Hey all. I just bought a set of Bridgestone Insignia 200 SE tires for my '89 Fleetwood. She has 156,xxx miles on the clock and I thought a mention of that may help diagnose this issue: As I turn from any speed or shift from lane to lane at any speed over 10mph, the wheels feel as if they're bending. When I straighten the wheel to complete the movement, the entire vehicle has a slight shift or aftereffect. It's almost like pouring a cup of jello on a counter and then flicking it and watching it jiggle. It's hard to explain and hard to see from another driver's perspective. What could possibly be the problem?
