The ride of the M/S² is similar, if not better than the CTs. The M/S² is a little stiff due the threadwear rating, the ride is smooth but a little stiff, a little bouncy at times, like a truck which the T4R is. The ride is good and better than I expected.
The CTs were the best wearing tire I have driven on. They did not bald on me and after 62000 miles with rotation every 5000 Miles, there was enough tread for another 5-10K miles.
The M/S² is about $40 cheaper per tire than the CTs which was another consideration. If properly rotated, I should get 80K miles from the M/S² easy.
