Colson Performa Wheels have long been a favorite of combat robot builders. The wheels in this series have been used on all sizes of robots, from 1lb Antweights to 340lb SuperHeavyweights! They are very durable, and provide excellent traction.
Performa wheels offer the advantages of both hard and soft tread materials in a single wheel. Like a hard tread wheel, Performa rolls easily and is very durable. Like a soft tread wheel, it rolls quietly, protects floors and resists impacts with a cushion ride. It also features maximum weatherability, low temperature flexibility, resistance to chemicals, water and steam, and rejects floor debris such as metal shavings. Non-marking thermoplastic elastomer tread is permanently bonded to durable polyolefin wheel core. The rubber is 65 ±5 Durometer Shore A scale.
If you wish to use as a drive wheel, you may need to add a separate hub or make a keyway.
