I have a question about tires. As some of us have had our mustangs for a really long time like myself. My mustang is a 2006 with 26000 miles on the original set of tires. If you research this on any website or forum the opinions are all over the place. Some say 6 to 10 years some say if the tires don't have any side wall cracks there good. However I am sure after 15 years the rubber will start to stiffen there by changing the flexibility of the tire itself... Your thoughts will be appreciated... Thanks
