For some people all the alleys are their dump.
Kelly of Westover Hills has this message:
FOUND! Whomever lost their seven tires, I found them behind our house. If they are yours, please comment or PM me so we can return them to you ASAP, m’kay!
The thread posted on Westover Hills Neighborhood Facebook has some clever re-uses of the tires and all the tires have been claimed. Thus avoiding having to take them to the Richmond Southside Transfer Station (3520 North Hopkins Road).
