Why does the wheel PCD differ across manufacturers? We all know some common wheel PCD sizes used by manufacturers today -
- Ford uses 108 PCD
- Fiat uses 98 PCD
- Maruti uses 100 PCD
- Mercedes uses 112 PCD
- BMW uses 120 PCD
... and so on...
My question is - why do PCD sizes differ across brands? It is okay to say that car manufacturers like to maintain their individuality and stick to the size they have been manufacturing all along, but is that the real motive? I was reading up on the net about this topic and found some links for newbies, like the one below which explains what is PCD - http://www.nice-wheels.co.uk/pcdandoffset.html
I couldn't find information on how PCD size affects vehicle performance in any manner. Does it? If it does not influence any technical aspect or provide any advantage, why do car makers stick to their specific sizes for wheel fitment patterns? Tyre gurus, please educate us on the motives of this practice.
Wouldn't it be so much easier for car makers to all follow a single universal PCD pattern? Not to forget, it would be easier for anyone trying to swap their wheels for new aftermarket alloys ![Big Grin](https://www.team-bhp.com/forum/images/smilies/biggrin.png) .
I couldn't find any thread dedicated to this query, so I created a new one. Moderators could please merge this thread if another similar one exists.
