Seven Reasons to Consider Radial Tires

Radial tires 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.

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. With 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 the 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 chance for “pinch flats” and loss of bead/rim seal in difficult terrain – even at much lower tire pressure levels.
