So today as we were driving home from school, the boy proudly reads and announces to his captive audience “BIG 10 TIRES! Right, Mom? Big 10?” 
“Yep, you got it right, buddy”
(pause to process this information)
“But Mom, why is it big TEN tires?”
“Well, that’s just the name of the store”
“But, cars only have FOUR tires, not TEN!”
