Ive been fooling with risk for some time. My Honda Accord Hybrid came with no spare. Just an inflator and some slime stuff. It doesnt really make me uneasy, though I do keep another air pump, and lug wrench in the car. I did have a blowout once, and had to park the car, and go back with a snow tire to limp home... that’s an issue, but it’s something that is exceedingly rare for me and my local and highway use.
My BMW came with runflats, but when I learned that running on them destroys them, I realized they offer very little value in most circumstances I would expect to encounter. I’m more uneasy with that car, because they’re very low profile, and I don’t have four snow tires sitting at home... but it’s a risk I take, and there too I have extra tools to help deal with it should something go wrong.
Most of the other cars have full size spares, and I do keep an extra toolkit and inflator in each...
Knocking on wood now.
