Greenball Soft Turf. FEATURES AND BENEFITS: All weather traction; Smooth performance; Turf friendly drive; . OVERVIEW: The Greenball Soft Turf is an all season tire manufactured for lawn mowers and other garden equipment.The tire promotes great all weather traction. The tread design's flat footprint upgrades the dry, wet and light winter weather performance by allowing the Z-shaped tread lugs to find good grip on the terrain surface. The tread's optimal footprint and tread design also prevents hydroplaning by dispersing water and slush from below the tire's footprint. In this manner, the tire's terrain and turf surface contact is constantly upgraded throughout the year.The model ensures a lengthened and more comfortable performance. The flat footprint enhances the tire's even pressure distribution which upgrades the tread life. The equally spread out forces of acceleration, cornering and braking lengthen the tread life by preventing irregular wear formations across the tread area. The equal pressure distribution also increases comfort levels by providing a smoother driving experience.The Soft Turf guarantees a turf friendly performance. The high flotation tread design performs on the turf and terrain surface without damaging the turf and grass field. It guarantees a softer traction that does not damage the field during the tire's performance.This is a bias ply tire. Due to the tire's internal construction and size, it is possible that the tire will look deformed. Smaller bias ply tires do not have reinforced constructions that can keep the tire from deforming. The bias construction and the small tire's non-reinforced internal structure allow the tire to fold in when it is deflated or not properly inflated. This is not constructional damage or an issue; it is a normal occurrence with such tires. In such cases, the tire needs to be mounted and inflated to the proper PSI or, in some instances, an inner tube needs to be added. The proper PSI and the inner tube are able to maintain the tire's ideal shape, preventing the bias plies from looking deformed. This ensures their performing safety and durability.

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.
