how on earth can you give an honest and comprehensive appraisal of a modern tyres grip when your getting 5000+ from a rear ........you are riding well within the limits of that tyres capabilities regardless of whether its a sport or touring tyre.
As has been said so many times before on this subject, depends how ya ride ,where, and what you want the tyre to do
What I find bemusing is how you can get a modern tyre to 'squirm' when your getting these kind of mileages ........must be something wrong with set up, pressures.......coz you're sure as hell not giving the tyre a hard enough time to make it lose grip ........unless your riding soaking wet diesel splattered roads.
Michelin pilots, bt023, or similar sport touring tyres should give ample mileage and grip for standard use maybe even Maxxis but if you want grip, ie your stepping the bike out every where and its constantly squirreling and tying itself in knots you need a softer sportier tyre, 2ct, conti ra2, diablo etc.
Read the reviews but be prepared for more bullshit than anti wrinkle cream ads.
its a mine field ...good luck
