Sumitomo ST909 is an advanced drive position tire made optimized for regional applications. This tire features a wider tread face with wide solid shoulders that help to evenly redistribute the load pressure for long and even wear. The advanced Y-Shaped groove design has embedded stone ejectors that help to minimize stone drilling and protect the casing, promoting longer tire life. ST909’s deep shoulder blocks help to increase traction in challenging weather conditions, while the Four Steel Belt Package resists punctures, increases stability of the fleet, and contributes to more retread cycles.
