ABOUT OPTION LAB WHEELS
The company was founded in April of 2013. Each Option Lab Wheel is constructed by enthusiasts for enthusiasts. They thrive on delivering the newest design, backed by a tried-and-true manufacturing process and a rigorous testing protocol, while keeping the wheels affordable. All Option Lab Wheels are either low pressure cast or high pressure flow formed to exceed the American SAE J2530, DOT-T, and Japanese JWL/VIA specifications. So that customers can enjoy a worry-free ownership experience, they put every wheel they design through rigorous testing. Each wheel comes with a limited lifetime warranty on the structure and a one-year warranty on the paint finish. Being a car enthusiasts themselves, they participate in national HPDE, time attack, and drift competitions. By interacting with fellow enthusiasts at these events, they are able to develop products that meet the needs of customers and the driver without exceeding the budget.
OPTION LAB WHEELS DESIGNEvery completed concept design at Option Lab Wheels begins with a computer-simulated stress test, or Finite Element Analysis (FEA). This computer simulation enables them to locate, if there are any, stress points on the wheel. Since computer simulation is merely a simulation, a small batch of test wheels will be cast following the completion of the mold. All of their wheels were subjected to three major tests: impact, cornering, and radial fatigue. The impact test is conducted by dropping an approximately 600 kg (1,300 lb) piece of steel at a 13? angle onto the face of the wheel. This test simulates situations in which a vehicle collides with a curb, and the spokes must remain connected to the barrel. The cornering test is conducted by shaking the spokes laterally under load (approximately 4000 Nm) at a high frequency to simulate the vehicle being driven through a corner at high speed/stress for at least 95,000 cycles. In contrast, the radial fatigue test is conducted with the tire mounted on the wheel and rotated for close to 2 million revolutions while under a load of approximately 15,000 Newton?s to simulate the stress on a vehicle's wheel when carrying all passengers and cargo.
In addition to initial testing, each Option Lab wheel is put through an X-Ray machine when it leaves the casting line. A computerized X-ray machine will examine the casting and detect any air pockets; defective products will be automatically rejected and recycled. Typically, a low-cost manufacturer will have a staff member manually inspect the casting, while some only conduct periodic inspections. After the wheels have undergone the majority of the machining process, they are tested for run-out and balance. Checking for leaks is another essential step in the manufacturing process. While the conventional method is to submerge the wheel in a water tank for 30 seconds while a person checks for air pockets, Option Lab employs a hydrogen gas test at approximately 70 psi for 60 seconds while computers detect leaks.
