NOTE: THIS PRODUCT REQUIRES ADAPTERS, SOLD SEPARATELY
The STE M Tire Siper is your ultimate solution for tire siping, allowing operators to effortlessly sipe both non mounted and mounted tires using the same machine. For non mounted tires, our expandable rims accommodate sizes ranging from 13″ to 24.5″, easily fitting over the standard expanding hub of the STE M. When working with mounted tires, the expandable hub conveniently swings out of the way, enabling the wheel to be fitted with the necessary adapter and rolled into the machine for siping. Regardless of the application, a tire can be mounted, siped, and dismounted in as little as 3 to 4 minutes, making this process incredibly efficient.
Any type of tire can be siped whether new, re cap, or used as long as it retains at least 5/32” of tread. Drivers everywhere are recognizing the benefits of tire siping due to its proven ability to significantly enhance overall tire performance, providing a safer and more efficient driving experience.

We ship to the 48 contiguous United States and Washington, DC. Products ship from manufacturing partners and fulfillment centers across the United States. Shipping method and cost depend on the product, selected delivery option, and destination.
For standard in-stock parcel and freight orders, processing normally takes 2–5 business days, followed by an estimated 5–10 business days in transit. Typical total delivery is approximately 7–15 business days. Business days are Monday–Friday, excluding U.S. federal holidays. Orders placed outside business hours begin processing the next business day.
Any known longer product lead time is disclosed before purchase. Dates are estimates. If we cannot meet the stated shipment timeframe, we will notify you and explain your delay-consent and cancellation/refund options under our Shipping Policy.
Where the selected shipping option expressly includes delivery, no additional shipping charge is added at checkout. Other products use disclosed flat, destination-zone, or calculated shipping rates. The applicable charge is shown before payment. Orders requiring a freight quote must have that quote accepted before purchase. Mixed orders may include more than one shipping charge.
Smaller products may ship by parcel carrier. Tracking is provided when available after shipment. Separate packages may arrive on different days. Parcel shipping does not include installation or assembly.
Heavy, crated, or palletized equipment may ship by LTL or another freight carrier. Delivery is to a safe, truck-accessible curbside or receiving point. Inside placement, installation, unpacking, and assembly are not included unless expressly stated.
Where suitable liftgate service is included for the product, the carrier lowers the shipment to ground level. Products too large or heavy for liftgate service require customer-provided unloading equipment, such as a suitably rated forklift or compatible loading dock. The applicable requirement must be identified for the product before purchase. A pallet jack alone cannot lower freight from a truck.
We do not charge separate residential, commercial-address, or eligible liftgate service fees. Reasonable documented costs caused by a missed agreed appointment, inaccurate delivery information, or failure to provide previously disclosed unloading arrangements may apply under the Shipping Policy. Seller or carrier errors are not customer-caused delivery failures.
Where offered, pickup depends on stock at the selected partner facility and requires a confirmed appointment and our Pickup Authorization Pass. An order confirmation is not pickup authorization. Pickup does not include delivery to your address.
Read the full Shipping Policy or contact support@forgelinesupplyco.com with questions.
These generally include smaller parcel-shipped tools and accessories that do not require permanent installation. Eligible return requests must be submitted within 30 calendar days of delivery, or collection for warehouse pickup. Prior written RMA approval is required. Voluntary returns must meet our unused, uninstalled, complete, and original-packaging requirements.
These include oversized, palletized, crated, freight-shipped, or installed equipment, such as vehicle lifts, tire changers, wheel balancers, and large cabinet systems. Returns for buyer’s remorse, incorrect selection, or site incompatibility are generally not accepted unless expressly approved in writing. Submit a voluntary-return request within 30 calendar days of delivery or pickup; requesting approval does not guarantee acceptance. The product’s applicable category and any additional restrictions must be disclosed before purchase.
Approved voluntary returns are subject to a 28% restocking fee, customer-paid return shipping, and applicable documented outbound shipping deductions, including where the original delivery was included in the price. Freight return costs can be substantial. We provide an itemized estimate before you commit to an authorized return.
The restocking calculation excludes tax and separately charged shipping. If included outbound freight is deducted separately, it is first removed from the restocking calculation base. The same transport cost is not deducted twice. See the full policy for calculation details and condition-related deductions.
Voluntary-return restrictions do not automatically exclude verified fulfillment errors, transit damage, or qualifying defect claims. For approved returns of wrong items or goods confirmed damaged in transit, we arrange and cover required return transportation, with no restocking fee. Defect remedies and transport costs follow the applicable warranty and law.
Contact us before returning merchandise. Use only the return destination in your RMA; do not send goods to our mailing address unless that address is expressly authorized.
We normally inspect and notify you of our decision within 2–4 business days after receipt at the approved facility. Approved refunds are generally submitted to the original payment method within 5–10 business days after approval—normally 7–14 business days altogether, assuming approval follows inspection. Bank posting takes additional time. If further review is needed, we explain why and provide an expected decision date. Faster mandatory deadlines take precedence.
Warranty coverage, where offered, is provided by the applicable manufacturer and varies by brand and model. Coverage duration, parts, labor, transport costs, and exclusions are described in the applicable warranty documentation. A warranty claim is separate from a voluntary return. Contact us for assistance before returning equipment or undertaking repairs that may affect coverage. Manufacturer terms do not remove our obligations as seller or rights that cannot legally be excluded.

Known longer product lead times are disclosed before purchase. Dates are estimates; tracking is provided when available after shipment.
It depends on the product, destination, and selected delivery option. If the option expressly includes shipping, no additional shipping charge is added at checkout. Otherwise, applicable flat, zone-based, or calculated charges are shown before payment. Quote-required orders need an accepted quote before purchase. Pickup is separate from delivery.

Review the product’s unloading requirements before ordering. Inside placement and installation are not included unless expressly stated.
Only where offered for the selected product and partner location, subject to stock. You need a confirmed appointment and our Pickup Authorization Pass before traveling. An order confirmation alone does not authorize pickup.
Eligible Standard Product return requests must be submitted within 30 calendar days of delivery or pickup. Large / Freight Equipment is generally not returnable for buyer’s remorse unless expressly approved in writing. Approved non-defective returns are subject to a 28% restocking fee, customer-paid return shipping, and applicable documented outbound shipping deductions. Review the Returns & Warranty tab and Return & Refund Policy for eligibility and exceptions.
Inspect the shipment promptly. For freight, record visible damage or shortages on the delivery receipt before signing. Photograph the issue, keep packaging, and contact us within 48 hours of delivery for visible damage, or within 48 hours of discovery for concealed damage after prompt inspection. Report an incorrect item promptly.
A clean delivery receipt does not automatically invalidate a concealed-damage claim. If freight is severely damaged or clearly unusable, contact us before accepting when reasonably possible; refusal may be appropriate. For approved wrong-item or confirmed transit-damage returns, we arrange and cover required return transport. Rights that cannot legally be waived remain unaffected.
After an authorized return reaches the approved facility, inspection and the decision normally take 2–4 business days. Approved refunds are generally submitted within another 5–10 business days: normally 7–14 business days in total. Your bank may take additional time to post the credit. We explain any further review and provide an expected decision date. Different or shorter deadlines may apply to cancellations or refunds required by law.
The applicable manufacturer provides warranty coverage where offered. Terms vary by brand and model; review the relevant warranty documentation before purchase. Contact Forgeline support for help with a claim.
Contact us promptly so we can check its status. Voluntary cancellation eligibility depends on the disclosed terms and fulfillment stage.

Minor or visible damage — inspect before signing, photograph any damage, and describe it specifically on the Bill of Lading (e.g. “Crate damaged on left side”).
