Don't know if this is old news but I read there was a recall on these from tires made last spring April 2004. It was first noticed that people were complaining about vibration but they found concerns regarding potential tire separation.

I read here that some members had experienced issues re: imbalance on these. Check it out.

September 30, 2004
BFGoodrich is recalling 46,000 tires carrying the BFGoodrich, Uniroyal, Liberator, Medalist, Phantom and Prospector brands. The company said they do not perform to company standards.

There have been no accidents or injuries reported and no property damage claims filed but the company said there may be similar performance issues with up to 3,500 tires, representing six tire brands. All recalled tires will be replaced free of charge.

The recalled tires have Department of Transportation tire identification numbers which begin with DOT BF and end with the last four digits 1504 or 1604. The DOT codes are found on the inner or outer sidewall of the tire just above the wheel rim and are printed in small type. There are no issues with tires manufactured outside of these DOT weeks.

Consumers should call BFGoodrich Tires at 1-877-788-8899 or Uniroyal Tire at 1-877-458-5878 or go to their tire dealer for a free inspection and replacement.
