I got just short of 12,000 from my first set of PR2.s had Michelin in to have a look as they were still not illegal, just a tad squared off, even the front had a small flat spot. put a new pair on and 5,000 odd later, the rear is just starting to get a slight flat, so looks like these,ll do similar mileage. must add that I ride solo, but briskly (according to Heddlu anyway) and several times a year with full luggage and camping gear.
