Since FC7cuda inquired about modern equivalent-sized tires, I thought the tires mentioned were listed on his tire placard. Therefore, I thought that he was looking for an OEM-size tire without changing pinions.

Thanks for reading the article and for finding a typo. I meant to write P225/70R14 and I've made that correction.

Since I have a 1965 Barracuda of my own, I just used those tires as an example for the math. I suppose I could have used a later model as an example but I thought that the older cars originally equipped with 13" tires would be more likely to be facing problems finding replacement tires. I'm not sure why this would be comical.
