Wanda P605 Stud. FEATURES AND BENEFITS: Enhanced controllability; Turf terrain traction; Upgraded durability; . OVERVIEW: The Wanda P605 Stud is an all season tire manufactured for lawn mowers and garden tractors.The tire features an ideal knob tread design in order to maintain its surface contact. The stud pattern improves the tire's road contact, offering better controllability. As a result, the model is able to effectively upgrade its steering responsiveness and driving stability. Faster and more precise steering responses are guaranteed with this model, while the structure is secured against driving pressure affecting the tire. This combination allows the tire's safer driving experience.The tread pattern utilizes its stud-shaped knobs and high void ratio to enhance traction. These tread elements work together in order to increase the tire's soft and loose terrain grip. They ensure the model's consistent forward motion, without harming the driving surface. In other words, the tread provides the necessary traction to perform on turf fields, but it does not damage the grass or turf area with its excessive traction. As a result, the tire guarantees a field-friendly performance.The P605 Stud sports a bias-ply internal structure. This construction does not allow the tire to deform under pressure. In other words, it is able to effectively enhance its load-carrying capability. Better load and driving durability make the tire perfect for larger lawn mowers and other types of garden equipment.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. There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to Priority Tire by the tire manufacturer.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.
