Attention! Due to the size of the tires, Packages might be SEPARATED in the courier facility and not be DELIVERED on the SAME DAY, even though we do ship them together. Tracking information can be checked by logging on to the courier website with the master tracking number you will receive via email. For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control.
Features and Benefits:
The Sumitomo ST918 is a highway terrain, all season tire made for commercial vehicles. This model was created to be mounted on the vehicle's drive axle.
The stronger steel belt structure keeps the ideal tire shape under the load and driving pressure. The steel belts reinforce the model and prevent its deformation during its heavy-duty application. This enables the tire to securely carry and withstand larger loads. Additionally, this structure ensures the tire's better road contact, further optimizing the driving safety.
The tire helps to improve the year round traction. The ribbed footprint, with the optimal sipe and circumferential groove pattern, and the all season compound increase the tire's grip on the road surface throughout the year. In other words, the optimal tread elements provide additional biting edges in order to grip the road surface at all times. Stronger compound elements enhance the rubber flexibility in different temperatures. The circumferential grooves channel water and slush from the footprint, combating hydroplaning in the process.
The Sumitomo ST918 upgrades the tread life length. The specially placed siping detail stabilizes the footprint and ensures even pressure circulation across the tread area. This combats irregular and premature wear, preventing such wear formations from shortening the service life. In other words, the tire guarantees a lengthened usability.
Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
