I have used them on my paved driveway and have never had any damage to the driveway with them. I will admit that they can do a lot of damage if your driveway isn't a quality job or you start spinning the wheels and are not moving. I would use the bar chains on a dirt driveway, and the standard link 2 link chain on a paved driveway for the least amount of friction damage. As I have said in the past, everyone's conditions and needs are different and they must decide for themselves what is best. The pictures are to show the differences to those that are not experienced with these items..... as the old expression goes.... a picture is worth a 1000 words.... Junk.....
