Just Delivered
I went with the OEM Michelin Primacy MXM4 All Season Run Flats. Staggered sizes front/rear. (I grabbed the tire specs from The Tire Rack). I still like the benefit of run flats especially when going cross county with wide open spaces. But that’s going to become less of an issue soon.
Costco didn’t offer these. And the dealer price was crazy - for tires and sensors. The dealer’s total bill would have been over $3,000. Damn.
So I went with my favorite local tire shop. I ordered the MB sensors because I wanted MB parts and they got the tires. I've never seen Best Before dates on parts - the TPMS sensors. They're new and better than my old ones.
I used MB of Devon because they sell wholesale or close. Much better than full dealer prices.

Quiet comfortable elegance going down the road. And I still love the RENNtech tune. It will really move when needed. Glad I replaced the tires before this trip. Even as run flats they were quiet and comfortable. Don’t be scared of run flats.
Some pictures from MD to SD.
I use this dash layout/design because it shows the speed limit at the bottom. In the Classic design which I like more the speed limit is blocked by the speedo needle at 80mph.
