Snow Treds

Sno-Treds from the Detwiler Corporation, offer a solution to the winter traction problem.

They are a series of flexible bands, made of a durable polyurethane elastomer, which lie flat against the tire during regular driving. In snow, when the tires begin to slip, these harder-than-rubber, teeth-like bands twist downward into a “paddle-like” position that bite into the snow to provide the needed traction. The same principle applies in sand or mud. Because SnoTreds are harder than tread rubber, they also are effective on hard-packed snow.

Like chains, the bands are detachable and are intended for use only during snow emergencies. They are lightweight and can be installed in approximately two minutes without having to jack up the car, according to the manufacturer.
