As highway tractors become more Aerodynamic it becomes more challenging to use chain. Side fairings and drive tire fairings are appearing on almost all new highway trucks. Chain becomes very difficult to install and if there is a failure these very expensive components can be damaged.
Autosock, approved in almost all jurisdictions in North America, allows drivers to quickly install their traction control and be assured damage will not be done to their vehicle.
Another problem solved using Autosock!!!
