Tire Size 68 Barracuda

Great looking car! :thumbsup:

Based on your pictures, I'd say you're already running the biggest tires you're going to make fit with that set of rims. At least really close to it. What size tires are on it now?

A 245/60/14 needs a 7" wide rim, and I would wager that's not what you have on there at the moment. Even if it is, it looks like you'd need more backspace that you currently have to make it work.
