Sumitomo ST918

SUMITOMO ST918 225/70R19.5, 245/70R19.5 DRIVE AXLE TIRE

The Sumitomo ST918 225/70R19.5 and 245/70R19.5 are highway-terrain, all-season commercial truck tires engineered for dependable drive-axle performance. First of all, these sizes are ideal for medium-duty trucks operating in regional and on-highway applications, where durability and traction are essential.

Moreover, the reinforced steel belt construction maintains the tire’s optimal shape under heavy loads and continuous driving pressure. As a result, the casing resists deformation, allowing the tire to safely carry higher payloads while preserving consistent road contact. In addition, this structural stability improves handling control and overall driving safety.

Furthermore, the ribbed tread design, combined with optimized siping and wide circumferential grooves, enhances year-round traction. In other words, the tread creates additional biting edges for reliable grip in dry, wet, and light winter conditions. Meanwhile, the all-season compound remains flexible across temperature changes, ensuring consistent performance. At the same time, the grooves efficiently evacuate water and slush, significantly reducing hydroplaning risk.

Finally, the Sumitomo ST918 in 225/70R19.5 and 245/70R19.5 is built for long tread life. Even pressure distribution across the footprint minimizes irregular wear, which ultimately delivers extended service life and lower operating costs for commercial fleets.
