You can salvage the wheels off wrecked shopping carts. .usually victims of the snow plow operator. You can find them out back of your supermarket. I have made carts for years and those wheels have no problem supporting a car or truck.. I likely built my first pair of car skates 25 years ago,,and being able to move vehicles,tractors around or just up against the wall ,,,they are real space savers
