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.
Let customers speak for us
These wheels make my Kia Stinger pop!
Everything was A+: fast shipping, great communication, a seamless transaction.
People said these wheels wot fit they were wrong People said these wheel would rub they were wrong People said these wheels would not look good on the car they were wrong! So now I don't talk to those people anymore because they were wrong!! Lol
Thanks you guys for a great deal!
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.
I had got some rims like these ones before. So I decided to buy more. They’re very awesome looking the color. The depth of the rim is awesome. Looks great on my car.
Got these for my subaru sambar, excellent for my needs and low cost
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 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 absolutely love my 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
Had a little back and forth on how many were actually available, but communication got us through that. Product is spot on what was advertised though. One piece of advice would be to look carefully at the color of the trim on your car if you are getting gunmetal. I love the gunmetal finish, but the silver (shiny’er) one would have been an even better match. No complaints on our S90L though.
Love how they look with 30s
Amazing quality. Fast shipping. Best price online. I can't see any reason for wanting to order from anyone else.
Wonderful throughout. Would recommend to anyone.
