All 4 tires have been warrantied 3 times. Goodyear will not warrantie them again so I had to replace them at my expense.
I had to balance and rotate them every 6000 miles, or my entire vehicle would shake at 60+ mph. Between all 3 sets, I only drove 100,000 miles, but the tires are 65,000 mile tires.
I guess 100,000 miles is good, even though it took 3 sets to get there.
