I have a small toolbox in the frunk that still leaves room for groceries. Inside the toolbox I have a tire patch kit, low profile scissor jack, small compressor, and socket/wrench for the wheel nuts. I always put such a kit in any vehicle that we own.
I want to be able to remove the tire and get it serviced (or patch it) no matter where I am. Patch kits work well in a pinch to keep the tire from getting ruined. You can only travel so far with no air in a run-flat before you have to replace it.
When the time comes for new tires, for sure I will go with non-runflat tires. I did that on my wife's X3 and the ride improvement was very noticeable.
