The SSR aluminum alloy wheels used in this test feature five-spoke styling and a unique manufacturing process called Semi-Solid Forging (SSF). Using a process originally developed for aircraft and automotive parts which require high strength, low porosity and lightweight, SSF produced wheels use a special aluminum alloy which is heated until it has about the consistency of warm butter, and then it is forced into the mold under high pressure. This results in a strong, lightweight wheel that offers many of the traits of wheels forged in the traditional ways, but costs less to manufacture and therefore is available at a more affordable price. The lightweight 17" x 8" SSR aluminum alloy wheels on our 3-Series test car weighs a scant 17 pounds each.

The Pirelli P Zero Asimmetrico Max Performance tires used in this test feature a lightweight construction and an asymmetric tread design developed to maximize the tire's ability to put the power down whether accelerating, braking or cornering. Additionally, the P Zero Asimmetrico tread compound combines traditional carbon black with a special blend of silica and synthetic polymers to enhance wet traction and reduce rolling resistance. The P Zero Asimmetrico is used as Original Equipment on many performance vehicles, and for that matter, the tires in this test have been used as Original Equipment on the BMW E36 M3. The 245/45ZR17-sized Pirelli P Zero Asimmetrico tires weigh a respectable 21.5 pounds each.

When combined, the weight of the Plus One-sized P Zero Asimmetrico tires mounted on the SSR Integral alloy wheel results in a 38.5 pound Tire & Wheel Package which is actually 3 pounds lighter than.

On the road, this combination was praised for its steering feel and responsiveness, while it generated a small increase in ride harshness on bumpy roads. On the track, this combination was praised for its feel, feedback and responsiveness. It felt light and nimble, ready to transform the driver's input into performance. The car equipped with the lightweight alloy wheels and Pirelli P Zero Asimmetrico tires turned in the fastest lap times of the three combinations tested.
