ST918

Sumitomo ST918 is a commercial replacement tire built for 19.5-inch work-truck service where load support and dependable uptime matter. The Sumitomo ST918 tires are available in 225/70-19.5, giving Big Brand Tire & Service shoppers a catalog-backed LT fitment with Load Range G and speed rating M.

This single-size fitment is a strong match for medium-duty trucks, chassis cabs, and other vocational vehicles that need an exact replacement for route work, delivery service, and regional hauling. Sumitomo’s commercial design includes a computer-designed tread pattern, application-specific tread compound, radical shoulder ribs, curbing ribs, a four steel belt package, and deep original tread depth to support traction, casing durability, and stable wear under load.

If you’re confirming the right 19.5-inch replacement, Big Brand Tire & Service can help you match the size and get back on the road. Start with Shop Tires or book a Schedule Appointment for fitment help and installation.
