I've heard people telling me that the best choice/compromise between wear and grip is to use a sport tire in front (eg. Pilot Sport or BT 011/010) and a sport tourer tire (eg. D 205 or Metzeler ME Z4) at the back. I read two comparison articles in a german magazine: one about sport tourer tires (not available online anymore) and the other about purely sport tires ([URL]http://212.86.161.2/MRD/Reifentest2001/9_0/c_9_0.stm[/URL]). Looking mainly at the wet grip characteristics, it seems the Pilot Sport and the ME Z4 are the best in each category. My question is quite simple :-): Do sport tires "stick" better in wet/cold conditions or are sport tourer tires better for not needing warm-up time to stick (keyword: silica)? Or put another way: Should I get a ME Z4 for the front during the winter or will the Pilot Sport still be better at cold conditions/not warmed-up? I've been using Pilot Sports since I started riding (half a year ago). TIA, Marcio Cordero
