Bias and radials?

[Keith Tedford]

Years ago I had a '79 Impala and I was running radials. Come winter I put on a set of bias ply snow tires. It was fine until I got on an old highway that was rutted from many years of too much traffic. The car would literally shoot from one side of the rut to the other. Scariest ride I ever had. With radial snows it was fine and the ruts weren't even noticeable. Perhaps different vehicles react differently.
