The Castle Rock ST Radial ST226 is a highway terrain, all season tire made for trailers. This model should not be mounted on light trucks.

The tire promotes great all weather traction, with the symmetric tread design and the all season compound. The tread pattern, with the optimal groove and tread block placement, upgrades grip on the road surface in dry, wet, and winter weather conditions. The stronger compound elements allow the tire to optimize rubber flexibility in versatile temperatures, even in colder conditions. The circumferential grooves prevent hydroplaning as they disperse water and slush from the footprint, further boosting the wet weather driving experience.

The model also guarantees the towing performance. The reinforced internal structure, with the full-nylon cord construction, keeps the ideal tire shape under load and driving pressure. This greatly improves the tire’s load-carrying capability, boosting the overall heavy-duty performance. The strengthened construction also protects the tire from external damage. It avoids punctures, impact damage, and cuts from harming the casing, preventing them from shortening the service life.

The Castle Rock ST Radial ST226 boosts handling as well. The tread design’s continuous center rib ensures surface contact throughout the drive, which improves steering responsiveness and driving stability. This results in a quick and precise in its response to the driver’s commands, while the structure is secured against driving pressure. The tread’s shoulder block placement upgrades the cornering and maneuvering ability, optimizing the performing safety levels.
