Tell him, "I'm sorry, I wasn't asking for a tire for a Bentley, just a freakin' spare for the trailer." Funny, but when i was walking around the local CW, it seemed that All the trailers had a Tire Mount and in some cases a Spare on it.
I asked the salesman trying to get us to buy a trailer about the spares not being there, and he said, "They take them off and store them inside since we have an open lot to the street. It keeps the spares from walking away during the night."
So to my thinking, they should come with a spare...as stated above, if they don't that is just wrong.
