Serious community work requires a variety of well design tires from the market, and Sumitomo knows how to handle these requests just fine. For such situations, they released the new ST518 which is specifically designed for mixed service vehicles like dump trucks and ready-mixed trucks. This all position model excels in this type of commercial usage and fits perfectly on every axle of the vehicle.
Firstly, Sumitomo equipped this model with an advanced specific rubber compound that effectively neglects to cut and chip. A 21/32" deep tread design decelerates uneven wear for long usage of the product. Moreover, a wide patch area evenly distributes loads up to 7,390 lbs along the tire surface, creating balance and durability. The ST518 benefits from closed shoulders with optimized notching that boosts traction on all kind of roads. Multiple rows of zigzag shaped grooves are optimally placed to expel water and provide safe and stable rides during rain.
Furthermore, smartly positioned stone ejectors at the bottom combat the retention of mud and sand for high casing integrity and protection. The innovative siping design on the lugs offers a confident road grip, leading to successful commercial services. On the inside, we can find four belts of steel that deny punctures, promoting a stable and long tire life. A modern sidewall design combats lateral forces for responsive handling at speeds up to 68 mph.
Above all, Sumitomo caresses their customers with a 6 year or 2 recap casing warranty. The ST518 is available on the US market in some high-demand sizes: 10.00R20, 11.00R20, and 12R22.5.
