The new Michelin Road 6 tire ... better than the Dunlop Roadsmart 4?

[Grumpy Goat]

We had some cupping on the Pilot Road 2, 3, 4 and 5.
The front 5 had the shortest life of any tire that I can remember.
I bet they use a harder compound on the center of the front tire in the 6 series.

I think we had cupping with any of the dual compound tires we have tried.
The Dunlop RS3 has been the best with very little cupping.

This has been my experience also - RS3 little to zero cupping, PR4s lots of cupping. Never tried any other Michelin Pilot Road tire. Also the RS3 has the best wear characteristics for me thus far (and I have not yet tried the even better RS4). Surprised that the Road 5 had the shortest lifespan for you.
