8. Sprayer tires
Until recently, farm tires were divided into two categories: tractor tires and implement tires. But in recent years tire companies have introduced tires specifically designed for the speed, roading and load requirements of self-propelled sprayers. The Goodyear Ultra Sprayer Tire, launched by Titan Goodyear in 2007, was the industry’s first sprayer-specific design, featuring wider lugs for better wear on the road and superior traction in the field. In early 2010, Goodyear expanded the design to include additional sizes for the sprayer market.
In July, Michelin launched a sprayer-specific tire called the SprayBib radial, designed with VF technology and a D speed rating, making it capable of carrying 14,330 lbs. at speeds up to 40 mph.
Alliance has a 380/90R46 narrow sprayer tire rated for 40 mph along with a 600/50R22.5 radial flotation tire under development that can travel 50 mph. For 2011, Firestone is introducing two sprayer-specific tire sizes (IF380/90R46 and IF380/105R50), both with AD2, or IF, technology for increased load-carrying capacity.
