Man Invents New Tires That Let You Drive Sideways
 
   
 

 
   
   
William Liddiard shows his Toyota Echo gliding sideways thanks to omnidirectional tires that can roll inward upon themselves. An external motor powered by the car's battery allows sideways travel at about 1 mile per hour at the flip of a switch.

This is a world first bolt-on application for anything with wheels. Designed to be used in all weather and road conditions. They are stronger, faster, and more accurately controlled than prior art. They can take a beating. The tires "can" have the same build characteristics (siping, grooves, rubber compounds etc.) as regular tires. Now you can drive in all directions, and turn on the spot, when needed. These are proof of concept prototypes to show that they work. Finished wheels will be refined to target application requirements.

"I did not want the tires to move too fast at road speeds so I used a high gear ratio. The incredible torque directly on the tires is much more than needed. I now know I should have used a lower gear ratio. Faster speeds are definitely possible. Now ANYTHING with wheels can be omni capable (not just cars)."

Liddiard estimated the cost of his system to come in at around $2,000 Canadian dollars (U.S. $1,541) per tire, adding that the price could change depending on the vehicle.
