Power Wheel is a removable disc that fits inside the vehicles tires. Inside are twenty metal bars (steel-tipped for off-road vehicles and rubber-tipped for cars to protect asphalt) that can be manually or automatically telescoped out beyond the circumference of the tire to raise the vehicle slightly and grip the road. When you’re clear of the trouble spot you can then retract the bars into the disc. You’d need one Power Wheel set for a regular car’s two “active” tires and two sets for a four-wheel-drive vehicle. Before starting on your journey, you could attach them to the permanently installed adapter in your wheel hub. Alternatively, you could keep the discs in your trunk and use them when you encounter slippery or other traction-challenging conditions. More...
