I change tires, studs to summer tires and back on my F350 twice a year. This is not the easiest task. With this trolley, the task was almost fun. Loosen the cleats, raise the jack, roll the dolly under the tire, remove the lug nuts, lift the dolly and simply roll the tire off the hub. Roll the tire, roll the spare in front of the hub, slide the dolly around it, lift the handle on the dolly and roll it into position. If the lugs don't line up, simply rotate the tire clockwise or counterclockwise
