So T Sportline is coming out with some 20" wheels soon. Given that there are actually some non-performance tires available for this size (http://www.tirerack.com/tires/TireS...h=255/&rearRatio=40&rearDiameter=17&zip-code=), I'm mildly interested in these. However, I already have the 19" TST wheels, so I'm wondering if it really looks that different. Are there any sort of side-by-side comparison shots that show 19" wheels and 20" wheels on a Model S?
