If I call them, can they tell me if they have a particular tire & do tires come on the rim if its a stock rim?

They will not tell you if they have a particular part only if they have make and model as well as how long car has been in the yard

They have a section of all different size tires all in a row on racks before you walk into yard. It'll cost you $2 to get in, not a bad amount to ganble even if they don't have your size

No they recycle the rims they will say what size tires they have.but not the brand name of the tire.
