The steel rims rot in the northeast, AAA will not change them if they too bad. My 1976 Corvette's spare, sat in a protective, plastic clam shell and was easy to remove. The tire would slide out. I checked it and was surprised to see it was in like new condition(in 2001). It was a steel 'rally' rim. I recommend putting a tire cover on them(like on the jeeps). I have a hard cover off a Toyota FJ cruiser. I bought on craigslist for $20. They use a similar size tire. Ford should put the correct size tire, especially after the 'Firestone rollover' recall.
