Alliance Unveils Latest Increased Flexion Harvest Tire

March 19, 2018

Alliance Tire Americas Inc. (ATA) has designed its new Agriflex 372 IF 1250/50R32 CFO tire, which stands nearly seven feet tall and more than four feet wide, to minimize soil compaction.

Each of the huge tires can carry up to 22,480 pounds at an inflation pressure of just 46 psi, which helps reduce yield-limiting compaction that can be caused by combines and grain carts, according to James Crouch, agricultural marketing specialist.

ATA says increased flexion (IF) sidewall technology and precision engineering is responsible for the tire's high weight capacity and low inflation pressure.

"The new 1250/50R32 size for the Alliance Agriflex 372 IF reflects not only an impressive manufacturing feat, but also demonstrates Alliance Tire's commitment to offering low-pressure solutions for every application on the farm," Crouch says.

With an ever-growing line of IF, VF (very high flexion) and flotation tires, Alliance can help farmers protect their fields from soil compaction all season long and on every piece of equipment from the planters, sprayers, combines and grain carts, according to Crouch. “That ensures that a farmer doesn't prevent compaction with his tractor and end up doing damage later with some other tire."

Crouch notes that Alliance has also added an IF 1050/50R32 size to the Alliance Agriflex 376 lineup. He points out that IF tires offer users a choice of benefits:

  • 20% greater load capacity than standard radials at the same inflation pressure, or
  • the same load capacity as standard radials at 20% less inflation pressure.

Both of the new tires bear the "CFO" designation, which stands for "cyclical field operations." That reflects special design and construction to withstand the cycles of loading and unloading—and shifting weight—experienced on the go during harvest.

Crouch explains IF and VF technology in one of Alliance Tire Americas' new "ATA Tireside Chats" videos, which can be found online.
