The one problem I would run in to is the jack sliding off the bead due to the angle, which I think you have found with the lumber. What if you tried whacking it with a sledge or spud bar after you put some weight on it from the VW? use of alot of soap helps.
I now use the bucket on my tractor if I have to change one, but i still keep the old bumper jack.
Good Luck and drink lots of fluids!
I have broken a bead before driving up a plank of wood with a heavier vehicle. I don't know if Kerry was pulling my leg with the HF tire irons as a bead breaker. I want to see a video of him doing it. Wacking it with a sledge is asking to hurt yourself I think. That steel belt on the bead that I cut through with the Sawzall is a bit over 1/4" diameter! It's a tough S.O.B.

I haven't tried breaking the bead with the HF tire irons ( though I have some), but the HF manual tire mounter works well for this. I have had one for maybe 5 years and have easily paid off the initial investment ( and have the bubble balancer as well). The harder part is getting the tire back on the rim (takes quite a bit of force to push the bead on w/o harming yourself) and that's where the tire irons help.

Do you have plastic coated irons to protect alloy rims? Bubble balancer eh? Is it any good?

Has anyone tried drawing a vacuum in the tire to break the bead? I'm gonna give that a shot.

You know about vacuum pumps right???

Maybe the vacuum with help from the tire irons or sledge hammer will make a difficult job easier?

No- I haven't tried any alloys that I really care about.

Good enough for me, so far. But I drive slow and I suppose if you find a rim that is bent, a dynamic balancer is much better. But I like having full control of the process and I don't like being told I can't do something.

I guess it would help but I don't know of many vacuum pumps that can suck more than one negative atmosphere - that's about 14 PSI (and pretty good going) - is that enough to break the bead? I don't know - it could be - it might not - like I said you need some good lungs!

As a point of interest our (OM617) vacuum pumps are meant to be good at 10-15mm hg (right?) that's about 0.2 PSI if I've got my conversions correct.

Atmosphere (unit) - Wikipedia, the free encyclopedia

Indeed - a healthy attitude when it comes to car mechanics (and possibly other things in life too!)

OTOH, sometimes it turns out to be wise advice...I have a lot of junk laying around, as SWMBO points out on MANY occasions.

average OM6xx vacuum pumps pull 22inches, and they can reach 26 or so...
I wonder what the max vacuum they can draw is...
I've got several reclaimers, and recovery machines, also several dedicated vacuum pumps capable of 25 MICRONS (that's 29.99999 or something like that inches of mercury...) anyway, 15" mercury would be about -7psia

Indeed, -1 atm is about the maximum unless you're going to put the tire under water.

No one has stepped up and said they tried using vacuum to help break the bead. When I suggested using a Sawzall to cut the bead, I was told it would not work. I am glad I went ahead and tried it anyway and found that it does work! When I get some time, I will try vacuum and report my results. If any of you are curious enough and want to try it before I get to it, feel free to do so eh.

Yep sorry - I'm not trying to pee on bonfires - give it a go - we need trail blazers here...

...I'm just saying you'll probably need a lot of suck that's all.

If you can get one of vstech's -7PSI pumps - holy moly you could probably turn a cow inside out with that!

Heres a pictorial...

Or you can repurpose a log splitter to break the beads.
