Clean all of your tires with a good kitchen de-greaser. I like awesome. Makes me feel awesome.
Choose an area to position tires. Two tires wide and Three tires in length.
Space the tires apart. You can measure your box spring to figure proper spacing. Or just eyeball it.
Choose tires that have similar height.
Space them equally.
Make sure to keep space from the wall to avoid rubber wall skids. Seriously.
Voila! You now can position the box spring and then mattress over the tires. You may have to adjust the tires. If bed squeaks use WD-40. Haha.
