At the current moment, in the size I want, 255/40R19 there is nothing avail for the MPAS4. Theres still stock on the AS3+ which is discontinued. But nada for the 4. Not sure if this is due to Covid rubber supply issues? Plenty of stock currently for the DWS06+
And worried if I wait till next year, maybe nothing of either availble. So buy now or later.
Sidenote: the AS4 is the OEM tire for the C8 Corvette
