    You can spend the bucks and mount a tire changer to the floor taking up valuable space, or just grab a few short lengths of 2x4 and a 2x6 about 5 feet long. This is all you need for breaking your tire bead.
    First thing to do is remove the valve stem​

    Next set up the wheel so the brake rotor is protected from hitting the ground.​

    Stand next to the wheel and jump onto the 2x6 close to the tire. Use a little follow through and you can easily achieve the desired result. Flip the wheel over and break the other side loose the same way.​

    For rim protectors,I have had the best results using two rubber sheets that are 1/8" thick ,4 wide and 10 long. I insert the sheet between the wheel and tire iron. The large surface allows the iron some leeway in movement with no fear of marring the wheel.​

    Start (and Finnish) prying with the irons at the part of the tire farthest from you , using your knees to hold the tire closest to you in the middle of the rim. Use lots of soapy water to help. ​

    Getting the second bead over the rim is tricky. I usually use 1 iron and a knee to peel the tire off. ​

    When installing the new tire , the first bead will pop on with no tools , just soapy water. The better job you do keeping the tire closest to you in the rim "valley" , the less force it will take to pry the last bead on. Leaving the tires sit in the sun prior to starting makes it essayer too. ​
    I Finnish up using a home made balancer setup. ALWAYS use a torque wrench on your wheel studs and brake calipers. [​IMG] [​IMG]

    I use a big C clamp and a couple small pieces of lexan. I carry these under the seat.

    I use the kickstand.

    Well, if there's a spare one available.

    Thanks for posting and good job fabricating the balancer. BTW, that old Tourance looks like it still has some miles left on it...said the cheap bastard. :D wayne

    <BR>Nice post, bemiiten. Thanks. I have ALWAYS wanted to know if breaking the bead with a piece of timber like that would work. Cool Pennytech.

    Same beadbreaker I use, works well too. I cut up plastic laundry detergent bottles for rim protectors. You can cut any size you need.

    thanks for the write up and pics bemitten - I also have used my car to drive over the tire to break the bead.

    This method even works with the rear 950adv tire! :thumb :thumb :thumb

    Ever since I started to use this method to break the bead,
    I`ve been changing tires simply for the fun of it...
    it`s almost as good as my brother`s big`ol GS kickstand! :lol3

    I recently put some 400 miles on a tire that looked just like that - that took it down to the point where a different compound of rubber was showing in places, and then I had it changed. The mechanic that did it made a point to show me how little tire was left - it was quite alarming - one sharp rock would have had me on the side of the road. My comfort level was passed, and I won't do that again, unless I'm real close to home. ( the wilds of BC are a long way from home )

    so are you telling me that the bmw wire wheels are tubeless?:eek1

    well if that dont beat all.

    seriously, i am looking at buying a GSAdventure and i thought 'dam it has wire wheels, you would think tubeless would be the way to go?'

    well i learned something new tonight.

    the spoked wheels are an option and are supposed to be stronger than the cast wheels.

    Look at where the spokes attach, as compared with a normal spoked offroad rim. That's how they do it. Quite clever, they should have put the wheel guys in charge of final drives.

    :lol3

    BTW, breaking the bead can be incredibly stubborn on rear tires, I had one the last time around, using the 2x4 and a small board method that lifted the entire rear end of an SUV up in the air without separating the bead. It broke 1 2x4, but some weight in the vehicle (my friends) and a 2x4 instead and it finally gave way. Nothing made for road-side bead breaking would have done it, no way.
