About the Federal SS595

Performance Grip Built for Enthusiast Driving

Best forThe Federal SS595 is best suited for coupe, sports car, and tuner vehicle owners who want ultra-high-performance handling with all-season, M+S-rated capability.

The Federal SS595 (Super Steel 595) is an ultra-high-performance all-season tire built for coupes, sports cars, and tuner vehicles. It delivers confident high-speed stability and year-round traction in dry, wet, and light winter conditions. Carrying an M+S rating, it suits enthusiast drivers who demand sharp handling without sacrificing everyday usability.

The SS595 uses a directional tread pattern with unidirectional grooves engineered to maintain stability and grip at elevated speeds. A steel tie cord and reinforced sidewalls help the tire hold its shape across varying temperatures, while stiffened center and shoulder blocks work together to sharpen grip and resist uneven wear. An optimized tread pitch sequence keeps cabin noise in check.

Questions about this tire

What does 275/40ZR18 99W mean?

275 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 99 is the load index (1,709 lbs per tire), and W is the speed rating (up to 168 mph).

Is the Federal SS595 a true all-season tire, and what conditions can it handle?

Yes, the SS595 is an all-season UHP tire rated M+S, meaning it is designed for use in dry, wet, and light winter conditions including occasional snow and mud. However, it does not carry the Three-Peak Mountain Snowflake certification, so drivers in regions with heavy snowfall or severe winter conditions should consider a dedicated winter tire for those months.

Does the Federal SS595 come with a mileage warranty?

The SS595 does not include a manufacturer mileage warranty. Longevity will depend on driving habits, vehicle alignment, and proper tire maintenance such as regular rotations and inflation checks.

Do Federal SS595 tires tend to run wide compared to their labeled size?

Yes, the SS595 is known to run on the wider side relative to its stated size. This is intentional for a UHP fitment — a broader contact patch puts more rubber on the road, which supports grip, quicker acceleration, and shorter stopping distances.

Is the Federal SS595 a good choice for a daily-driven sports car or tuner build?

It is a solid option for enthusiast drivers who want UHP-level handling and all-season flexibility at an accessible price point. The reinforced construction and directional tread deliver responsive performance, making it a practical fit for coupes and tuner vehicles used year-round in moderate climates.

What vehicles and rim sizes does the Federal SS595 fit?

The SS595 is designed for passenger cars — specifically coupes, sports cars, and tuning vehicles. TFS Wheels currently stocks this model in sizes fitting 17-inch and 18-inch wheels; check the size selector for the specific fitments available for your vehicle.

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.
