I'm getting all my tires changed on my 2003 Rio. I ordered GoodYear tires from the dealership and then dicovered the OEM tires are actually made by Optimo. I have only taken my car to the dealership and used OEM parts for everything, even down to oil changes. Should I exchange the GoodYears for the OEM tire? What are the advantages/disadvantages for OEM and non-OEM tires?
