Score another for airspring suspension in the back...

Had for a long time a bead breaker in the kit - one of those ones with two hooked feet that are pulled together via a long screw jack to lock into the rim, and another screw jack set 90º to push the bead off the rim. Tried it today on my Bruiser tyres - 285/75/16 - would not even look at it. I am not a small person but with all my strength I could not get any purchase on the rim to start the process (and yes I DID deflate the tyre first!).

So what to do? Read a thread somewhere where someone modified a bit of square steel to fit into the tow bar receiver, which had a cutout for a jack head, the base of which when operated broke the bead.

I like that idea and started thinking a bit more. I have airsprings in the back (full coil replacement, not inserts), height controlled by electro-air switches. I found myself a brick, put it under the tow bar and got the missus to lower the suspension.

And it worked!

So now to design something a little more scientific, mainly to protect the tyre and stop the brick bit from slipping (safety), something with a foot and top made from channel to lock it into the towbar...

Gotta ring me welder mate...

I just use the jack to replace the brick in your example. Have to be a bit careful with foot placement onto the tyre but I've used this method successfully. I don't have air springs but used the jack mechanism instead.

Yeah - something I have seen before. My concern was to stop the jack from slipping. And something that was quick and ready to use. Not sure about what damage a misplaced jack base would do to the tyre as well.

I have some Oregon, I think 100x100 - I might shape a length to act as a foot and put a notch in the top or something to hold it in place...

Watch this space :) - I'm on a roll!

Check out my post 70970, some pics of a jack beadbreaker, I just used a piece of 1 1/2" black steel waterpipe welded to a piece of 50 x50 x 3 mm wall rhs tube. Jacking down on the tyre is very controlled and smooth and doesnt leave damage marks on the tyre like the beadbreakers. I have used this method on my spare recently and the tyre had been on the rim for 4 years, too easy.!! The idea i originally saw on the LCool site put there by own own Phil G on this site.. Michael

Hi Viz

Glad you got it off .

Seen that both used sucessfully and unsucessfully.

Sometimes it pushes away from the rim and slips off.

I am sure with some thinking it could be made so that the force keeps it moving towards the rim.

I haven't yet not been able to get a tyre off with my Tyrepliers , but some have taken a bit off effort and stuffing around.

The real trick would be to help get the tyre fully off the rim.

In the meantime I make sure I break the bead on my tyres every so often just to be sure it isn't stuck when needed to be done.

viz,
You're a bloody good aussie bush bloke as my mate Stan is want to say.

That's his ultimate accolade for someone who can fix anything with nothing.

Just a thought, it might pay to look at doing both sides of the tyre simultaneously. See below,
