Metzler Z8s anyone?

One problem I think I've found with the PR3s is their tendancy to "walk" when pushing corners. Have you found this? It's almost like understeer. It's as if all the extra grooves / sipes allow the tread to walk across the road surface - something I've not experienced on a conventional tyre (with just single water channels).

Try prodding and pushing the top of the tyre when it's off the bike (yeah, I know, maybe find another). It's a very soft carcass, which offers great grip, but also means the tyre can flex a lot under heavy pressure. Or walk as you've found.

Boss found this, switched to Z8's and been much happier.

Yes I get where you're coming from, can agree with that sensation of the tyre walking when pushing close to the limits. Personally I've only felt that being an issue on the racetrack. But hey, like I mentioned before, once my last set of PR3s are done it'll be a set of Z8s for me...just so I don't get too one eyed on Michelin
