2 years ago in 2012, I had 2 tires separate the tread in route to Florida during the same trip ... One in a rain storm in Baltimore... One at 9:30 at night on 95 in South Carolina... Both times we were at 65 or less...one was e street side rear.. The other was curb side rear...
No major damage.. Both were date code 08 from USA ..I found a dealer about 5 miles from us in the morning that had 4 with a 2012 date code... I took all 4.. Put them all on and the best non blown went under as spare..
