The summer tires on the rs and ss package cars is not effected by this bulletin there is no set minimum storage temp for the 20" pirellis so they can be shipped year round your all seasons might allow you to drive a little bit safer between 40 and 20 but in the end they are not snow tires, and they do get harder sooner than a dedicated winter tire would/
