I assumed it was a flat tire . Which was going to be impossible to change considering I did n't have the right shoes . I pulled over , and as I glanced in the rear view mirror , I noticed something shining .

Question: what is the reason my shoes preclude me from changing a tire ?
Answer: I do n't have the right sized shoes for tires .I need my brake shoes to change a tire .Working with a tire is messy and you need sturdy shoes .None of the above choices .
