The Amish that live about 10 mile from me have rubber tired tractors and combines. They only use horses for transportation amoung theirselves and to go shopping. All the wagons and machinery have rubber tire. Two more Amish settlements around me have no rubber tired machinery, but have crawler tractors to use to load and haul stuff. One of them put rubber tires over the steel wheels so as not to tear up the roads so much and make the wheels last longer
