Trac-Gard N775. FEATURES AND BENEFITS: Longer tread life; Enhanced stability; Improved durability; . OVERVIEW: The Trac-Gard N775 is an all season bias ply tire manufactured for lawn mowers and garden equipment.The tire provides great all weather traction. The ribbed tread pattern and all season compound work together to increase the dry, wet and winter weather performance. The compound keeps its flexibility even in colder temperatures, while the tread design firmly grips the road surface in all conditions. The circumferential grooves channel water and dirt from the tire's footprint, ensuring the tire's constant road contact for a safer driving experience.The ribbed tread pattern's continuous center rib maintains its road contact at all times, increasing the driving stability. The tire's structure is stabilized against the driving pressure affecting the tires while they're in motion. The optimized road contact promotes a safer all weather performance. The optimized road contact and the square shoulder tread elements increase the tread life. They ensure that the driving pressure is equally spread out across the tread area, boosting the tread life by preventing irregular tread wear formations.The N775 features a bias 4 ply structure. The reinforced structure upgrades the tire's durability. It prevents deformation to the tire's structure under the driving pressure affecting the tires while they are in motion. The optimized structure improves the performance by ensuring even road contact at all times. The stronger structure also effectively resists punctures, ensuring a secure drive.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.
