I realize that tires are the only thing between me and my family and the road! So with that being said the tires are fantastic and give me a true peace of mind, I know that no matter where my family or I am I will be able to drive on the tires if air loss occurs for 50 miles at 50 mph, and get this tire repaired, and if it cannot be repaired Bridgestone has a warrenty on the tire for a free tire for 12 months/12,000 miles. I don't have to get out of my car to put on the spare. My wife usually drives this vehicle which to me is another peace of mind. These are an awesome idea from Bridgestone! They also ride very smooth and handle excellent and are very quiet tire. I won't be able to tell you how they ride in the winter, because I was smart enough to invest in snow tires. But I would highly recommend these tires to anyone who would like an extra layer of safety built into them, Run-Flat technology.
