Anyone know the best way to break a bead on wheels?


I'm trying to break the bead on a couple wheels to throw some tubes in them and I'm having a hell of a time. Anyone got any pointers? I've done it before, but I did it by stacking a wheel with no tire under the one I was removing the tire from. I don't have that luxury this time. I left my spare rim at home.

IF they are standard buggy tires, usually you can just let the air out of them, lay them flat on the ground and stand on the tire, work your feet around it a little and it will break the bead. I have never had one that I couldn't do that way except the custom aluminum ones, those I take to a tire shop.

They are standard Peter Lynn wheels with extra wide tires. I've been trying the trick with my feet but no dice for the past 30 minutes of trying.

I use Kent's method too. The other day I had tires with dried tire slime on the beads. I added the help of a proper tire iron to help pry the bead a bit at a time going around. I am off island at the moment but will be back soon and I have the tire iron and a spare rim. Holler if you need it. 912 577 3920. I also have extra swear words.

Bingo! I danced on it some more after soaking the bead with soapy water and it finally let go. Now the question is who brought a spare extra wide tube with them because I brought only one in my bag by mistake.

To add to the laying the rim on its side, I usually find something similar diameter to put under it to give a little clearance so that you can use more force to break the bead

I have used a couple 2x6 blocks with corners trimmed to make them semi round under the rim.
Works even better with a long carriage bolt bolting them to the rim. Makes it more stable to stand on.
With BF lites on barrow rims it gets trickier.

I finally got the Harbor freight mini tire changer.

Use the ever present 20% coupon to get it for less.

Makes conversion from barrows to midis to BF lites so much easier.

Plenty of soapy water and the trick is not to let all the air out of the tyre.
Let it down to only 1 or 2 PSI and this holds the shape in the tyre while you work on the top bead. The end of a bit of wood whacked with a hammer right in close to the rim usually pops them off (work around about only a quarter of the rim).

The inflated tyre allows the pressure to be applied right where its needed rather than slipping off away from the rim/bead area.
When it pops off reinflate with a lubed rim and let down again to 2 psi and remove the last bead. The previously broken bead will then slip off easily as it has been lubed up.

This works a treat with the Sysmic rims getting the tyres over the safety bead built into the alloy rim without marking the clear coat.
