You will never be lifting all the weight at once, only one side. But with any jack, you need some wooden blocks to spread the weight out over at least a foot or so. Letting that small round jack tip support a ton could bend the frame, IMO.
They make a device for driving one tire up on and it raises the other high enough to change the tire. That's probably the best method, but they are expensive and it's something else large to haul around that you may never use.
