When harvest rolls around there's a lot of talk about big grain carts rolling through fields and the compaction they cause, but ever consider that combine?
The folks at Michelin have been looking at combine tires for some time, and this year they're rolling out the new CerexBib radial that offers a high-flexion option for those big harvesters.
"When you look at the new heads on larger combines and the weight those machines carry, we saw an opportunity," says Michael Vandel, marketing segment manager, Michelin North America. "With this new high-flexion technology you can increase the load on the front of the combine by 20% without the need to add air pressure."
Michelin was the first manufacturer to introduce the IF and VF tire classes, first pioneered for the big Challenger MT900 tractors. That same high-flex sidewall design is now available in two different CerexBib tires, one specifically for the front of the combine and one for the rear.
"If you can lower the pressure on the tire, you improve the footprint and increase traction," Vandel notes. In addition, the company looked at the issue of stalk damage to tires, and has shaped the tread in a way that pushes stalks aside. As a result the company expects these new tires to wear better in the field.
