Trac-Gard N766. FEATURES AND BENEFITS: Terrain versatility; Enhanced durability; All weather traction; . OVERVIEW: The Trac-Gard N766 is an all season tire manufactured for lawn mowers and garden equipment.The tire offers excellent all weather traction. The tread pattern features a symmetric tread pattern that consists of S-shaped tread blocks. They manage to find good road grip in all weather. The symmetric tread design enables the tire to maintain an even road contact in dry, wet and winter weather and to ensure exceptional road gripping ability. The wide grooves channel water and slush away from the tire's footprint and actively resists hydroplaning when driving on road.The symmetric tread pattern ensures a longer lasting tread life. It manages to evenly distribute the driving pressure along the tread area to prevent irregular tread wear formations. The resistance of irregular tread wear greatly lengthens the tread life and the tire's usability. The special 4 ply internal structure reinforces the tire's structure and manages to prevent damage from causing harm to the tires casing. Punctures are avoided in this manner, further extending the tire's longevity. The 4 ply structure also improves its load carrying capability. In this manner, the tire is able to carry and withstand heavy loads with ease, while also maintaining its optimal shape. This capability allows the model to be used for residential and commercial purposes with ease.The N766's tread design enables the tire to be used both on turf and on concrete, which improves the tire's versatility and usability greatly. The tread design allows the tire to safely perform on-road, without the concrete causing harm to the tire's casing. In other words, it prevents chipping and cracking. The symmetric tread design softly performs on turf, without damaging the grass field.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.
