Michelin Airless
Former automotive engineer chiming in. "Tweels" have been around a long time, but have always failed in terms of "NVH" (noise, vibration, harshness). Michelin is claiming that this generation of tweels are appropriate for passenger cars, which means that they <i>think</i> they've solved the NVH problem.<p>They seem to be marketing these alongside EVs, I wonder if they're only really intended for lighter, compact-style cars. (Edit: I'm talking about EVs like the BMW i3, which <i>are</i> on average about 1000 lbs lighter than the cars most Americans drive, ie, the CUV/SUV form factor.)
