Heavy-duty jobs such as construction services need to benefit from high quality equipment, and here Sumitomo intervenes. With models like the ST520, mixed services come to know new heights of performance. This tire is specifically optimized for the dump and ready mixed trucks so their job can go as smoothly as possible. It is an all position model, so it will excel in every location of the axle.
The ST520 stands out because it has 40% more tread depth than most tires. Due to the premium S-Tech Design, it guarantees high performance and fuel efficiency. Firstly, its praised tread depth of 24/32" enhances traction and resistance on high scrub surfaces. A modern tread composition offers high protection from external damage. This model features a stiff semi-open shoulder design with grooves that minimize heat buildup and boost road grip. A wider patch area ensures an even distribution of loads up to 12,300 lbs per wheel. It takes advantage of a unique lug pattern that delivers premium traction and braking in off road usage.
The ST520 benefits from zigzag shaped grooves that boost water evacuation and decrease the risk of aquaplaning. Stone ejectors are present in these channels to make sure no mud or sand remains stuck in the tread. Hard sidewalls increase lateral grip and lower the rolling resistance, therefore allowing for safe commercial applications. Moreover, the internal build of this model offers great resistance to large spikes and punctures, thus promoting tire life. Four steel belts under the patch enhance vehicle stability at even 68 mph and allow for numerous retread cycles.
Finally, this tire is backed by a 6 year or 2 recap casing warranty for peace of mind. Sumitomo released the model on the US market in some popular sizes: 385/65 R22.5, 425/65 R22.5, and 445/65R22.5.
