Hey Bill,
Yeah, my tire wear is pronounced in middle, especially on rears. My confusion is whether that is because of the higher pressure that the tire is at when it's warm ( in my case around 44psi/rear, or are the tire(s) just really not good wearing tires); they are the Pirelli Run Flat's that came on car when I purchased it. As I've said before, I check pressures at least once a week and have set them to placard level 36f/41r. Maybe I'll set them to 34f-38r, but it's probably to late for this set of tires. My next set of tires will still be Run Flats (unfortunately) because I will still be in warranty (48 mo. not up until 12/2020) but as soon as possible I am switching to non run flats.
