Finally got all of the tools in place to do my first tire change (Mojolever, Parnes balancer, harborfreight assembly). Ran smack into a problem. How the heck do you break the bead to remove begin the process?!?!? Air out, valve core is out, but I can not seem to get the tires to squeeze down into the wheel "valley". Old Mich Pilot Road II seem awfully stiff. Is there a trick??? Started to use the bead breaker on the harbor freight stand, but ended up leaving red paint on the wheel. Crap. Tried a couple clamps, but could not exert enough pressure.

Any advice would be appreciated. Lots of lube to get this part of the process done?

Guess I should have paid closer attention during all of those tech daze...... Seems like I do remember someone cutting their tire off once....

A large vise works well.

I remember a gallon of blue tire lube you had at a previous tech daze; in particular, I remember it not being very lubricative. If you're still using that stuff, I'd recommend pouring it in your neighbor's yard and starting over with a blend of dish soap and water, with significant amounts of dish soap. Alternative would be RU-GLYDE, available from NAPA.

What I've found helpful in the past:

-use the bead breaker to open up a small gap between tire bead and rim.

-squirt lube into that gap.

-release the pressure on the bead breaker, letting the tire bead spring back up; my hope and suspicion is that this squishes the lube around to areas otherwise inaccessible.

-It should now be a little easier to break the bead.

Some tires are more stubborn than others. No matter what, protect both sides of the rim with a few layers of shop rags when using the bead breaker. You might have luck removing the red paint with some polishing compound after the tire change is done.

I've never had to use lube to get the bead broken. (It seems like a good idea, though.) Usually I just go around the tire a few times with the bead breaker...applying pressure every few inches. Eventually it comes loose.

The bead breaker will get the job done and the red paint will come off. Don't get in a hurry, and keep turning the tire. I also put a towel or some other type of protection on the underside of the bead breaker.

Techniques tried in Mexico.......Large C-clamp....... or....
2x4's on either side of tire to protect wheel and run the car over it.

Now, when you can't reseat the tire, like on large sand tires or truck tires, I've seen Mexicans pour a little gas on the inside of the tire and light it. POP!!!! the tire is seated.

These are desperate measures, be careful. But they work.

I think the big red steel thingy assembly is the first problem.

Personally, I use a 2T floor jack with the rim/tire assembly positioned under a vehicle (truck w/some ground clearance), 2X4 used as backing to protect the rim against the vehicle frame.

Position the foot of the jack at the bead/rim, jack up till bead breaks, release, flip over, rotate 180^, break the other side. Tire Irons to peel tire from rim, done.

OK! Tire off. Just needed a little more patience, and a whole lot of lube. Covered the part of the bead breaker on the bottom (that can come in contact with the wheel) with a piece of self-adhesive UMHW. Kept going back at it, adding more lube, and presto! Was a fair amount of rubber stuck on the inside of bead seat and rim lip, so I can see why it was sticking.

I about died laughing reading the gasoline seating technique....

Now comes the fun part, putting the new one on, seating it, and balancing.

Thanks for your help guys (as usual)... Good to hear from ya Mitch. Been a while. Any Tech Daze in MI area?

+1. There is a nice gentleman in Missouri that makes a machine that has no problem breaking the bead, removing and reinstalling the tire, and wont scratch rims either. Gouge one wheel with some lash-up and you have spent more than the very reasonable price he charges wink

Just sayin..
