Automatic Tire Chains

Tire chains engage automatically

How fast can I go and turn ONSPOT chains on? ONSPOTs should be engaged and disengaged with the vehicle moving.  The system can be turned on with the vehicle going as fast as 25 mph.

How fast can I go with the chains engaged? Up to 35 mph

Do ONSPOTs work in reverse? Yes.  As the chainwheel hits at the tire centerline and the chainwheel is driven by centrifugal force the system will provide traction in forward or reverse.
