BKT TR-315. FEATURES AND BENEFITS: Enhanced traction; Upgraded durability; Self-cleaning tread design; . OVERVIEW: The BKT TR-315 is an all season tire manufactured for garden and lawn tractors.The tire offers an enhanced traction in different weather and on various terrain surfaces. The better traction upgrades the tire's controllability as it keeps its traction and terrain grip to ensure its safer forward traction. The directional lug placement enables the tire's performance even on terrains that require high flotation to not get stuck in the soft soil or mud. The tread's improved traction, in this manner, guarantees a secure performance throughout the tire's lifetime.The strengthened internal structure increases the driving durability. The construction does not allow the tire to deform under the driving and load pressure affecting the tire. The maintained ideal tire shape increases the tire's performing capability on various terrain surfaces. The better controllability of the tire ensures the driver's complete control over the vehicle to improve its driving safety.The TR-315 features a self-cleaning tread design. The directional lug placement and the high void ratio improve the tire's contact with the road and terrain surface. This prevents mud and rocks from getting stuck between the tread elements and blocking the tire's contact with the surface. The self-cleaning nature of the tread also actively avoids stone retention from harming the casing and shortening the tire's service life.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.
