We recently replaced (all 4) the tyres on our CX5. I had always moaned about the ride quality of the OEM ones (seemed excessively harsh in the rear) and even the subsequent set that we were now replacing suffered from the same. I had put it down to the suspension settings. But replaced them with the Momo M9 (https://www.hyperdrive.co.nz/product/107241/momo-italy-m9) tyres and was very surprised that the harshness has all but gone. The ride quality is now great; its not floaty or anything, still nice and responsive, just not crashy in the back. The only downside is that they are a bit noisier than the ones we were replacing, but imo a far better replacement.
Really happy in the end; somewhat surprised. Too soon to tell how they will wear, but overall really happy.
Just my opinion on our recent run :)
