The document describes a new wheel design called the planetary wheel or "shweel" that replaces air-filled tires with steel-armored shock spokes for improved safety, comfort and efficiency. It analyzes the shweel's higher rolling resistance ratios, shock capacities, and potential efficiencies compared to traditional tires, finding that shweels with higher compression ratios could achieve up to 4% lower rolling resistance and 30% less drivetrain wear while providing more impact resistance than tires. Contact information is provided for questions about the shweel technology.
