Just some pics of a spare tire mount that I built.
This trailer's pretty high, has space for a spare under the dump bed.

A hitch-pin holds the tire latch in place.

What happens if you have a flat while a full load is in the bed?

Looks like you crawl under and pull the pin. I mounted my spare under my car hauler really nice and out of the way, however I used a crank down spare tire mount from a pick up truck. The crank handle is mounted in the tool box on the trailer. I also made sure and put the access on the right side of the trailer just in case I needed to lower it while on the side of the highway. The less time I have to spend near the driving lane the better.

Excellent idea but you do know that nice looking tire and rim will soon look like it was submerged in a river for a decade or two !! Wrap it in a couple industrial bags maybe?? I know my underside spare rims get reeeaaalllyy rusty.

Thanks guys.
Fido If I ever need that spare its gonna be the most beautiful wheel Ive ever seen.:thumbsup:

If the bed was empty, I think the other 3 tires would suspend the flat one.
I wonder if I would even notice it was flat?
Maybe it can be driven flat & empty, Id have to see how it looks.
Maybe it could be removed and drive with just 3 wheels.
Seems a blessing to have my flat while empty. ;)

Loaded is the primary reason that I wanted a spare on the trailer.
Anyway being a dumper you can raise it even with a full load (unless it has a flat battery AND a flat tire AND a full load:thumbdown:).
And when you horse it around when full, the tires scrub hard on the ground, it seems a perfect way to cut a tire.

Seems strange there was none provided, considering what a big problem it would be, to have a flat while loaded.

I suppose these dump trailer mfrs have to compete hard on price at the lower end.

Nice job. I checked mine (Loadtrail 10k) it has a crossmember exactly in the way of where the tire would go. But it has a spare mounted on the side anyway.

Mine is side mounted also.

I might even splurge on a spare wheel and tire someday.

Certainly couldn’t do that with walking beam axles.
