I have a 1992 ford fiesta just bought and i need some tire info?

tires could be very tricky, I advise you to pull out one tire when you buy a set and try it physically on the car if they fit, it does not matter if they are 13 or 14" for as long as they sit and fit properly that would do the trick, for the rest you might get advise from ford dealer of what size rim and tires they would advise, however what about the size that is on the car now? good luck mate ....
