Forged Wheels 21" Smitherim – For Motorsport and Everyday Use.

Forged wheels Smitherim are a perfect combination of durability, lightness, and precision craftsmanship. They are made from high-quality aluminum alloy – 6061-T6. This material is characterized by high hardness, strength, corrosion, and oxidation resistance, and excellent welding properties. It is used in industries such as aerospace, military, shipbuilding, and construction. Thanks to advanced forging technology, these wheels feature exceptional durability and excellent mechanical properties, making them the ideal choice for the most demanding drivers – whether in sports, luxury, or utility vehicles.

Production Process of Forged Wheels.

Thanks to an advanced production process, forged wheels are extremely lightweight, durable, and resistant to dynamic loads. To achieve the highest standards, each wheel Smitherim undergoes complex production processes consisting of several stages:
1. Raw aluminum material is first heated to a high temperature to facilitate plastic forming.
2. The forging process follows – under enormous pressure, the material is formed into the shape of a wheel using a hydraulic press with high force, giving it remarkable density and strength. This process ensures an ideal molecular structure, resulting in exceptional lightness and durability of the wheel.
3. The wheel goes through heat treatment processes to further enhance its mechanical properties.
4. Final stages include precise machining, finishing, and painting, giving the wheel its final appearance and specifications.

Forged wheels Smitherim are an investment in quality, durability, and exceptional aesthetics, satisfying every automotive enthusiast. If budget is not a constraint, forged aluminum wheels are an excellent choice.

Testing and research ensure high-quality alloy wheels

The production process of Smitherim wheels ends with a series of tests, during which numerous tests are conducted. Only alloy wheels that have passed all the following tests are introduced to the market:
✅ tensile test
✅ radial and dynamic balancing test - with deviations up to 0,6 mm (PIMOT recommendations allow 0.8 mm)
✅ verification of the center hole - permissible tolerance up to 0,3 mm
✅ corrosion resistance test
✅ structural integrity and lack of micro-cracks are diagnosed using an X-ray machine
✅ leak test
✅ paint coating evaluation
✅ load-bearing capacity test
✅ bending resistance test under twisting
✅ rolling resistance test
✅ impact test
✅ variable torque test

Alloy wheels manufactured in certified factories.

The factories where GT Fusion alloy wheels are manufactured have obtained certifications: American Smithers, TUV NORD (ISO9001, IATF16949), ISO14001, ISO45001, ISO50001, American DOT-T, Japanese VIA, Brazilian INMETRO. The specifications define the quality system requirements for products in the fields of design, production development, installation, and servicing in the automotive industry. Most production processes are fully automated. Advanced forging technology combined with international automotive industry standards enables the production of reliable products – high-quality GT Fusion alloy wheels.

Fitment Guarantee

We continuously expand our offer and update the database so you can easily find the right wheels for your car model. If you find your model in the "Fitment Guarantee" list, you can be sure that you are buying the correct wheels. However, if you have any doubts or questions, feel free to contact our Customer Service Department, where you will get answers to most questions.

We select alloy wheels according to the manufacturer's catalog parameters. For some car models or wheels, it may be necessary to use spacers, and special bolts/nuts, which you can easily find in our store in the "Accessories" section.

The risk of error is minimal, but before installation, check whether the wheels fit your car, have no deviations, do not rub against suspension parts, and do not protrude beyond the fender. It is important to verify the goods BEFORE fitting the tires onto the wheels. Fitting tires is unnecessary and will prevent the correct diagnosis of the product. Alloy wheels should be fitted on both axles of the vehicle. However, if you visit a service/shop, inform the tire fitter to perform the above tasks first.

Accessories in one of the four boxes

Upon receiving your order, check if the package contains all the products you purchased. Caps and other accessories may be attached to the bottom of the box or be in one of the four boxes.
