Mike, I am in the tire business, so I may be biased (pun intended).
Armstrong Tire has a film of 2 identical Ford tractors(150 HP, I think), one with bias ply and one with radials, both pulling the same size chisel plow (seven shank, maybe),same depth, same gear, same RPM, same weighting . Everything was to be the same. The radial tired tractor would beat the bias ply tractor through the field by a good margin due to less slippage.
Then they ran the 150 horse bias tractor against a 135 horse radial tractor, again both had the same 7 shank chisel. Radial tractor still outpulled the bias due to less slippage.
Then they added 2 more shanks to the 135 horse radial tractor and left the one alone on the 150 horse bias tractor. Guess which one won. The radial. That part of the film would never have been shown if it hadn't.
