know if there is anything to be cautious of when planting in tires? Any
feedback would be appreciated. Much thanks,

Tires are a notorious source of cadmium and are very dangerous to use in 
gardens or as structures in water supply.  I tried to get Bill to back off on 
that one in 1981, but  he had already published the idea and just dug in.  He 
didn't want to hear it.  Well, we all have our quirks.  Hopefully, mine and 
yours won't poison anyone.  DO NOT USE TIRES AROUND FOOD AND WATER.  Cadmium 
is extremely toxic.  Since tires are made of volatile organics, one assumes 
that other nasties are released too, but the cadmium is definite, unless tire 
manufacturing has changed in recent years.  It is added to the tire as part 
of measures to make the tire resist wearing out--last longer.  So if it 
weren't so toxic, it would be a good thing.  Ah, well....
