These are made by SIMMONS in AUSTRALIA (simmonswheels.com.au) - this is a 17" version. They make them in a range of diameter, width and colors. SIMMONS has been around for many decades and make quality products. I purchased my first set of SIMMONS near on 35-years ago, and they are still going strong on the car I sold. They also have other designs.
