He Replaced His Tractor Radials With Bias Ply Tires
"My Case 930 tractor had a problem. It needed duals to take advantage of the horsepower but if you put duals on you would break the rear axles," says John Ruff, Logan, Kansas.
  "When the radials on the tractor went bad, I did some serious thinking for several months before I decided to put on a set of Goodyear Dyna Torque II bias tires without fluid. I had previously put Dyna Torques on my two smaller tractors with no fluid and found they made a big improvement in the performance of the tractors. That wasn't as much of a gamble as both were much smaller, lower horsepower tractors that were originally fitted with bias tires. The Case tractor, however, was much more of a gamble.
  "I've run this tractor for more than 35 years so I know how it runs. As soon as I let out the clutch on the new tires, I could tell the difference. The tractor started moving faster and the difference in the field is very noticeable, too. There's less slippage than I had with the fluid-filled radials. When the going gets tough, the governor response is very fast and is noticeable in the exhaust sound. I don't know what the impact is on fuel consumption yet but I know the tractor can do more work now.
  "Unfortunately, Goodyear is phasing out the Dyna Torque II bias tires. I don't think the company realizes how good these tires are. Thanks to the short bar/long bar lug design, there's more lug area in contact with the ground than with V-shaped lugs. They also clean better in mud. Bias ply tires with V-lugs might not work as well.
  "I can see why no one has tested Dyna Torques without fluid against radials with fluid, so the company doesn't know how well that works. Hopefully, someone at Goodyear will figure that out before they drop what has to be the best agricultural tire the company has ever made. They wear well and cost less. It's also nice not to have to worry about the rims rusting out."
