⋯ As for the Michelin Premier. Well i did "played" with it in store. Sidewall are kinda soft ( i know once inflated it will get harder). I was able to easily bend the sidewall with 2 fingers and the thread blocks wont stay quiet on the long run. after a full year i'm expecting theses to be really noisy. That expanding center grooves technology and the additional grooves on the side wall that will appear as the tires wear down will raise the noise (additional zones of compression/decompression). Also ask the tech if he had one mounted on wheel and he had a set about to get installed so we went into the garage area and "played" with it again. Sidewall are not that hard, also another tech on site told me they are like all Michelin tires, balloon effect, meaning softer overall. That the only thing i can point a finger at for Michelin. Squishy balloon tires. Everything else is fine/great.
I do prefer hard tires in summer. It mean harsher ride but that the price to pay to get a little more cornering support and less rollover.
Also rubber thread was really soft, usually really soft rubber either wear fast or get very hard after a few year and tire noise get very loud.
