About the Kumho Ecsta AST

Year-Round Performance Without the Compromise

Best forDrivers of performance sedans and coupes seeking confident all-season grip and long tread life in mixed dry, wet, and light-snow conditions.

The Kumho Ecsta AST KU25 is an ultra-high-performance all-season tire built for drivers of performance sedans and coupes who refuse to compromise grip for year-round usability. It delivers confident handling on dry pavement, strong wet-weather traction, and adequate light-snow capability — all backed by a 60,000-mile treadwear warranty that's rare in the UHP segment.

A directional tread pattern channels water away through wide circumferential grooves and angled blocks lined with dense sipes, reducing hydroplaning risk and improving wet grip. A high-carbon-black compound boosts durability and traction year-round, while shoulder blocks with sharp leading edges resist heel-to-toe wear. An ultra-hard bead filler and reinforced sidewall with rim protector add high-speed stability and curb-impact resistance.

Questions about this tire

Is the Ecsta AST KU25 suitable for performance cars?

Yes. The KU25 is specifically engineered for performance sedans and coupes, prioritizing responsive handling and high-speed durability alongside all-season traction. Its ultra-hard bead filler and reinforced sidewall construction support the demands of spirited driving.

How does the KU25 perform in wet conditions?

The directional tread design uses wide circumferential grooves, angled tread blocks, and dense sipes to evacuate water and maintain contact with the road surface. This combination helps reduce hydroplaning and keeps wet-weather braking and cornering predictable.

Can the Ecsta AST KU25 handle winter driving?

The KU25 manages light snow and cold-weather commuting reasonably well for an all-season tire. However, it is not Three-Peak Mountain Snowflake certified, so drivers who regularly face heavy snow, ice, or severe winter conditions should consider a dedicated winter tire for maximum safety.

What kind of treadwear warranty does the KU25 carry?

Kumho backs the Ecsta AST KU25 with a 60,000-mile treadwear warranty — a notably strong coverage figure for a UHP all-season tire. The shoulder block design and high-carbon-black compound both contribute to achieving that longevity.

Does the directional tread pattern affect how I rotate these tires?

Yes. Because the KU25 uses a directional tread, rotations must be done front-to-back on the same side of the vehicle — side-to-side swaps are not permitted without dismounting and remounting the tires. Plan for this when scheduling routine maintenance.

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.
