I hit a construction sign yesterday on the highway. The wind blew it over and by the time I saw it there was nothing I could do, There was a car next to me so I could not swerve and I ran over the metal foot. It blew out my 2 driver side tires. I was close to a shop and they put 2 used tires on for $35 each. Now I am tring to decide if i put 2 of the stock tires on or buy 4 new ones. I have 16k on the tires now. Have you replaced the stock 15s with something else? I am in Michigan so it should snow, it might not but it should.
