So, I realize this thread is 9 months old, but wanted to share. Had 4 of these Sentury tires put on my mother in laws 2005 Camry in 2019. She's 80 now and drives about 1500 miles a year (not kidding.) We also had some balance issues and she recently had a vibration. Discount Tire said front tires were coming apart and needed to be replaced. Exterior of tires looked absolutely fine, it was internal I guess. So, she still had some warranty left. She had them rotated and balanced periodically in the store and had several nails removed over last 5 years, so not sure if it's where shes driving or what on the nails....)
Instead of replacing 2, I asked store manager (I was on phone with them, I live in SC and she is in Florida) and he said 4 new tires (also Sentury) would be $235 out the door (pro-rated warranty left on old tires.) So, went ahead and did it.
I really wouldn't recommend them for the average daily driver (I can't imagine them lasting very long for someone who drives 10-15K a year), but for her use, if she can get another 5 years, they are fine. For $235, we couldn't complain.
