About the Summit Ultramax AS

Everyday Confidence, Mile After Mile

Best forDaily commuters and passenger car owners seeking reliable all-season performance, a quiet ride, and solid wet-weather capability across a wide range of rim sizes.

The Summit Ultramax AS is a standard all-season tire built for passenger cars, including coupes and sedans. It delivers dependable grip across dry, wet, and light winter conditions, backed by a 50,000-mile tread life warranty. Covering 15- to 18-inch rim sizes, it targets drivers who want reliable everyday performance without sacrificing comfort or fuel economy.

A symmetrical tread pattern uses variable pitch sequencing to minimize road noise and smooth out vibrations. The silica-enriched compound improves wet-road grip while helping reduce rolling resistance for better fuel efficiency. Four wide circumferential grooves evacuate water quickly to lower hydroplaning risk, a reinforced high-turnup sidewall adds structural strength and load capacity, and a jointless bead cover keeps the tire's shape stable for a consistent, comfortable ride.

Questions about this tire

What does 225/50R17 94V mean?

225 is the tread width in millimeters, 50 means the sidewall is 50% of that width, and R17 is the 17-inch rim it mounts on. 94 is the load index (1,477 lbs per tire), and V is the speed rating (up to 149 mph).

Can the Ultramax AS handle all four seasons reliably?

The Ultramax AS is engineered for dependable traction in dry, wet, and light winter conditions. It is not Three-Peak Mountain Snowflake certified, so it is not intended for heavy snow or severe winter driving — a dedicated winter tire is a better choice for those conditions.

What does the 50,000-mile warranty cover?

Summit backs the Ultramax AS with a 50,000-mile limited manufacturer tread life warranty. This is a model-level warranty; consult the warranty documentation for specific terms, conditions, and any exclusions.

How does the Ultramax AS perform in wet weather?

The silica-based compound enhances grip on wet pavement, and four wide circumferential grooves work to evacuate water from the contact patch quickly. Together, these features help reduce the risk of hydroplaning in rainy conditions.

Will this tire help with fuel economy?

The silica compound is formulated to lower rolling resistance compared to conventional rubber, which can contribute to modest fuel savings over time. Real-world gains will vary depending on vehicle, load, speed, and driving habits.

Where is the Summit Ultramax AS manufactured?

The Ultramax AS is produced overseas, either in China or Thailand, depending on the production run. Summit is an American brand founded in 1974, but manufacturing takes place at these international facilities.

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.
