After about 15k miles they started to get noisy and rough-riding. The Goodyears were quiet and comfortable when they were brand new. I had to replace them last month, because they were down to 3/32 and were flaking rubber all across the tread on three of them. We had the Goodyear runflats on our X3 when we purchased it CPO in Oct of 2018. I love Michelin tires though, some of the best out there. Regular tires flex a lot more and deliver much better impact absorption, reduced noise, and in turn comfort. I don't care how comfortable the Michelin RFT is, the sidewall still transmits a significant impact force through to the chassis because of the stiffness required to drive on it while flat. I know, and OP probably doesn't want to switch after just buying tires, but tossing it out there.
