I just wanted to write a quick follow-up. A couple of months ago we had a guest speaker from Tire Connection. For those who were not there, he talked about your tires, they may look good and have tread left. But if they are over 5 years old they need to be replaced. My tires were in this category. Last week at about 55 miles per hours the tread destroyed itself on 1 wheel. Chunks of tread were flying in every direction. Luck was with me and no damage was done, but control could have been lost with someone getting hurt. For $252 I got a new set of tires mounted. Are you taking a chance with your tires???
