Definitions
- the invention relates to a commercial vehicle tire chain, especially for forestry vehicles, tractors and wheel loaders.
- the invention also relates to a commercial vehicle tire and a stud plate for a commercial vehicle tire chain.
- Tire chains with large rings resting on the tire tread are currently used in the area of forestry commercial vehicles to increase traction on slippery surfaces. These rings are made of relatively strong wire with a diameter of 19 mm to over 30 mm. Due to increased requirements regarding the soil compaction generated by forestry commercial vehicles, increasingly larger tires are being used. So far, a larger ring has simply been used for larger tires. However, as the size increases, these rings become more difficult to manufacture. This makes heat treatment problematic due to the large diameter. In addition, high forces are required for bending.
- the invention is therefore based on the object of creating a commercial vehicle tire chain, in particular for forestry vehicles, which, despite increasingly larger tire sizes, is simple to manufacture and in particular is also easily scalable with the tire size.
- this object is achieved by a commercial vehicle tire chain, in particular for forestry vehicles, tractors or wheel loaders, which has a plurality of stud plates connected directly or indirectly to one another via chain strands, each stud plate having at least one stud for improving traction, which extends from a top of the Stud plate extends away.

- a commercial vehicle tire chain according to the invention can also have a row or more than two rows of stud plates. If there are at least two rows, cleat plates of the two rows can be offset from one another in the circumferential direction instead of being arranged at one height.
