I just acquired a 1995 F350 4x4 diesel with a dump box. Got a really good deal with what seems like a well maintained low mileage truck, but ... this is the first truck I have ever owned, so pardon my ignorant questions:
- After getting it home I realized that where I thought I would find the spare tire, I can only see the rear fuel tank. Is it normal for dump trucks not have a spare with them?
- I hope I can find an inexpensive used replacement. Am I correct that I just need to have a spare with a front rim, and if I get flat with one of the tires in the dually I can still drive it home?
This is for starters. I have plenty more dumb questions to come, but did not want to overwhelm you with my first post.
All of the rims on a dually are the same, the rears are just two fronts mounted back to back. If you get a flat on one of the rears you should still change it as soon as possible. Depending on the load on the truck at the time a flat on one rear tire can be hazardous. If the truck is loaded you will overload the remaiing inflated tire and cause it to fail also, even unloaded if you run with a flat on one of the rears the deflated tire can heat up and disintegrate causing more very extensive damage ( brake lines, fuel lines, body damage). How you ever seen large chunks of tires laying in the interstate, that is usually what is left of a big rig tire after it has gone flat and still run on.
just about every dually i have ever seen did not have a spare tire under it. it was usually mounted on the cab shield of the dump body if there was one at all.

Thanks for educating me on the risks related to driving with the flat. Today, I called the guy who sold me this truck and he said people don't typically carry spares with duallies. If you have flat in front, one can move one of the rear tires up front, and if you have flat in the back, one just pulls out the flat. In either case there would be no driving with the flat, but one dually would have temporarily only a single wheel. As you point out this would not work with a loaded truck.

That is starting to sound like the only workable idea. Any idea where to find some kind of a bracket to do that?
most of the ones i have seen were done by simply welding 2 or 3 bolts to the cab shield, then bolting the tire down solid with the hub face flat and the tire sticking out in the wind.
