Ok Gents here is my situation. i have 08 metallic grey #6 about a week old and it has 323 miles on it. its snowing yesterday till this morning here in CT and i felt my prius is not performing really well on snow. i went to my local townfair and ask the michelin x-ice. my first choice actually is the TT's but the local goodyear dealer here dont have 185/65/15 and i insist the 195/65/15 and they are not recommending to put on my prius because i might lose the warranty etc. and so on... i went back to townfair and they can install the x-ice asap. my question now is: is the X-Ice is just really for ice/snow only? i still preferred the all season tire but no size for TT's which is better X-Ice or Comfortreds?
