I went to look at a 2015 Fiesta ST today. I'm picking it up Tuesday!! Had a question for you guys. I was under the impression that this came with Potenzas from the factory, so I honestly didn't pay too much attention to the tires. After the test drive and looking the car over some more I noticed it had Michelins on it. Is there a chance that this is an all-season tire? Wasn't that an option for the 2015 model?
