Rear mounted spare tire anyone??

[jesusgatos]

If the tire support pivots and moves about 90 degrees (from vertical to horizontal), then you could use one ratcheting cable system or whatever to raise/lower the tire AND to raise/lower the tire support. Would need a larger drum and more wire, but something like the stock spare tire hoist would work just fine.

you'll need more than 90°...the tire has to touch the ground....~150-160°
depends on the height of the pivot point.

but with a little drawing and simulation it should be easy to determine the right points.

O.K. Guys, here we go again. A friend of mine ( wolfpack ) had the same problem for the same reason. He came up with a spare tire mount on the rear of his 109. The tire sits in a saddle and is secured to the rear of the vehicle and to the swing support. Under the vehicle you can pull a pin from the support pipe and pull the tire and mount rearward a few inches to a stop. Then the tire and swing assembly rotate to the left till it touches the ground. He had to give up the left rear door, but it was a good trade off. This vehicle is his storage and water truck, it has a complete bathroom and shower inside with a bunch of other stuff. Just behind the tire mount is his hot water system. I thought it came out quite well. I thought it may give you some ideas for you guys thinking along the same lines of thought. Anyway take a peek at the pics and see what you think. Happy Projects!

Thanks for posting up that variation.

Do I understand correctly that to lower the spare, you are at the mercy of Gravity? And to return a wheel to the storage position would require brute strength to reverse the lowering process?

Any thoughts on adding some mechanical advantage to that?

Thanks again.

This is an idea, this guy plans on using a rear winch and pulleys to lower his tire. If you mounted a swing away mount to the rear of the 109 and had two pulleys to rout a line through to lower it? Just a thought.

Check this out for other ideas.

No, what I'm suggesting is that it could pivot downwards about 90-degrees and then use something like the stock spare tire cable-operated hoist to raise/lower the spare. Make sense?

My thinking was the same, however he seems to have no problem with it. It must work much better than it looks like it would. I would think a small pully system or something would still be a good thing. Whatever, it gets the tire out of the way and on the back of the truck, and that is the idea, seems to do the trick!

the idea make sense, but why make things complicated? you need 2 hoists, on for swing, one for lift. with the correct connectionpoints and pivotpoint it should be easy to swing it to the ground. The advantag is, the tire stands in a most upright position, you havent't lift it from the ground. only roll it away....

just my 2 cents..

Agreed.
Keeping it in a "tread on the ground" configuration is a safety thing too - minimize your back injury risks.
