You know the sound of a sweet set of aftermarket wheels when you hear them coming down the road. That deep hum when the spokes slice through the air. The glint of sunlight off that polished rim. We all love the look of a tricked-out rig rolling on a fresh set of alloys.
But have you ever wondered what these slick racing wheels are made from? What metals and alloys go into crafting these high-performance beauties? In this guide, we’ll break down the materials used to build the most popular wheel designs so you can understand exactly what gives these babies their edge.
Whether you’re looking to upgrade your whips or just want to appreciate the engineering behind premiere racing rims, you’re about to learn all about the science of wheel construction.
Materials used in XXR Wheels
XXR racing wheels are made from lightweight yet durable aluminum alloys that can handle high speeds and impacts. Their 5-spoke designs are crafted from 6061-T6 aluminum, an alloy prized for its strength, corrosion resistance, and weldability. For an even lighter build, XXR’s RT line uses 7075-T6 aluminum, an alloy containing zinc and copper that’s commonly used in aircraft parts. These high-performance materials allow the wheels to be both lightweight and able to handle the stresses of racing.
Cutting-edge coatings
To give their aluminum wheels a showroom shine and protect them from the elements, XXR uses advanced coatings like bright dips and powder coatings. Their bright dip coating chemically polishes and seals the aluminum surface, while their matte black powder coating provides a durable scratch-resistant finish with a satin sheen. For custom-colored or chrome-like wheels, XXR also offers custom powder coating services to match your vehicle’s paint or achieve a mirror-like chrome finish.
Rigorous testing
Before releasing any new wheel designs, XXR subjects each item to punishing stress tests to ensure they meet their high safety and performance standards. Their wheels are impact and fatigue tested for over 100,000 cycles and inspected for balance at speeds over 200 MPH. The testing procedures are so intensive that their failure rate during development is over 50%, and therefore they only release wheels that have proven their mettle. The result is a lineup of wheels that are as eye-catching as they are dependable.
Frequently asked questions about XXR racing wheels
When it comes to XXR wheels, this company doesn’t skimp on quality. Their alloy wheels are made from low-pressure cast aluminum alloy, the same stuff used in aircraft and race cars.
Aluminum alloys
The aluminum alloy used, typically A356, provides an ideal balance of strength and weight. Lighter than steel but pound-for-pound stronger, aluminum alloy can withstand the stresses of high-performance driving without adding excess weight that hurts acceleration and handling.
Forged construction
XXR wheels are manufactured using a multi-stage forging process. First, molten aluminum is poured into a mold to form a rough wheel shape. Then, intense heat and pressure are applied to strengthen the alloy and compress the molecules, a process known as flow-forging. Finally, the wheel is spun at high speeds as rollers shape and smooth the surface. This forging technique produces a wheel that’s denser, stiffer, and more durable than a basic cast wheel.
With the right materials and forging techniques, it can offer wheels that meet strict quality standards while still being affordable. XXR aluminum alloy wheels strike an ideal balance of performance, strength, weight, and cost, which is everything you need in a tuner wheel. Whether you drive a sports coupe, SUV, or full-size pickup truck, XXR has a set of durable, good-looking wheels to suit your needs without breaking the bank.
