I have a 2010 Mercedes ML350. The spare tire was removed on this model to make room for the DEF fluid tank. So run flats are required. I live in the center of the US and regularly drive to both coasts, about 35,000 per year. When pulling a trailer, I have a full size spare along. The tires are a disaster, but, they can be repaired. They can be repaired if they have not been driven on flat, but you have to find someone willing to do it. And I use the Pirelli for the warranty, which by the way is void if you do not have a receipt for them being rotated every 5000 miles. Here is the kicker, on a 4Matic (4 wheel drive vehicle) you cannot have a tire with more that 3/32 difference from the other tires. So if you have a flat and your tire wear is greater than 3/32, you have to replace all the tires. The warranty only covers the damaged tire. I guess you need to keep a box of sheet rock screws in the car to drive over if a tire gets damaged! The run flats are bad news, I know, wife or daughter getting home, etc. Keep the cell phone charged and have AAA come and change it.
