Alliance (Yokohama) 320. FEATURES AND BENEFITS: Versatile terrain traction; Field friendly performance; Upgraded load durability; . OVERVIEW: The Alliance (Yokohama) 320 is an all season tire manufactured for tractors.The tire utilizes the tread design to improve its performing traction. The center zigzag ribs and the shoulder block pattern upgrade the soft, loose and uneven terrain traction, while also boosting the on-road performance safety. The tread's optimal surface contact upgrades the deep mud and loose dirt traction, ensuring a secure off-road drive on different terrain surfaces. The self-cleaning nature of the tread prevents mud and snow from blocking the surface contact, greatly improving the overall off-road performing ability.The model guarantees a field friendly performance. The aforementioned stronger soft traction allows the tire to prevent soil retention by optimizing the high flotation capability. Field retention ruins the soil quality with excessive traction, as it loosens up the ground the tire is used on. By avoiding it, the soil is able to secure its healthy crop growing ability as it keeps the soil quality.The 320 increases the load and driving durability. As the tire does not deform under the load pressure, it is able to securely carry and withstand heavy loads with ease. The reinforced internal structure keeps the ideal tire shape under the load and driving pressure. In this manner, the nylon cord casing promotes a safer load capacity throughout the performance. This specific tire model features a BIASED ply construction. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
