Can I dismount my own tires from the rim?

Ordered some tires for the truck on sale from tire rack, and figured I used their recommend mobile installer. They had to reschedule, and gave me a discount. All fine so far.

But, my town will take the tires on trash day, and save me the disposal fee. Trash comes Friday morning, tire people rescheduled to Friday afternoon. Assuming my jacket stands for my Miata are tall enough for my tundra, is there any way I could dismount the tires from the rim to toss them Friday morning, instead of having them hang around another week?
