Deestone D622 A78-13 ST Tires
The Deestone D622 A78-13 ST is a touring, all season tire made for trailers. The model should not be mounted on light trucks.
The all season traction is guaranteed at all times. The stronger compound and the detailed tread elements improve the dry, wet, and winter weather grip on the road surface. The tread elements improve the versatile temperature performance, boosting the summer and winter weather performing ability. The siping pattern generates traction with extra biting edges, upgrading the surface performance. The zigzag circumferential grooves prevent hydroplaning as they disperse water and slush from the footprint in wet conditions.
The flat symmetric footprint and the ideal tread design ensure surface contact with the center rib. This greatly improves the steering responsiveness and the driving stability. As a result, the tire is quicker and more precise in its response to the towing vehicle’s commands, while the structure is secured against the driving pressure affecting the tire. The stronger structure allows the tire to improve the load capacity. As the tire does not deform under the load and the driving pressure. This ensures an excellent towing experience.
The Deestone D622 A78-13 ST boosts the strengthened construction. The tire’s bias-ply structure maintains the ideal tire shape as it is reinforced with the nylon casing. As the tire shape keeps the ideal tire shape under the load and driving pressure. In this manner, the tire is able to securely carry and withstand heavy loads with ease. This significantly improves the overall load capacity.
This is a bias ply or diagonal tire. Due to the tire’s internal construction and size, it is possible that the tire will look deformed. Smaller diagonal 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.

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.
