We all know that mixed service applications need tough traction and durable tires to be successful. We also know that trusty manufacturers like Sumitomo provide just the right models for that. For example, their ST901 is a strong drive tire that helps vehicles engaged in logging and construction complete their jobs. This model features advanced technology that excels in such commercial branches.
Firstly, this model is denveloped with a modern compound that resists high scrub environments. A unique open shoulder design with grooves provides extra traction on slippery surfaces. With an optimized placement of sipes on the lugs, this tire offers superior road grip at speeds up to 68 mph, thus preventing skidding. Large grooves are present to decrease water buildup and increase safety during bad weather. Sumitomo optimally distributed stone ejectors that shield the casing from damage and prevent stone retention. Big lugs spread along the tread area deliver strong traction and casing integrity with loads up to 7,160 lbs per wheel, therefore increasing mileage.
Moreover, a sturdy layer of rubber under the tread defends the interior construction for numerous retread cycles. Below that, four belts of steel protect the tube from punctures, while also increasing vehicle stability. Stiff curbing ribs on the sides prevent sidewall scraping and also enhance control in turns. Besides, a 32/32" tread depth neglects damage from cuts and chips so drivers can benefit from years of tire life. Wide spacing between the lugs allows the placement of chains in situations when we need more traction. Furthermore, rust inhibitor compounds cover the belts and body ply components that make the ST901 a durable tire. Finally, Sumitomo backs its buyers with a 6-year or 2-recap casing warranty. This model can be found on the US market in 2 popular sizes: 11R22.5 and 11R24.5.
