The RubberMaster S366K is an all season tire manufactured for lawn mowers and garden tractors. The ideal tread pattern and the all season compound enhance the tire’s dry, wet, and winter-weather grip. As a result, the optimized tread design closely follows the turf surface at all times, while the all season compound keeps the rubber flexible in changing temperatures. The well-designed tread pattern’s continuous surface contact improves its steering responsiveness and driving stability. The tire’s soft traction and the ideal tread pattern work together, in order to upgrade its turf-friendly drive. The RubberMaster S366K offers great performance on various surfaces, thanks to its ideal tread pattern and rubber compound.

FEATURES

The ideal tread design and the all season compound work together to upgrade the dry, wet, and winter-weather performance. The durable compound elements and the detailed siping placement increase the tire’s surface traction to ensure a safe year-round drive. The compound elements optimize the rubber’s flexibility throughout the year, in various temperatures. The tread design’s blocky design effectively grips the driving surface, which boosts the model's traction.

The tread pattern upgrades driving stability and steering responsiveness, with the tire’s constant surface contact. This boosts the steering response time and accuracy to the driver’s commands. Additionally, the tire’s structure is stabilized against the driving pressure affecting it. The symmetric tread’s shoulder pattern provides additional biting edges that firmly grip the turf surface to boost the cornering ability and power.

The model’s excellent performance does not damage the grass field due to its optimized design and soft traction. This makes the tire perfect for lawn applications.

Attention! Due to the size of the tires, Packages might be SEPARATED in the courier facility and not be DELIVERED on the SAME DAY, even though we do ship them together. Tracking information can be checked by logging on to the courier website with the master tracking number you will receive via email. For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control.

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.
