Tires Out of Balance or Steering & Suspension System Malfunction.
Pay serious and immediate attention to vibrations. The solution could be as simple as rebalancing your tires, but it could be as dangerous and complicated as fixing your steering and suspension system. Visit your local authorized BFGoodrich Tire dealer at the very first sign of vibration or “shimmy.”(You can find a dealer near you by using the Dealer Locator to the right.) If rebalancing doesn't eliminate the vibration, have the alignment and/or suspension system components checked.
