If you are buying from a trusted dealer I would insist on new tires, less than on year old per the sidewall date code. A private sale usually means that you are responsible for your own PDI and can expect to make your own minor repairs. Amazon, Walmart and Lowes are good resources for parts, and of course the FRF will always help.
