Kenda K513. FEATURES AND BENEFITS: Improved controllability; Year-round traction; Longer-lasting tread life; . OVERVIEW: The Kenda K513 is an all season tire manufactured for lawn mowers and garden tractors.The ideal tread pattern and the durable rubber compound enhance the tires performance on various terrain surfaces. They work together to increase the tires forward motion on grass and turf surfaces. At the same time, this wide footprint and the special tread elements maintain constant surface contact during the performance. It upgrades the tires steering response time and accuracy to the drivers instructions, while the structure is secured against driving pressure. As a result, these elements guarantee a safe driving experience, while the driver has full control over the vehicle.The model ensures its longer-lasting tread life. The ideal tread design evenly spreads out the driving pressure along the tread area, while the special silica compound slows the treadwear rate down. Their combination actively prevents irregular and premature wear formations. This even and reduced wear boosts the tires service life and usability.The Kenda K513 enhances its all weather traction. The ideal tread pattern, with the optimized elements, firmly grips the surface with extra biting edges and maintains constant surface contact at all times. On the other hand, the all season compound keeps the rubber flexible in changing temperatures, from warm summer to cold winter situations. This combination effectively increases the tires traction in dry, wet, and winter conditions.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.
