I am in the market for an upscale SUV, and the Q7 is quite appealing. I was discouraged to find that the 2017 Q7 has no spare, only run flat tires. We do not live near a dealership, so I do not know what tire models are OEM on the car. I would be interested in knowing the mileage that owners are getting from their run flat tires, as I realize that they are not without their expense. (I realize that this is just the first model year and that many people will not have had to replace their tires, or I HOPE that many people will not have had to replace their tires yet! I am wondering how the mileage appears to be holding up... Also, if you post, please indicate the tire model...)

Thanks
