tires in gardening
What are your recommendations for use of tires in veg and sensory gardening. Any requirements, must they have drain holes drilled if being completely filled with soil.

I found some conflicting information. From Texas A&M https://agrilifeextension.tamu.edu/faqs/can-you-plant-vegetables-or-ornamental-plants-in-old-tires/, but there are others that do use them (not for vegetable gardening http://www.blackhillsgarden.com/index.php?p=1_71_Temporary-garden-from-tires and not 'permanent'.) https://www.thespruce.com/are-tire-gardens-safe-growing-veggies-848043 covers both sides of the debate.
