Now, this is no ordinary bead. This seems to be super-bead. The story so far is that I bought 4 Land Rover wheels with 245/75/16 tyres on them with the intention of removing the tyres and putting them on my 16" Jeep wheels. I takes the first two to my local MOT/garage bloke, who struggles for a couple of days but then admits defeat. I then take them to another guy who's swapped tyres for me in the past, he struggles for about a week and succeeds in getting them swapped. Then I take the other pair to him, he has a go, tries what he did before and.... nothing, he just can't get the bead broken. He's maxxed his compressor out on the tyre machine trying to get them to go but nothing - the tyre shifts, but not enough to break the bead. So, remembering an old thread on here, I've made myself a bead breaker (basically a great long lever (8 feet or so) attached to a pivot on my garage wall. Then there is a piece attached a little further along the pole that will press down on the bead of the tyre and hopefully remove it. Nope! Still glad I've made it though, it'll be handy for changing my own tyres on other stuff.... Got no pics, but it follows this principle: So the question is (particularly aimed at people who change their own tyres), what do you do when you have a particularly stubborn bead? And can anyone recommend anywhere around Derby/Notts (preferably Ilkeston!) that maybe changes truck tyres?! Cheers, Martin

Go to ATS, they are a national 'truck' tyre supplier, i'm sure they'll sort you. The one nr here has (the last time i was there anyway) a huge pneumatic lorry tyre changing machine.

truck tyre was my first thought as well, however when I worked in Haulage we hardly had any tyre stubborn to come off the bead. this is all we ever used to use.

There are several ways to do this. I don't have any personal experience with any of the following methods, but they are based on traditional outback bush mechanic techniques.
First of all, get your 4wd parked on a hard, flat piece of ground. Slide the tyre under the front bumper so that you can place the foot of your jack on the edge of the tyre bead, and fit it to a jacking point. Then, attempt to jack up the 4wd on top of the tyre bead. If the weight of your 4wd will not break the bead, then you're in trouble! Traditionally, this is done with a high-lift jack, but it would also work with a bottle jack or scissor jack.
Here is the method, demonstrated by a Swedish dude. Ideally you want a heavier vehicle than a Suzuki!
Another method, if you happen to have a bare rim to fit your 4wd. Jack up one corner and bolt on the rim, then lower it down onto the tyre bead. This should work similar to the jacking method above.

Sadly I don't have a hi-lift, although I have tried the method using a little bottle jack under my Chevy Blazer (it's a touch heavier than a Suzuki ) to no avail. It's not got enough travel to pop it far enough off... Thinking about it though, I do have a nearby mate who may have a hi-lift, I'll give him a shout. Failing that, there is an ATS a mile up the road (that I'd never even noticed before!), I'll try them.

If you've got the bottle jack and the dead weight, then you should be able to make up the space in between using a piece of solid wood or heavy steel box section of the appropriate thickness. Obviously, when doing this be careful that it doesn't slip out.
Alternatively, if you can get the tyre loaded up and most of the way off, then a few swift whacks with a big hammer will usually shift the bead the rest of the way. It's easy to damage your tyre sidewall this way though, so probably not a good idea if you want to keep the tyres.

It's not the gap as such (I'm not that simple lol), it's the extension of the jack that's the problem - it'll only extend 6 inches or so, and given that some of that is lifting the Chevy upwards, it ain't enough.... And I do need to keep the tyres, so I'm trying my best not to damage them. Cheers for the ideas though

With really tricky ones, I use the front bucket of a tractor. A bit of wood between rim and floor to lift the rim up and allow the tyre to be pushed down beyond where the floor would normally limit its movement helps too.

It wouldn't be the first time I've driven our forklift over a tyre to crack the bead ;-) Also using a bigish car low pros can work but no good with tall tyres cos there's too much give in the sidewall.

My latest attempt didn't go so well, standing on the bar trying to break the bead has resulted in a slip, followed by a gashed arm and bruised (I hope! lol) ribs. Think I'll leave it for today now and try ATS tomorrow if I get chance....! If only I had a tractor.....

Have you tried laying the wheel on the ground and driving slowly over the tyre ? I'd say anywhere that has HGV's will be able to break the bead. That is hauliers workshop as well as ATS etc tyre depots.

I've tried most things mentioned (except the hiab and the lowering the car with a bare wheel rim), I think I'm gonna have to admit defeat and take it somewhere.... Which to be fair is what I tried in the first place, I just needed to take it somewhere a little 'manlier' in the tyre equipment area I guess.... lol

just done the same thing on 4x4 tyres,they would not break the bead on the machine, my solution was i drove to a field,new tyres deflated of course,then put them on the car and drove round the field slowly bead let go in 5 mins this was on a 74landrover that had the tyres on since new!!

leave it in front of a space eater for a half hour first, soft rubber moves so much easier than hard, i find doing anything with tyres this time of year can be a nightmare..

Yeah, I didn't think about heating them up... Ah well, I'll leave it to someone else now, my ribs hurt...
On another note, it turns out it's a day for doing silly things, I appear to have just bought an Alfa 156.... Pesky eBay!

Just as a quick aside from experiance running over wheels to break the bead a range rover classic is no good as a tyre changing machine, the V8 is too light, Isuzu trooper on the other hand works first time every time, Fergy tractor comes in somewhere between the 2.

Hydraulic log splitter. A piece of 3mm plate to cover back fixed support & some thick ply in front . Wheel against that & then use front ram with a piece of extremely hard 3"x3" or 4x4 right up against rim. Easier with two people as bit of juggling on your own.
