2013 AWD. Ditched the runflats at 1K and replaced with Michelin Pilot Sport AS. The run flats had pathetic performace. Bad handling, poor traction, bad ride. I told my wife I wanted to replace them with regular tires after about a week driving on them and she wanted to wait until they wore out. Then someone cut us off and I hit the brakes and the car just slid on dry pavement. It was bareley a hard stop. So I got the go aheat to replace them and what a difference. Run Flats suck. You cannot fix them. If you are travelling you may not be able to get a replacement locally as there are less options in run flats and less are stocked.
I purchased a new spare tire and mounted in the trunk behind the driver side seat. I also have a hitch mount spare tire carrier to use if we need the space. In 10 years I have never had to use the spare tire. I have always been able to use an air pump to refill and get to a Costco to have the tire repaired for free or install a plug and later fix at Costco for free. I don't recomment using slime or any other sealant as the tire guys hate dealing with it, it voids your tire warranty and is really difficult to clean out of the tire.
When we removed the run flats I intended to sell them. Two of the four tires were damaged during removal. The machine that pushes the sidewall broke the sidewall on two of the tires. The sidewall on a runflat is about 1/2" thick and is inflexible. Pushing on the sidewall caused the sidewall to crack in the middle about 1/4 to 1/3rd the way around the tire. I was furious becuase the tires were destroyed. They tried to claim that they were damaged before removal stating that runflats often have that damage when they remove them. I reviewed the video. They had difficulty removing them but there was no tool gauging the side wall as I had assumed looking at the damage. Turns out that they are often damaged on removal which may be why they say you cannot fix them.
Buy a spare, air pump and possibly a plug kit and get real tires that are cheaper, perform better and are easier to find and replace.
