DIY RC Car Tires - 2.2" Silicone Rear Buggy Tires

2.2" Rear Buggy Tires made with 30A platinum cure silicone.
Running JConcepts closed cell inserts.
Even though silicone rubber feels like it would make a great tire, that was not the case here. These tires performed the worst of anything I've tested on dirt - even worse than carpet tires on dirt. They barely survived use with a 17.5t motor and ripped almost immediately when using a 10.5t motor.
