These tires were new on the car when I bought it I've put 28,000 on them in a year. They started making noise and vibrations after about 10-15,000 miles. I had them rebalanced and it helped with the vibration. Recently they have become even more noisy and vibrating more. After checking them closely today they are all wearing strangely and one of them isn't even round any more. Not just a broken belt it actually looks like an octagon. This is my third vehicle that has had General tires on it and I haven't had very good luck with any of them. Never again!
