Non-slip inflatable device for motor vehicle tyres based on a device which covers the tread of the tyre and which has elements on its outside face making it non-slip, and characterised because the device as such is of a low-rise straight, rectangular, elongated parallelepiped-shaped inflatable resistant element.

A utility vehicle tire chain, in particular for forestry vehicles, tractors, or wheel loaders, has a plurality of cleat plates directly or indirectly connected to one another via chain strands, wherein each cleat plate has at least one cleat to improve traction which extends away from an upper side of the cleat plate. The solution according to the invention can simplify the manufacture of a utility vehicle tire chain and improve its stability.
