I looked at several brands and the Michelin tires are in line with pricing for your vehicle. I don’t think I would buy a cheaper tire since fuel economy, comfort and safety would be affected. You have a premium vehicle and I think you need a premium tire. You might try getting the tires at a wholesaler even if you have to drive a 100 miles to save the money. Do you have a Sam’s Club nearby. They sell Michelins.
