My tires are almost 6 years old and after 35K miles the tread is not officially worn out (<2/32) but I have not been able to get very good traction for the last 10K miles. I easily spin the wheels even on dry pavement and with winter approaching i think i have to replace them to be safe. I am very disappointed since the product features sounded execellent and my tire shop highly recommended them. After reading the warranty info i do not see any way that BF Goodrich will stand by the tires. There is no warranty claim for unsafe tires due to lack of traction. For tread warranty claims who keeps the documentation that proves the tires have been inspected and rotated every 6-8K miles? All 4 tires have even wear and have been rotated and the wheels have been kept in alignment.
