There is a place that has reflective wheel stripe kits for about $20. They have various colors, 9 I think, and have them in 1/4" (6mm) wide pieces. A kit is 18 pieces curved to fit your diameter wheel. They give you 2 extra pieces just in case you mess one of them up.
This sounds like an inexpensive mod and also adds some safety because of the reflect part.
Here is where it is:
eBay Store - GLSigns Wheel Stripes and Decals: 17in Sport Bike Wheel Stripes, Harley and Metric Cruisers, Honda
They list the colors as-
Black looks Black under normal light and reflects Gold
White looks Light Silver/White under normal light and reflects Bright White... Our Most Reflective
Dark Red looks Ruby Red under normal light and reflects Fire Orange
Red looks Red under normal light and reflects Fire Orange
Orange looks Orange under normal light and reflects Bright Orange
Yellow looks Yellow Gold under normal light and reflects Bright Yellow
Green looks Street Sign Green and reflects back Bright Green with a Blue tint.
Blue looks Interstate Sign Blue and Reflects back Sky Blue
Purple looks Barney Purple and reflects back lighter Purple
I have not the faintest idea what Barney Purple is....
