I had vibration issues at highway speed. I hardly ever drive that fast, everything is within two miles from my house. Had my tires balanced at one garage and they charged me for it and said everything would be fine. A few months later I had to make a long commute and thought my truck was going to shake apart. Took it to them the next day and it ended up being a broken belt in my tire. They matched the brand of tire I had on my truck and had it ready to go in a few hours. Fantastic! It hasn't driven this smooth since I bought it. Price was spot on too!
