Radial Pivot Tires Provide Rugged Alternative to Other Options

If you’re looking for ways to reduce tracking and cut maintenance costs, you might want to consider adding radial tires to your pivots.

“Radial tires are a high-performance alternative when compared to the traditional pivot tire options,” said Christopher Higgins, Zimmatic Global Product Manager at Lindsay Corporation. “While they cost a bit more than a bias ply pivot tire, the benefits of radial tires on pivots are more than worth the additional cost.”

Higgins said that radials have a wider, flatter profile than the rounded construction of bias ply pivot tires. That means more surface contact area in the wheel track and better flotation, as well as fewer rutting and wheel track depth issues as the season progresses.

Other benefits include:

  • Because of the wide, flat profile, the wheel tracks left by radial tires are much easier for equipment to drive over.
  • Radials generally run at much lower air pressure (15-17 psi) than bias ply pivot tires. Because they have strong, flexible sidewalls, they can support the load of the pivot – even at these lower air pressures. This allows more contact area and increased traction in difficult conditions.
  • Radial tires provide the most compliant tracking and smoothest rolling characteristics of any pivot tracking option, leading to less torque being transmitted back into your pivot driveline and tower span structures.
  • With rugged construction, radials are about 80 percent more resistant to cuts and penetrations in the tread area than bias ply tires.
  • If a tread face or puncture does occur, a radial tire is much more likely to be repaired and put back into service.
  • Radials have a much tighter bead to rim spec than bias ply tires, which reduces the change for “pinch flats” and loss of the bead/rim seal in difficult terrain – even at much lower tire pressure levels.

“I tried other tires, but nothing seemed to work,” said Nebraska grower Chad Kuhlman. “The radials were able to keep the pivots going later in the season when the tracks normally get deep.”

These tubeless radial wheelsets come with an 8-year limited warranty and are available in 12.4’ x 38”, 14.9” x 24” and 11.2” x 24” sizes.
