I've had really good luck with leaving just a little bit of air in the tire, then breaking the inside bead first.... then, the outside bead.

 

I just take them to the local tire shop and have them pop them off the bead

 

Air it up and that will keep the sidewall from rolling. Stay back when it finally breaks!

 

thats sucks i just bought some 00 stock ds rims to put my mud tires on and i cant get the bead to stay

 

I finally broke the bead this morning...I had to dremmel through several layers of steel cords and then use a screwdriver to chisel the rubber up in one spot. Then my HF tire changer popped the bead and the tire took a whole 23 seconds to remove.

If you want the bead to stay, clean the rim and the tire really well - remove the valve stem, then spray some windex at the bead (all the way around) and inflate to 40-50 PSI with a hefty compressor (One that has a reasonable tank). You will hear the beads "pop" when they are properly in place. As a safety measure, do not go above 50 psi and be sure to keep your face and any valued body parts VERY far away.

P.S. I did try adding a little air and breaking the bead that way, too. The sidewall just kept giving in. I only used a couple psi, maybe that wasn't enough.

 

its good to see that you got that stubern azz tire off.
as for my tires i had the big o near me do it(3 times already) and i even paid 20$ but the one rim and tire wont seat they've even done some grinding on it but i think it might just be junk.

 

The best way to break beads on ATV tires when they are tough is to put a little air back in them. This way what you are using won't slide off the sidewall. We do this almost all the time. I own and Run a Goodyear Tire shop, ATV tires - speciallity the DS ones with the fake bead lock can be nasty.
