When exactly should I be changing onto my summer tires again? Today it was 85 (ish) with a low of 45. Tomorrow has a high of 60 and a low of 37. I'm sure 85 isn't going to be the norm for a little while, but is it bad for the winter tires to drive at that temp? Since it's Kansas there is the distinct possibility that we could either have a massive heat wave or blizzard by tomorrow so I'm not real sure how to play this game...
