RubberMaster S-Turf. FEATURES AND BENEFITS: All weather traction; Enhanced controllability; Turf friendly performance; . OVERVIEW: The RubberMaster S-Turf is an all season tire manufactured for lawn mowers and other garden equipment.The tire promotes great all weather traction. The all season compound and the detailed S-shaped tread block pattern, with the siping design, increase the dry, wet and light winter weather performance. These elements maintain an optimal grip on the road surface throughout the year and ensure a secure driving experience. The upgraded road design ensures a year round safe performance as the tread boosts the tire's soft and all weather traction.The tread pattern and the rounded shoulder design increases the contact between the tire and the road surface. They enhance the steering responsiveness and the driving stability by closely following the turf surface throughout the tire's performance. The rounded shoulders improve the cornering ability as well, as they increase the grip, without damaging the turf, in maneuvering situations. The better control over the vehicle ensures a safer drive, in all conditions.The S-Turf offers a turf friendly performance. The S-shaped tread blocks and the rounded shoulders maintain the tire's turf contact without harming it. They provide the model's soft traction that enables its performance without harming or damaging the turf and grass field. This allows the tire to perform at its best capability and it makes it perfect for lawn mower applications.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.
