Deli S-365. FEATURES AND BENEFITS: Turf friendly performance; Longer lasting tread life; All weather traction; . OVERVIEW: The Deli S-365 is an all season tire manufactured for lawn mowers and garden equipment.This model provides great traction with all season compounds and the ideal tread design. These elements work together to optimize the grip on various terrain surface conditions. The tread design, with a wide shoulder pattern, boosts the grip on grassy surfaces, boosting the tire's performance. The special tread design prevents loss of traction on versatile terrains, while the all season compound keeps the rubber flexible in different temperatures.The special tread design also guarantees the tire's turf-friendly performance. The wide shoulder design and the special tread pattern enable traction, without it harming the turf surface. They promote the model's soft traction and guarantee a delicate contact between the tire and the turf surface, in order to not damage the grass field. This makes the tire perfect for lawn mowers and garden equipment.The Deli S-365 also offers a longer-asting tread life. The ideal tread design and the flat footprint lengthed the tread life, by preventing irregular and premature wear formations along the tread. This footprint allows the tire to evenly distribute driving pressure across the tread, which significantly increases the tread life and usability.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.The photo is a representation of the tire's possible deformation, it does not represent the specific tire model, size, tread pattern and application.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.
