I myself have never used chains. However I do occasionally come across skidders on some trails I go to. With their tires as tall as I am you think they would be fine like that but no, they have huge chains around those tires. and besides the fact they are used to haul trees out of the forest, I dont really see and damage to the trail itself because of the chains. if anything the people who do brake stand in soft dirty areas do more damage.
