It's time for me to replace the current set on my 2011 535 - Goodyear Assurance ComforTred Touring). I called the dealership and they quoted me $300 a tire and with installation the total came to $1,500. Sam's will do it for $946 after the rebate. All the other tire places were within $100 of their quote. I don't understand why a dealership would upcharge that much. I put the goodyear on because I hated the run flats. It was comfortable, quiet and lasted over 70k miles. Any recommendations on another tire? I don't have the sport option so didn't see the need for a performance tire.
