About the RTX Steel

Step up to an 18-inch fitment and the RTX ST takes on a more assertive character without abandoning its understated roots. The 18x8 in Black is the wheel for the enthusiast who appreciates a slightly wider stance and a larger contact patch — someone who drives a BMW 3 Series, 5 Series, or Land Rover Discovery Sport and wants a finish that complements the car rather than competing with it.

The 5x120 bolt pattern is the signature of the BMW lineup, and the RTX ST is engineered specifically for that platform. The 67.1mm centerbore aligns with common OEM hub bore dimensions across BMW models, supporting a hub-centric fit that eliminates harmonic vibration at highway speeds. The +38 offset positions the wheel face flush with the fender line, giving the car a planted, factory-plus look that feels intentional rather than modified.

At 18x8, this wheel carries a load rating of 630 kg per corner, providing reliable structural support for heavier European platforms. The Black finish is clean and durable, pairing naturally with the chrome trim and body lines that define the modern BMW aesthetic. Whether this is going on a daily-driven 3 Series or a weekend-ready 5 Series, the RTX ST makes a composed, confident statement.

Why TFS Wheels

Authorized Dealer — 100% Brand New Wheels

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 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 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.

They look way better in person! These were for a dual spare setup and they actually look great and would buy a full set if I was in the market for a full set. The price was great as well.

Great looking wheel!

Put these on my 2013 Lincoln MKZ in machined grey. Got tired of the factory 19’s bending every time we hit a pothole. Went with an 18 on these and saved 7 pounds per wheel. They look great and the ride is better too.

Great to do business with

Great company to work with in purchasing your new wheels and related products. Initially, I was going to give only 4 stars due to the fact that the wheels I really wanted were actually on backorder despite being advertised as “in stock” on their website and the need to buy the last full set for the advertised price (which further implied the wheels were available). Initially blamed wheel manufacturer for not updating their supply which I believe is true but it’s also TFSWheels’ responsibility to maintain their own site. Nonetheless, TFSWheels was quick to respond and offered to refund my purchase. I decided to pick another wheel that they did have in stock. Throughout the exchange, TFSWheels (Jeremiah) was very responsive to all my questions or concerns. They even made sure if I knew my wheels would fit since I have an older Land Cruiser. Once selected, they stood by their pricing for the new selection and service was outstanding. Wheels arrived in great condition and now I am even happier after seeing my new selection. So 5 stars is the right rating and I would buy again from them!

Love the style. Looks stock and classy, not too much. Clients love the exposed red brake calipers and clean look when pulling up.

Excellent service! Recommend.

Excellent service provided by Jeremiah. Great communication, went the extra mile trying to find a perfect fit for my car. The wheels were beautiful, great quality, fast shipping, but unfortunately not a fit for my vehicle. Would recommend TFS to anyone who needs new wheels!

I was very happy with purchase. Did have a bump with lugs. Jerrimah and worked through it. Just verify some Lexus use lug bolts instead of lug nuts. Very happy with end results
