Take a look at the Polaris scooter wheels from Longway. To keep the weight at a minimum and the durability at a maximum, the core is made of high-grade 6061-T6 alloy with air trapped inside the hollow core for a sturdy wheel that gives you no excuse to stay on the ground. Longway has designed the wheel with a round profile to give you a stable wheel with less friction, thereby adding speed to your performance.
