    Mag wheel bead breaker

    I notice some members are having issues with bead breakers for their Alloy wheels. I faced the same delimma and made my own. I hope this post helps.

    The current set-up is for the Defender Alloys, but I also made a second one for the Series2 rims.

    I have tested this a fair bit and the concept works well. It is most important to always break the bead at the valve position first.

    A few pics paint a thousand words








    A good set of tyre levers is essential (This one is off a S2 Disco)


    Main part of the unit attached to the boat trailer, when yowing.



    Most repairs can be carried out with tyre plugs without breaking the bead - good emergency repairs, but for larger staked radial patches inside the tyre work well.

    The only downside is that the unit weighs 12kgs (without the tyre levers), but this is well less than half the weight of an additional spare

    not wanting to sound ignorant here but are there pics of a hi lift being used this way Zook? I think I have a pic in mind but a goodie here will confirm for me and a lot of others I'm sure.

    The hi lift works well on all the older style mags and steel disco / Defender wheels, and I have used this many times.

    The newer style alloy rims - Series2 Disco and later Defender alloys have a spiral safety lip at the inside of the rim, with the shallowest point at the valve stem. There is no way a hi lift will break the bead of these. I tried quite a few methods and the unit above works well - takes about 5 minutes to strip down a wheel. A rattle gun shortens the time.

    i dont have any pics......but all you do is position the base plate of the jack the same as the plate
    is positioned in the pics above........
    just next to the edge of the rim so it presses down on the tyre......

    and then jack up the vehicle......all you need to do is press the bead down far enough to break the seal.......

    Erich any chance of the picture of the rim without the tyre on (i.e. naked). I take it the boost rims are the same as the D2 alloys.

    From what I've been told Tyre-pliers can break the bead on the D2 rims if you know how, but I've never been shown.

    if your talking about the entire tyre plier unit that looks a bit like erichs set up then yes it can but you need to buy and adapter for it for the landrover mags for it to work
    Our Land Rover does not leak oil! it just marks its territory.......

    Sorry about the quality of the image - totally out of focus but you can see the lip. This is at the thickest point 180 degrees from the valve. This rim is off a 2006 TD5 Defender.



    One reason why tyre pliers are not so successful is because of the difficulty in getting a grip on the rim and the other is the chance of rim damage. I know people have succesfully used some specific tyre plier models.

    I was told by the inventor of TyrePliers that it didn't need an extension, just the correct technique for the LR alloys. They work fine on the steel rims.
