One of the critical things to keep in mind when grooving your R4 tires is to not compromise the integrity of the lug to the point where you introduce the possibility of chunking . Grooving to close to the edges of the lug or multiple groves to close together will increase the chances of a lug chunking when operating on rocky or rough terrain.
This is the pattern I used on my 2555, the primary purpose to grooving the front ties to to help in preventing lateral movement when pushing a load forward. This pattern has increased my forward traction by about 50%. I still experience some lateral movement (side slipping) on slanted surfaces when there is a hard pack snow or ice base and the new load of heavy wet snow.
