Snow chains are chains mounted on vehicle tires to provide extra traction on icy, snowy, and slippery surfaces. They are used on tractors, agricultural machinery, and other vehicles that require increased grip and stability in winter conditions. Snow chains enable efficient and safe operation on ice-covered roads or deep snow.

There are different types of snow chains, including ladder chains, pattern chains, and studded chains. Ladder chains are simple and provide good traction in snow, while pattern chains have a cross-linked design that offers additional stability and grip on ice. Studded chains feature built-in studs or "spikes" for maximum traction on icy surfaces. Chains come in various thicknesses and sizes to fit different tire types and work environments.

When selecting snow chains, first measure your tire size and choose chains that fit precisely. Consider the work environment—studded or pattern chains are ideal for icy surfaces, while standard ladder chains work well in deep snow. If you need chains that are easy to install and remove, opt for quick-tightening chains. Also, consider whether the machine is used on roads or rough terrain, as some chain types may cause more wear on road surfaces.
