Barracuda Wheels

If you can find a nice set of 14 inch rally rims you may be able to fit a 215 or 225 size tire depending on your fender clearance, but with the original rims a 205/70-14 or 205/60-14 would probably be about the safe limit. You may find a 185/50 is too short for your car - that’s a very small tire.
BTW there is a helpful tire comparison chart on tiresize.com that allows you load in the tire size you have and play with the numbers on the tire size you want.
DON’T FORGET - if your barracuda is still bone stock the lug threads on the drivers side will be reverse (clockwise to loosen).
The lug studs should be marked L and R.,
So when you take it to the tire shop, make sure you let them know so they don’t snap off your lugnuts.
