175/55R & 155/60R. Don't know which is front or back.There were various tire sizes offered from the factory over the years:
155/60-15 front 175/55-15 rear
165/60-15 front 195/50-15 rear
175/55-15 front 195/50-15 rear
Which do you happen to have?
(Anyways, Matt seems to be very knowledgeable with regards to tires...)
We noticed after owning this car a few weeks that we had one of each mixed up on the front and back. I thing catycorner. I think I put the narrower on the front and wide in back, but not sure.
