Hi everyone, I took delivery of my Model S before the Slipstream replaced the previous wheel version, so I currently have the double spoke wheels. I've been wanting to replace these with a newer set, hopefully something sexier, but I'd really like to stick to the 19" rather than move to the 21" as I've heard the larger wheels take a hit on energy efficiency plus a few other issues. I'm hoping to use this thread as a means for the experts here to list out the available 19" options, along with any pros/cons, any tips, or other feedback, to help potential upgraders decide on the options available. Maybe even a mention whether the OEM tires can be used on the wheel or if a different size is needed. So far, I've seen the following mentioned around the forum: Tesla Double Spoke Tesla Slipstream T Sportline TST - » TST 19″ Tesla Model S Wheel Mentioned on many threads Rial Lugano - http://www.tirerack.com/wheels/WheelCloseUpServlet?target=wheelCloseUp&wheelMake=Rial&wheelModel=Lugano&wheelFinish=Titanium+Gunmetal Mentioned on Stock Wheels vs Rial Luganos What others are there?
