Why do we carry a spare tire around?

Guess it depends on where you take your B... On my 03C190P the spare resides inside the rear doors. In 10 years I've had 3 flats that I can recall. One, in Tok, AK, on a Sunday. One, Mother's Day in middle America. Most recently last Fall on a gravel road in northern NH. Road service would have been non-existent in the 1st and last scenarios, and a LONG wait on the 2nd. So for me, and the the way we use our van, the spare stays. I also carry a small air compressor and a tire plug kit if 1 spare isn't enough. If you confine your travels to pavement, you may have an argument to not carry one. I just find, to take full advantage of the nimble aspect of driving a B to out-of-the-way beautiful places, we need to be a little more self-dependent. And, for what it's worth, I do carry a spare serpentine belt. I may not be the one to install it, but at least I have the part to put on! That's the beauty of this past time - to each their own! ST
