Just wondering what sort of K's you get out of your sports tyres? I commute daily on a 2002 Fireblade and occasional weekend ride, not one to shred and ball up the tyres on the road. I have run Dunlop and Bridgestone Sports tyres and generally get 4,000 to 6.000 k's usually 2 sets per year, I ran Bridgestone Sport Tourers and clocked up 12,000 k's with minimal loss of grip for my type of riding, noticeable in the wet at the lights. I fitted a set of Michelin Pilot Road 2CT (Sport Tourers) in late 2008 and have since clocked up 18,000k's with still an estimated 5,000ks to go, simply amazing! I have a little less confidence in them than I did the Bridgestone Sports that I had prior to these but to be honest these tyres haven't given me reason to doubt them, it's just a feeling I have. Kev.
