X5 runs 275/315 and the M runs 295/315.
The tires are currently oem p zero that are 5 years old and never taken off during winter. I bought them knowing they’ll need replacing soon but thought could sqeeze one more summer out of them. But that’s not the case here, I’ve never like the oem perelli in previous BMWs and these seem to be no different. Im lighting up the tires at 70% throttle due to the combination of narrower front, low tread, temp damaged. It’s fine for daily driving I guess, but may as well swap them out now.

Tire shop: both 275 or 295 is safe on the diff/transfer case to run but 275 is off by a tad.
BMW parts: both is fine to run but be mindful at speed.
BMW service advisor: run 295, you don’t need to give BMW a reason to decline a warranty claim.
