These are the WORST tires I have ever purchased. They barely lasted 39,000 miles. My husband has ASE certification and is very thorough in maintaining our vehicles. Every Saturday he checks fluids and tire pressures and this week he noticed a large crack in the sidewall of one of the tires. The crack ran around the entire sidewall roughly 1/2 way between the rim and the tread (through the BF Goodrich and "touring ta") I thoroughly photographed the tire to show that there was NO damage at all to the sidewall other than the crack. I took the car to my local tire shop to see about replacing it under the warranty and was told that the tire was definitely defective and that they don't stock this brand because it is not very reliable. I ended up buying 4 tires of another more reliable brand.
