Caster may have become + instead of - ???

The bias ply tire has a lot of foot drag. MEANING that as the car goes faster and faster the contact surface of the tire to the road moves BACK toward the rear of the car. THIS IS THE SAME as jacking more negative caster into the front suspension.

The radials have near minimal foot drag. So the radials simulate closer to zero or positive caster.

Negative caster causes steering hunt. Positive caster offers resistance to road and wind compliance thus reduces or eleminates hunt.
