So I got delivery of my car 9/15/13. I put the order in after the price increase which meant the upgraded Michelin Primacy tires. Well my car came with Goodyear tires instead. Informed the service center about the mistake and they said they would look into it. I just received a call from California stating that if I keep the Goodyear tires they will cover my first annual service. Obviously this is a worth $600. I know that some people were mistakenly given the Goodyear tires and Tesla exchanged them out with no hassle. Of those people did you happen to drive with the Goodyear tires and noticed any difference when they exchanged it with the Michelins? I feel the Goodyears have great grip but I feel every bump in the road. I am wondering if the Michelins would change that feeling. At first I was leaning to taking Tesla's offer but after looking up more information it seems like the Michelin tires are better quality. A quick search it appears the Goodyears go for $150 and the Michelin for $250. So Tesla's offer is not unreasonable but wondering if I will be missing out on a nicer ride for the next 20-30,000 miles. What do you guys think?
