Abstract
A continuous flexible track for extending about a plurality of aligned wheels on a vehicle or track module, the track includes an outer ground-engaging surface and an inner wheel-engaging surface having inwardly-projecting wheel-engaging lugs. Each lug has a proximal end, a distal surface, front and back surfaces and opposite side surfaces. Each lug further includes a flex-groove extending between the side surfaces and from the distal surface toward the proximal end, thereby dividing the lug into two portions to allow around-wheel hinging motion. In most preferred embodiments, a lug-receiving cap may be positioned over and replaceably secured with respect to each lug. A method for prolonging the useful life of such a track is provided.
