Results of field investigations on the impact of selected driving tyres (12.4-28, 14.9-28, 13.6-36) and guiding tyres (6-16, 7.5-20, 12.8-18) on light soil compaction within and close by the wheel tracks were presented. It was stated that all the tested tyres cause significant unfavourable increase of soil compaction in arable horizon within the wheel tracks. However, near by wheel tracks the similar effect was produced by 12.4-28 and 13.6-36 tyres only on the depth 20-25 cm and at much less applied loads.
