About the Sumitomo ST918

Built Tough for Every Urban Mile

Best forCommercial trucks on drive axles navigating demanding urban and metropolitan routes where durability and traction are essential.

The Sumitomo ST918 is a commercial drive-axle tire built for trucks operating in demanding urban and metropolitan environments. It prioritizes durability, traction, and sidewall protection to handle the stop-and-go stress of city routes and rough road surfaces. Fleets and owner-operators looking for a dependable, work-ready tire for 19.5-inch rims will find the ST918 a practical choice.

The ST918 uses a symmetrical tread pattern that has been computer-tuned to reduce road noise and smooth out the ride. A multi-phase center tread section improves traction and braking performance, while grooves and microgrooves channel water away for better wet-weather grip. Reinforced sidewall protection ribs defend against curb and debris damage, and steel-belt construction supports long-term wear.

Questions about this tire

What axle position is the ST918 designed for?

The ST918 is specifically engineered for drive-axle fitment on commercial trucks. Its tread design and construction prioritize the traction and braking demands that drive positions require, particularly in urban and metro environments.

How does the ST918 handle wet road conditions?

The tire incorporates both grooves and microgrooves to help evacuate water from the contact patch and maintain grip on wet surfaces. While these features improve wet-weather performance, drivers should always adjust speed and following distance in heavy rain or standing water.

Is the ST918 suitable for winter or snow conditions?

The ST918 does not carry the Three-Peak Mountain Snowflake certification, meaning it is not rated for severe snow service. Fleets operating in regions with significant winter weather should consider a dedicated winter or 3PMSF-certified commercial tire for those conditions.

What kind of warranty does the ST918 carry?

The ST918 is covered under Sumitomo's manufacturer warranty. There is no additional mileage warranty associated with this model, so buyers should confirm specific warranty terms directly with Sumitomo or an authorized dealer at the time of purchase.

Will the sidewalls hold up to the wear and tear of city driving?

Yes, the ST918 includes reinforced sidewall protection ribs designed to guard against the scrapes, curb contact, and debris impacts common in urban commercial work. This feature is intended to extend the overall service life of the tire in those demanding conditions.

Buying from TFS Wheels

Shipping, returns & guarantees

Authorized Dealer — 100% Brand New Wheels & Tires

TFS Wheels is an authorized dealer for every brand we carry. Every wheel and tire we ship is brand new, unused, and packaged in its original manufacturer's box. We never sell refurbished, demo, or return-stock product. All manufacturer warranties apply and our warehouse is staffed by people who only handle wheels and tires — no in-transit damage, no test-fits, no surprises.

Free Shipping (Lower 48)

Free shipping on every order — wheels, tires, and accessories — to the contiguous United States. No minimum order, no hidden fees.

Standard delivery is 4–7 business days; expedited is 1–4 business days. Orders placed before 1:00 PM ET typically ship the same day. We do not ship internationally or to PO boxes.

Fitment Guarantee

If a wheel or tire marked "Direct Fit" or "Aftermarket Fit" for your vehicle arrives and does not fit as expected, we cover both the restocking fee and return shipping. The same applies if the bolt pattern does not match — provided your vehicle information was submitted at checkout.

To qualify for the guarantee, enter your year, make, model, and submodel before placing the order.

Manufacturer's Warranty

Every wheel and tire is covered by the full manufacturer's warranty against defects in materials and workmanship. Coverage terms vary by brand — most cover structural integrity for the life of the wheel and finish for 1 to 2 years from purchase. If you ever have a warranty question, contact us first; we work directly with the manufacturer on your behalf so you don't have to.

Accessories Included with Your Order

When you submit your vehicle information at checkout, the right lug nuts and (if needed) hub-centric rings are automatically added to your cart in the correct sizes — no guessing, no separate ordering.

TPMS sensors are also available in the cart. We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed. This typically saves customers the dealer or installer's programming fees, which often run several dozen dollars per wheel.

Returns

Returns are accepted within 30 days of purchase on items in new, unused condition. A 25% restocking fee applies to general (change-of-mind) returns, and the buyer covers return shipping.

The restocking fee and return shipping are waived for incorrect items, transit damage, or fitment issues when vehicle information was provided at checkout. Single wheels, single tires, mounted items, special orders, and accessories (lug nuts, locks, hub-centric rings, TPMS sensors, installation kits) are final sale.
