Tire Size Opinions

car would handle an accelerate better with lighter smaller wheels

I would like to use the 15x7s, sure, but if a smaller rim/tire is better, ok.

Wasn't sure if a smaller tire was necessarily better or why.

15s definitely have more options.

Or, is there a tire for the 15x7s that would be the same diameter as the 245/60R14 on it now.

Basically, is it about overall diameter of the tire/rim?
