The new Alliance 778 irrigation tire from Yokohama Off-Highway Tires America Inc. features a unique, Y-shaped center block.
Yokohama Off-Highway calls the new feature "a revolution in irrigation tire tread design.
"The overlapping Y shapes in the centerline of the zero-degree lug pattern improve both traction and durability compared to traditional lug patterns."
“You are guaranteed to be operating in wet conditions with an irrigation tire, so you absolutely need great traction,” says James Crouch, national segment manager – agriculture and forestry for Yokohama Off-Highway.
“But you also want to minimize rutting and make sure every tire on every tower keeps itself clean, no matter which direction the tire is operating in.
"We completely redesigned the Alliance 778 irrigation tire to meet the very specific needs of farmers under irrigation," he says.
Under the overlapping Y-centerline is a tie bar that improves durability and service life.
And the company "developed a special ozone protection compound for the Alliance 778 to minimize the cracking that can plague conventional irrigation tires,” continues Crouch.
The ozone compound is also sunlight and water-resistant.
“As irrigation systems get more precise and water and power become even more precious, keeping irrigation systems moving reliably and efficiently with high-performing tires is more important than ever.”
The new Alliance 778 comes in three sizes: 290/85D38 (11.2-38); 290/85D24 (11.2-24); and 380/85D24 (14.9-24).
