Find someplace other than Mr. Tire on Mountain Road in Pasadena Maryland. They installed four new tires on my van, and the van then started vibrating when I drove it away. I took it back to them and they re-balanced the tires, but then the car still vibrated some. So I went there a third time and left the car with them overnight. The next day they said they had done everything they could, and if it still vibrated it was not the tires causing the vibration. I drove away and the vibration was better, but still noticeable between 55 and 65 MPH. I was fed up with them and never went back, and drove the car for 17,000 with the vibration occurring at highway speed. Well, this morning a rear tire exploded while I was driving on a highway. I put on the spare, and lo and behold I now have no vibration whatsoever. So it was that tire that was defective. I went back to Mr. Tire today to tell them what happened. They wanted to sell me a new tire. Do yourself a major favor and go elsewhere.
