Sep 2020 purchased 6 Cooper Discoverer AT3 (LT235/80 R17) tires to replace OEM tires, mileage 12,885. On/around Sep 2022 while towing a 38' 5th wheel trailer, front end of truck started bouncing, mileage 26,334. Both driver and passenger tires where found to have tread separation. Replaced those two with same make/model new tires. All other tires where rotated and balanced. New tires went to inner rear wheels. On/around Aug 2023, once again while towing large 5th wheel trailer, front of truck started bouncing when turning to the left, muted vibration when turning to the right. Tire shop found passenger front tire tread separation again. This was one of the orginal 6 from 2020, mileage 33,762. Since 3 of the 6 tires failed I replaced all 7 (spare included) Cooper tires at my expense.

Bought truck brand new in 2019. Around 16-17,000 miles, I had to replace both front tires, the steel belt had shifted inside the tire causing a bulge and making the vehicle vibrate severly while transporting 3 horses (Approximate trailer w/ horse weight = 14000lbs). I brought back to the dealership, replaced with the same brand as I was unaware of these issues. I now have 36,000 total miles on my truck and about 19,000 miles on this new set and the issue just occurred again. There is something wrong with this brad of tire that these belts continue to shift inside the tire and will eventually cause larger issues. When the event occurs, everything inside the vehicle begins to vibrate and no question impacts the suspension components.

Front passenger side tire had large ballon form on inside sidewall causing uneven rolling. LT 235/80/17. Luckily I wasnt hauling my 5th wheel Toyhauler when this developed I imagine the rest of the tires on the vehicle are faulty as well. Lives are at risk with these tires on my vehicle
