I parked behind another Model S today and snapped a photo to illustrate the difference between my 20-inch wheels and the OEM 21-inch wheels. Mine are the gunmetal TSW Nurburgring in 20*9 and 20*10, both ET35. Because of the more aggressive offset and width (especially in the rear), the TSWs fill out the wheel wells nicely, even though they are smaller. This also is a good look at the two new colors (Deep Blue and JRG Warm Silver). Thanks to LolaChampCar for the advice on these wheels.
