I put a set of PR2s on 15K miles ago. Got great mileage, excellent grip for my riding style, and very predictable feedback and slippage the few times they slid. The rear didn’t start squaring off until 13-14K miles, and the wear bars were showing soon after…Tony can attest to how well they held up. The front still has life left. I’m looking for a new rear and am considering the PR3. Clearly it’s supposed to have better wet grip and longevity than the PR2, but what about dry grip? I see on the
Michelin website that the PR3 has the “soft” compound in the center 50% of the front tire, while the PR2 has the soft compound in the center
60%. Does that mean the PR2s are still the more aggressive tire? If so, I’ll take the PR2 at the cheaper price. 15K miles is plenty long enough, and I don’t push my tires to the slipping point in rain anyways…
Also, the graphic showing the bend/give of the PR3 rubber (claiming it helps break up the water tension) makes me nervous. Maybe that’s good in the rain, but it seems like it would cause the tires to act weird when dry.
