So, Bob, you are blessed with tires that fail when it is convenient for you. I've had a lot of cars like that—when something goes wrong, it is almost always in my driveway.
I have never used the Tundra spare (fixed a truck tire myself in remote Chicken, Alaska) and a screw in a trailer tire leaked ever so slowly for a couple of thousand miles and I finally drove into a tire shop and got it repaired in Homer, Alaska. I've had one or two slow leaks at home where I did the same thing—pulled it off and threw it in the other vehicle, got it fixed, brought it back, put it back on. So, I don't think I've used a spare except to rotate tires since the '90's or even longer ago.
So, if you are lucky, you don't need a spare, but I never go anywhere without one either. When towing, also a compressor and a tire repair kit. People say those plugs aren't the best for tire repair, but the one I put in the truck tire in Alaska has been fine ever since—got to be several 10's of thousands of miles. I've used them before without a problem too.
So I guess I may be ready for using the spare too.
