Regarding pressure/road damage: Polish roads in particular are marked with grooves created by heavy trucks. And we know for sure that it's because of trucks because it only happens on the rightmost lane, where they typically drive. Yes, trucks have more wheels and therefore bigger contact surface, but it only partialy compensates bigger mass. Pressure on road is still few times bigger than of typical car. Buses however, are big but not that heavy, so they are not as bad as trucks.
