This is important because the car doesn’t have a spare tire and there isn’t room to put one, not even a spare donut tire. Due to this problem, the majority of Q7s have runflat tires, and most have 19 or 20-inch wheels.
The issue is that no one produces 285/40R21 all-season tires, much less a run-flat version of that tire. Winter versions are also not offered.
The truth is that the tires cannot be replaced in the size that was originally installed on the vehicle.
