Greenball Ultra Turf. FEATURES AND BENEFITS: Versatile performance; All weather controllability; Longer lasting tread life; . OVERVIEW: The Greenball Ultra Turf is an all season tire manufactured for lawn mowers and other garden equipment.The tire promotes great all weather traction and controllability. The tread design's S-shaped tread blocks with the special siping detail and the flat tire footprint work together to maintain the tire's road contact at all times. The tread's constant road contact boosts the dry, wet and winter weather road and turf gripping capability, while it also increases the steering responsiveness and driving stability. The stable structure and the quick and precise steering responsiveness upgrade the year round performance.The tread design ensures a lengthened tread life. The optimal shoulder pattern and the footprints even pressure distribution manage to prevent uneven tread wear formations. The equally spread out forces of acceleration, cornering and braking avoid irregular tread wear, while the durable wear-resistant tire compound slows the tread wear rate down, ensuring a cost-efficient driving experience.The Ultra Turf offers a versatile performance. The durable tire compound and the tire's stronger internal construction enhance its turf and pavement driving capability. The tread design offers a soft traction that does not damage the turf and grass field. On the other hand, the reinforced compound and structure do not allow damage to shorten the model's service life, while also maintaining the optimal tire shape that allows the tire to safely perform on pavement road surfaces.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.
