The König Rallye Pro D Plus is the thickest and strongest snow chain covering full twin tyre packages used on heavy trucks.
The product is based on the same design of the König Rallye Pro D but featuring a thicker wire to offer the highest resistance and durability.
The König Rallye Pro D Plus is a supplementary grip device certified according to Ö-Norm V5119 thus fulfilling any winter equipment legal requirement for heavy vehicles.
The product is built following the traditional Professional snow chains construction, meaning that the chain is 100% manufactured in Steel, lacking of any plastic component, cable arch or anything else. Just superior quality steel and the most advanced treatments, plain and simple.
1 of 5The outer hook is the connection point of the outer side of the chain.
3 of 5Welded side rings are the most heavy duty side connections available for snow chains involved into demanding Professional activities. The rings are welded in place and, after that, the complete snow chain is subject to a case-hardening process which ensures that not only cross-sections are treated but also all the side elements, both on the internal and on the external side.

The cross-section design is generated starting from single diamonds in sequence. This is most typical cross-section design for offroad, truck and bus applications.
1 of 4Horizontal links alternated with vertical links: this is what the simple link configuration is about.
Vertical links are the ones more aggressive versus the ground while horizontal links act mainly as conjunction between the vertical ones.
The simple link technology is the most gentle versus the ground, it generates a limited vibration level and it’s the lighest available.
On the Rallye Pro D Plus, the cross-section links are extra thick offering the most robust and reliable chain cross-sections available in the heavy truck range.
2 of 4The product features a middle chain meant for connecting the two chain treads and for fine tuning the positioning the single chains on the tyre treads.
The chain features an ending hook which gets secured to a ring during mounting procedure
