I had a 1994 Ford Probe GT and last year I had new tires put on it, but the car would vibrate above 60mph. I had the Goodyear Tire place check the balance 3 times with no luck. Then I went to a place that had a road force tire balancer and they told me the 3 out of the 4 tires were bad. So i went back to the Goodyear place and told them about my findings from the other shop. Well, the did the road force test too, but only replaced 1 tire. It helped, but it never did drive perfect. The point of this story.......wait, what were we talking about? lol. Best of luck dude. :drive:
