Titan Tire Corp. expanded its Goodyear Optitrac line of radial agricultural tiresm which feature a self-cleaning tread action and an improved mold shape that helps create a smoother ride, the company said.
 
“We designed the Optitrac with a 25% deeper lug compared to conventional R-1 tires,” said Jeff Vasichek, vice president of sales and marketing. “This design provides for more aggressive traction in heavy-tillage applications. The new design also offers longer tread wear while the reinforced bead area helps the tractor withstand the forces of higher-torque applications and allows for increased loading.”  
 
A 45-degree tread lug angle promotes more open space on the lugs for better cleaning and improved traction, especially on soft, moist soil. The lug configuration and mold shape was modified, helping to enhance handling and performance in the field and on the road. These design features also result in a smoother ride, thereby reducing operator fatigue, according to the tiremaker.  
 
Sizes include a DT800 for narrow row crops, DT806 with a standard 85 aspect ratio, DT812 with a 70 aspect ratio, DT818 with 65 aspect ratio, DT824 in larger volume 540 to 800mm widths, and a DT830 super large volume in 900mm and up widths. Additional sizes will be introduced in the coming months.
