Quick and Easy Method for Bead Breaking

Post by okie2ee » Sun Sep 09, 2018 10:32 pm



This is a method for breaking the bead on a motorcycle tire that is quick and easy and requires minimal physical effort. The key to this procedure is applying a concentrated force to the tire from a vertical direction. The force is the weight on the front tire of a car which typically ranges around 2000 lbs more or less. This force is applied thru a 2x4 placed on top of the tire and then driving the car front tire on top of the 2x4 until the front tire reaches the end of the 2x4 or the bead breaks. The bead breaking can be sensed when the front of the car drops a little while driving up on the 2x4.


This pictures shows the arrangement of the 2x4 on the motorcycle tire and the placement with respect to the front tire of the car. A piece of 1x4 has been placed under the rim to stabilize it as the weight is applied to the tire. A mat should be placed under the wheel to protect it from any scratching resulting from the wheel moving a little. I did not have any damage to my wheels due to movement. I broke both beads within 10 minutes. One side broke completely free and the other side required a little bit of prying to break completely free all the way around the tire. Obviously, care should be taken to not drive on top of the wheel to prevent any damage to the brake disk or the wheel.
I'm a new Goldwing 1500 owner and I really appreciate the vast amount of great info on this site, thank you for all the help.

that works pretty well most of the time,

but I think you have your "amount of force" calculated a bit heavy.

that car, at most weighs 3,000 lbs? / 4 wheels, = 750 lbs per wheel?
assuming equal weight distribution per wheel.

did you have any trouble with the wheel scooting away from the board as you drove up on it?

I use a long lever ... pole or pipe which attaches to post in basement, has a piece curved to set on bead that swings in one of several holes to adjust, I can get about 10:1 leverage.

Dad taught me that years ago. I usually place the wheel on a sheet of plywood rather directly on the ground. I always use a 4x6 piece of blocking as my drive up ramp. Much steadier and solid.

I did not have a problem with the tire moving around. It did slightly tip upward on the side opposite the 2x4. Also the force calculation was off, more like 1000 lbs.

After the beads are broke(assuming you don't want to keep the tire)I used a knife and cut the sidewall halfway between the bead and tread...all the way around...
I then pulled the tire and the cut off bead off the rim by hand.No need to pry on that hard rubber.Another 10 minutes.

Wish I would have thought of cutting the sidewall, that would have saved the extra effort to get the old hard rubber tire off the rim. I hope I can remember that for the next tire change. Thanks
