The Westlake ST100 is a tire designed for trailers, specifically highway terrains. However, it is important to note that this tire is not suitable for use on light trucks due to its construction limitations. The tire is reinforced with a steel belt and a nylon cap overlay, which helps maintain its shape and enhance its load capacity. With this structure, the tire is able to carry heavy loads without deformation or performance issues. One of the key features of the Westlake ST100 is its all weather traction, which is improved by the tire's compound. This not only enhances its grip on the road but also reduces the rolling resistance. By reducing the rolling resistance, the tire decreases the fuel consumption and CO2 emissions of the towing vehicle, making it more fuel efficient and environmentally friendly. In addition, this tire offers an extended tread life. The steel belt construction provides protection against external damage, while the durable compound and symmetrical ribbed pattern contribute to slower tread wear. As a result, the Westlake ST100 ensures a longer period of usability. Please note that this tire is only suitable for mounting on trailers and not on light trucks.
