Keep in mind, generally they are carrying a load of people in them. Anywhere from a few to 20 or if they are using what is their version of a buckboard wagon that is loaded with bales of hay or equipment, the weight load of a metal wheel compared with an inflated rubber tire is much higher. A rubber tire's 'footprint' distributes the load more evenly than a 3 inch steel wheel and that is where the damage to the road surfaces comes in. The steel wheel cuts into the roads while the rubber tire floats more on the surface.I just don't see that.... those buggies must weigh nothing compared to a car...How much damage can those light things do?
