Just had the Bridgestone RE960AS Pole Position tires installed. Holy Mackeral, what a difference compared to the Dunlop Runflats! Granted, the Dunlops were getting pretty worn (on the back at least), but the tire noise is now gone! Can actually hear the engine now -- a definite change for the better. Tracking seems much improved also -- less bothered by ruts and grooves in the road.

It's raining here today, and I don't want to push the tires yet until they seat properly. So from a purely comfort standpoint at this point I'm greatly satisfied. We'll see how it works out from a performance standpoint as time goes on.

Thanks again for all the comments to this post.
