Removel of tires from 41 Chev DND
 

Ok I'm a newbie at this, trying to get the tires off my Chev Portee.

They are deflated, all rim bolts off but the rims are rusted to the tyre, have parked a 4 wheel drive on the tyre to try and get pressure downwards, unfortunately they are the original 1941 tyres that I believe you can drive on after they have been puntured etc. They are as tough as Jiff,s nuts (so I have been led to belive!! ) Am now looking at driving a truck over them when I get one heavy enough. I know I am re inventing the wheel (excuse the pun)

ANY SUGGESTIONS

You can always try this method but if looks kind of iffy. I took some to the tire shop and they each took about a half hours beating with one of those chisel shaped bead busting hammers. They just kept hitting the tire right by the rim until it moved.

You are a gem. The hammering bit has been done using wood splitters etc. The local tyre company dont want to know. Love the picture, how do you guys come up with those I do note that everyone is standing at a safe distance

I used a Reciprocating Saw to cut the tyres of my old rim goes through the canvas backing pretty well once i got to the steel fibres in the edge i used a chiesel and hammer to bust through them . Worked a treat . :D

I ended up cutting pie shaped wedges out of the tyre with the back of a madick then cut the wires and bead with a 4" angle grinder.

Hi,

I have had the same problem.
For that reason I have make a tire remover and special
for 16" combat rims with 6 or 8 holes and also for 20" rims
with 8 holes !

Your tire removal machine is a thing of beauty
 

The only problem is that it is the only one I've seen and most of us can't just drop in to share a beer and as an incidental use the machine.

All jokes aside I've done this on several sets of tires now by hand and though I'd love to have Herman Van Hove's tool the best thing to do is take them to a heavy truck or tractor tire shop. Once they see that these are not "split rim design" you should have no problem getting them to put them on their power bead breaker and push the tires off. This is what I did on the last set and disposal charge for getting rid of the old tires was almost as much as charge for breaking the tires off. While your there ask them if they have an automated sandblaster for cleaning the rims. Several of the heavy truck places around us now have these units and for about $20 a rim they will bead blast them to nice clean steel. Once you have them clean paint them well and that should be the end of your problems getting tires off and on the CMP rims.

I have to agree with Phil.

I tried several methods and finally decided that if I needed an Apendectomy I wouldn't do it myself. So after my wife watching me have a near coronary she in all her wisdom said why don't you take them to the pros...

Now where's the fun in that? I found that hammering on old tires to be cathartic - a great way to beat out your frustrations. Besides, it motivates you to make sure that your rims are nicely cleaned and painted before you mount new rubber. Removing your own tires is also a great way to ensure a good nights sleep!

If you do see a pro, make sure they take care not to twist off any of your studs...

Scuze me, I gotta get back to bed...

The best thing for removing tires from an old rim is a heavy sledge and some tire wedges. The wedges are cut from some 3" angle iron about 5" long. Locate a couple of them so the edge is about to go under the lip of the rim and hammer away. Safety goggles are recommended, as is a hardhat in case the hammer hits rubber and comes back up at you.
Once the tire wedges are beat into shape, they work even better.
When I was in the army, I remember having a tractor trailer tire once in that we couldn't budge off the rim. We had fairly expensive machines (coats 5000HIT) for this type of job and the machine was starting to bend. So we sent it downtown, and a little guy with his hammer and wedges had it off in 10 minutes. That was after we struggled, to no avail, for much longer than that.

cathartic perhaps....
 

Every time 9er Domestic acknowledges my on-going affair with Olive Drab positively I jump at the opportunity to quickly agree and take her advice. Even if it may not quite be right.... :devil:

No harm in a little Phsy-Ops:smoker:

MANY MANY THANKS TO YOU ALL

AT THE MOMENT THERE IS A GUY USING A DIGGER FOR A COUNCIL PROJECT OUTSIDE OUR PLACE. I INTEND SEEING IF FOR A FEW BEERS WE MIGHT USE HIS HYDRO ARM TO BREAK THE BEAD , FAILING THAT THE CHAINS ARE IN PLACE (RE THE ORIGINAL PHOTO) AND ALSO A LOT OF GREASING TO THE AYOTTOLLAH (WIFE ) OVER EXPENSE TO ACTUALLY SPEND MONEY ON THE TRUCK AND TAKE THE TIRES TO THE PROS.

VERY GRATEFUL ALL FOR YOUR PROMPT RESPONSES I AM ACTUALLY HOPING TO PUT THE ORIGINALS BACK ON BUT I THINK THATS A PIPE DREAM

Just been through all this 2 weeks ago. Really the only option is go to a tyre seller who specialises in trucks, the local Beaurepairs I went to had this magnificent machine, bascically a 4-jaw chuck to hold the rim, and a hydraulic arm with a "plough disc" on the end of it. The older tyres will have had the bead fused (and do I mean FUSED ) to the rim, the disc is forced in to the bead seat while tyre is rotated. This is the work of about 1-2 minutes, per tyre. I meant to take a photo of the process, but by the time I remembered it was all over. $10.00 per tyre removed, about the same to leave the old ones behind. Without doubt a real bargain.
Have fun
Rich.

Last suggestions.....
 

....for those so incline to demonstrate their masculanity by pounding on a tire carcass..... at the pro tire shop..... before using any kind of machinery they always pour some old gasoline or kerosene/diesel or what ever is handy on the bead/rims junction..... according to them it softens the rubber and helps the release of the tire.

In response to Rookie's last post....... I have used the front edge of my tractor bucket and managed to repeatedly lift the front axle of the tractor off the ground and still could not move thetire bead down the rim...... in fact the tire casing would rip but the bead would not move.

I have 7 rims to work on and they are waiting to be delivered to the tire shop....... in by 8 out by 5.... no pain no blisters. As pointed out by Rob Clarke we do take the time to remove our own rim bolts so the tire shop will not break themoff withthe one inch air drive they use.

Just to add to the fun
 

You need to remember that some CMP rims with "run flat" tires were fitted with a solid bead lock, other words a steel or rubber spacer that completely fills the space between the to tire beads. This makes it impossible to slide the tire bead down away from the outer rim edge. Even some of the power bead breakers have trouble with these, because they are pushing against the two sides of the rim and there is no give. In these cases the it may be necessary to let the machine make several revolutions around the tire which tends to break the hold of the rust. Eventually the rim will start to walk out of the bead.

Thanks again guys, the initial event shall take place in 3 days with a lot of assistants. Its a reason for a few beers afterwards cos its so hot. Yes they are run flat tires, and I would like to keep them for sentimental reasons or give them to the army museum, thats why I dont want to destroy them. As it stands a local mechanic suggested the same as Phil and to to take them to an earthmoving firm (there is one down the road ) and crawl around them.

He also mentioned awesome pressures to remove this type of tire from a split rim Like 40 tonne (metric) However I shall report the results

Rookie

That picture of Phil's shows where the problems develop when you try ordinary bead breaking methods. You can't push the tire down to break the bead. You have to move the one half of the rim up. That's why the wedge shaped hammers work. The same applies for those motorized bead breakers that force the roller between the tire and the rim.

THANKS TO YOU ALL

MISSION ACCOMPLISHED TODAY. USED TREE WEDGES (NOT TWO JIFF) AND A BFH

ALL DONE

THANKS AGAIN PEOPLE

this works for me

next use 2 wedges to push the tyre

I use the long bar to clear the bead from the rim

for the last side I place the rim on a block of wood to knock the tyre off and then go and have a cuppa tea

Tyre removal science
 

Removed 10 60 year old tyres in couple of evenings a little while back using following method.

Lay rim on floor
pour kero on bid
pick up Hitachi electric jack hammer with a flat spade bit
stand on rim to prevent movement
start jack hammer with spade bit flat against rim
work around in half spade bit width takes about 10 minutes and bead is free.

Message for Rob.....
 

..... we now have two new options to remove tires.......some where in the barn I have two large wood splitter wedges...... worth an Aussie try....

....and I like the idea of the jack hammer........ will check on daily rental.


The Rotters are prepared to try out new approaches since our local tire dealer has indicated that his employees were spending to much time for what he was charging to unrim a tire......... from $10 to $20....... with 7 + rims to do a little experimentation is indicated......

Will take pictures of one of us bouncing the jack hammer on a tire.....

Jackhammers
 

Jackhamers are cheap in Australia since the invassion of low cost tools from China, you can buy a new unit for about $180. I have abused mine for a number of years with house extensions, post holes and tyres.

I will be doing five new removals in a couple of weeks to fit tyres for Corowa, I will get some photos of Jackhamer action.

Yes Pleeze......
 

....would love to see you bouncing around....

Thanks

tool rental...
 

Just checked to nite....rental cost of a Hilti electric breaker (AKA jackhammer) is $42 a day.... if I can do the 7 tires I will have saved $100....less the chiropractor fee...... bandages for blisters..... anf the horse liniment for my back

.....but the satisfaction priceless.....

And if there is extra time on the card, you can shave down the high spots on the barn floor. Beware of letting the kids loose on destructive toys.

Run Flats
 

I need to remove 4 run flat tyres from the Morris CS8 rims....

I will try the wedge and hammer method but I'm not too optimistic . :confused

Know anyone with a crane (grab) wagon??
The stabilizer legs make great bead breakers!
