Most older beam-axle pickups -- like my Studebaker and the '37 Chevy i once had -- mount the axle on two stout leaf springs. Does this increase the likelihood of "shimmy" at speed?

My Studebaker came with 6.50 x 16 bias-ply tires mounted on split rims. i'd like to mount radials if i could find some modern wheels (infinitely lighter!) that match up with my six-lug, 14-inch drums. That in itself should be a huge improvement in handling.

God's Peace to you.
