Carlisle Sawtooth. FEATURES AND BENEFITS: Upgraded Handling Ability; Turf Friendly Traction; Improved Load Durability; . OVERVIEW: The Carlisle Sawtooth is an all season tire created for lawn mowers and other garden equipment.The tire's tread pattern consists of staggered ribs that form a completely flat footprint together. Throughout the performance, the tire stays stable and remains in contact with the terrain surface. With stability comes controllability, which is why this model is so easy to command. It responds to the driver's commands quickly and with great precision. With such smooth maneuvering, the whole driving experience becomes safer.The detailed tread pattern ensures outstanding turf friendly traction. Another benefit of the flat footprint is that it reduces the pressure applied to the driving surface. It promotes soft traction, which eases pressure off the terrain surface, preserving the ground by not loosening it up. For example, it can go over grass fields without causing any damage, ensuring safe performance.This model comes in a variety of ply ratings that enable the tire to withstand heavy loads without any difficulty. Its structure enhances its load capacity, allowing the tire to maintain its optimal shape. The tire can endure huge load and driving pressure without deforming, which helps it maintain its stability. The Sawtooth is an ideal choice for a safe heavy-duty driving experience.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.Due to the acquisition by Carlstar Tires, Carlisle tires are now manufactured under the Carlstar banner. For this reason, some Carlisle tires might come with the Carlstar brand name stamped on their sidewalls.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.
