hard steering - radials or bias ply

[carguybill]

My '34 is difficult to turn when not moving or moving slowly. I put a number of layers of polyethylene plastic sheeting under the front wheels and the steering effort is relatively easy so I'm assuming that the issue is the friction between the tires and the pavement.

I have original type bias ply tires on the car but am considering changing to radials for improved road handling but I wonder if the larger footprint of the radial tires would make the slow speed turning even more difficult.

Any ideas/comments?

Thanks
