Arrive safe and on time with Onspot! Onspot is an uncomplicated, easy to use and the most reliable automatic tire chains system. On icy and slippery road conditions Onspot is activated by the driver – from the cab.

Automatic tire chains operate via a switch mechanism inside the vehicle. When activated, a chain wheel rotates, releasing chain strands beneath the tires. This provides immediate traction on snowy or icy surfaces without the driver needing to exit the vehicle.

Automatic tire chains were designed to give you traction on ice and snowpack at the flip of a switch. The speed of the vehicle causes the chains on the chain wheel to lift by centrifugal force; the weight of the chain determines the speed at which they lift and go under the tire.

Automatic tire chains use a faster, safer, and more convenient method: By flipping a switch, a chain wheel starts rotating and continuously throws chain strands into the footprint. You can read more about its properties here.

The ONSPOT Automatic Tire Chain System allows the operator to engage and disengage tire chains at the flip of a dashboard switch, in forward or reverse, without stopping, to enhance traction and braking in snow and ice conditions.

The Onspot Automatic Tire Chains system provides a level of traction on par with a single set of conventional snow chains. The system is permanently mounted and is ready to use at the flip of the switch, without having to stop the vehicle.

The complete automatic tire chain system includes as deployable wheel that is spun by making direct contact with the inside edge of a truck or bus’s tires. There are several short chains connected around the lower outside of these deployable wheels.

Onspot Automatic Tire Chains (ATC) After flipping a switch on the dashboard a chain wheel is lowered so it contacts the inside of the tire. The contact between the tire and the rubber-covered chain wheel causes the chain wheel to rotate, creating enough centrifugal force to extend the chains out in front of and under the tire.

With the flip of an in-cab switch, automatic tire chains use an air cylinder to deploy a chain wheel that continuously throws chain strands under the tires while the vehicle is in motion. The ability to activate automatic tire chains while on the move saves the driver time and keeps them off the side of the road with the danger of passing vehicles.

The Onspot Automatic Tire Chains system provides a level of traction on par with a single set of conventional snow chains. The system is permanently mounted and is ready to use at the flip of the switch, without having to stop the vehicle.
