So I know absolutely nothing about tire sizes. Right now I have a '72 Scamp with some really old tires on it, E78-14 on the front, and D78-14 on the rear. I found a used set on Facebook, 195/70/14 with 50% tread left for $80. Will these tires work? I just need something so I can move/drive the car around while I fix it up.
