They are a quiet tire. I've had a set since 11/19. I asked the OP which model being that several are offered in this size. My experience is as follows :
Compared to General Altimax RT-43 that these replaced: Quieter, handle a bit less sharp, overall can ride rougher depending what pressure you like to run ( I had to drop cold pressure from 36 psi to 34 for better ride but lost at least 1-1/2 mpg local, around town). However did get 31+ mpg highway @ 36 cold before I lowered pressure but it rode hard hence dropping to 34 psi. In their defense, I am now satisfied with the ride and definitely do not miss the constant noise level of the RT-43's. Also, to me I got back that feel of the tire being better connected to the road (road feel?) that the RT's didn't quite have. Can't comment on snow traction on either tire since I never got a good chance. Wet and dry traction better than RT's, especially wet traction. After a few years the RT's lost some wet traction and spun out easier. After having these I don't plan on going back to the RT's and may try the Continental's (LX25) that seem to be gaining popularity. Overall, these CS5's aren't a bad tire at all and the possibility exists of buying them again when the time comes. That's still a couple years down the road as these get further evaluated. Just thoughts off the top of my head on this foggy (mentally and environmentally) morning. Over and out.
