Old Tire Size Conversion?

The front tire is a G70-14, that is also marked 205SR-14

So, from the link I assume I should look more towards a 205?

235/60R14.......$110-$150 each
205/70R14.......$50-$110 each
205/80R14.......not widely available

Now for the size difference:
235/60R14: 25.1" (tall) x 9.25" (wide)
205/70R14: 25.3" (tall) x 8.07" (wide)

Sidewall height is pretty close to each other

Remember, the G70 is the front tire
