Only thing I insure is umbrellas. They never last more than 2-3 years and a 7 year replacement plan for like 8.99 is a reasonable deal. Anything else I tend to just go with credit card purchase protection and MFR warranty.
What credit cards offer protection these days? All of mine seem to have done away with it. For umbrellas, I bought a Tumi, which is insanely expensive (was $40 when I got it; I think it's closer to $60 now), but which has a lifetime warranty.
> I've been driving for 36 years now and have never had a tired damaged more than the very occasional puncture.
I typically go through a tire a year. The city I live in (Seattle) will pay to replace the tire if the loss was due to a pot hole, but you have to take a picture of the pot hole, which can be a bit hard to do in many circumstances.
There have been years where I've paid more for tires than for gas. :/
