Does anyone know the status of the Michelin Pilot Road 2 tires? Is Michelin discontinuing/phased them out because of the PR3 and PR4 tires? I tried to buy a set of PR2's this spring and couldn't find a full set anywhere. When I look for them now the front's seem to be out-of-stock everywhere and only a few places have the PR 2 rear. I'm running a PR3 front and PR2 rear now. Because of the price differential I?d much rather be running PR2?s on both ends. For me they?re the best tire I?ve ever put on a bike.
