The tires are pretty slick in the cold fog we've been having lately. I recently had my car serviced and they set the tires to around 42 lbs. The rear end was quite lively until I dropped the tire pressure back to normal. The car is great but I may re-think the tires next Winter. I find myself being very careful during the early morning commute.
