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.
