Some people think that I'm strange for carring two spares in the truck for longer trips.
I have a Dually and on trips I still carry two spares. I actually am going to have a third soon because I have an extra tire and was just given an extra wheel. I really don't like being stranded. Paranoid or not, better safe than sorry when you're 1000 miles from nowhere.
I rarely ever have a blow out on my flatbed with triple axles, I keep pretty good tires on all the time. They seem to be a common tire here to find. For $600 can put a whole new set on.
That's about what the shop near me quoted. $95/ea mounted and balanced with new valve stems. If I decide to keep what I have, I'll probably order a set of these:

They come mounted already (which I will verify) and then I'll have my old set as spares just in case.
I'm also going to buy one or two spare sets of bearings to keep on hand after I repack the current bearings. Did I mention I hate being stranded?
