From E30 Zone Wiki
Welcome to the Wheel register! On this page we are compiling a list of every wheel known to fit the E30, including all of its technical parameters.
The standard E30 wheel fitment is:
- PCD: 4x100
- Centre bore: 57.1mm
- Offset: ET 15-35
- Bolt: M12x1.5, 26mm length
When choosing your wheel, especially its size, it is important to remember the rolling radius; the overall size of the wheel including tyres.
The standard wheel and tyre fitted to the E30 was a 185/65R14, giving a rolling radius of 298mm. If running the 15" BBS, the tyre size was 205/55R15. If you are increasing the size of your wheel to 16" or 17", you need to pay attention to your tyre size, because it will affect your gearing as well as your speedometer. Learn more about calculating your tyre size.
