Wheel size selection, Need some schooling! Options

[KevinP]

I was wondering why someone would want to go to a 17 inch wheel on there 914 from the stock 15 inch.

I now see you have an increase in wheel and tire weight with the increase in size and the chances of have more problems with handling and balance. Are they reducing the difference by going to a low profile tire?

I still see that you have more rotational mass than stock...this i see as a problem or the potiential for.

See if you can edu macate me here............TIA

Some random thoughts:

I would say generally, as wheel diameter increases, tire height decreases. You still need to fit into the wheel wells.

I run 205/50/16 tires on my 16"wheels.

The stock tire size for a factory delivered car was 165/80/15. I haven't found that size in many years.

Higher performance tires tend to have a lower and stiffer sidewall height, so to maintain overall tire height you need a larger diameter wheel.

The closer you match the factory tire diameter, the more accurate your speedometer will be as well.
