So this is how I take my tires off. Take the valve core off.
Take the lock nut off the valve stem.
Time to break the bead. Now this the part I'm proud of. I designed and build this bead breaker myself. I based it off the two internet ideas I saw. One used a huge lever and wedge attached to a wall stud and the other used a big hydraulic press from Harbor Freight. Both of those options were too big to mess with and use one a year or so on tires. So here it is.
Homemade 2x4 frame and wedge.
Now to the hydraulic part. A little bottle jack from Harbor Freight less than $20. (I carry this in my car to fix flats too.)
The first bead is easier than the second. I usually have to press against the rim on the opposite side to get it off, but it doesn't hurt anything.
Now the frame holds the wheel to get the tire. This helps when the wheels still have a brake rotor on them,
I use three irons. I really like the skinny one with the handle to run point. Then the other two hold things still so the tire doesn't jump back into the rim.
