That Uno looks really smart, killfr0g!
At first I thought it had lower side-cladding in a contrasting colour (like my 164 - see pic!) but then I realised that it's just the effect of the pinstripe!
The wheels are pleasantly tasteful. I think you're right that with those wheels, the taller tyres don't look out of place. With the standard flat-style wheel covers though, the tyres might not look as good! Different tyres also bring different characteristics, e.g. you probably have a slightly smoother ride, but there may be more tyre distortion during cornering?
