If I am simply swapping wheels, I leave the car on the jack and slide the wheel that I just took off under the side of the chassis (not all the way under the car as it can simply push through the floor pan depending on where you put it exactly) before I mount the other wheel. I guess there is a tiny chance the jack might fail during the 30 seconds that it takes me to remove and slide the wheel under the car, but I think that is highly unlikely if you have a good jack that is in proper condition. If I plan to work on the car for an extended period, I put it on jack stands (and still slide the wheels under the sides of the chassis).
