Wanda P512. FEATURES AND BENEFITS: Turf terrain traction; Enhanced controllability; Upgraded durability; . OVERVIEW: The Wanda P512 is an all season tire manufactured for lawn mowers and garden tractors.This model offers a better turf terrain grip with the special chevron tread design. These tread elements, along with the groove pattern, optimize the tires soft and loose terrain grip. Better traction guarantees its consistent forward motion at all times. Additionally, soft traction minimizes the pressure placed on the driving surface, preventing damage to turf and grass field surfaces. Their combination enables the tires exceptional driving safety levels.The chevron tread design maintains surface contact at all times. As a result, the tire manages to significantly improve its steering responsiveness and driving stability throughout the drive. This promotes quick and precise steering responses to the drivers commands, while the structure is secured against driving pressure. Their combination helps to enhance its controllability and maneuvering.The P512 was designed with a bias-ply internal structure. As the tire does not deform, it is able to maintain the ideal tire shape under load and driving pressure. Since the tire does not deform under load and driving pressure, it is able to effectively enhance its load durability.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.
