Sumitomo has a big reputation when it comes to commercial tires. Their models always make jobs easier and safer, allowing for new opportunities. As an example, the ST720 features both great stability and high mileage in mixed service applications. It is engineered for all positions of dump and crane trucks that choose this model's sizes. With such technology, construction work has never been better.
Primarily, the ST720 makes perfect use of unique wide shoulder ribs with notching that offer high stability in turns or at speeds up to 68 mph. Next, an advanced tread compound resists cutting and chipping, thus promoting long rubber life. A unique zigzag groove pattern as well as the lug shape offer supreme traction through any environment. Along with that, a low risk of skidding and confident braking ability on wet roads is guaranteed. A wide patch area ensures the right distribution of weight on the surface, thus being efficient with loads up to 12,300 lbs per tire. Durable sidewalls ensure strong lateral grip and responsive steering. The modern internal construction of this model prevents damage from punctures, therefore allowing for more retread cycles. Moreover, Sumitomo uses cutting edge technology to optimize fuel usage and minimize rolling resistance.
Above that, the model comes with a 6 year or 2 recap casing warranty. It comes on the US market in a few major sizes, these being: 385/65 R22.5, 425/65 R22.5, and 445/65 R22.5.
