So we're wondering- what you guys are doing to change 'em yourselves?
Thanks- John
I'm sure there are lots of different ways. But what works for me is:
1. 8lb sledge hammer
1. 4 foot pry bar
1. 2 1/2 foot pry bar
Remove valve out of valve stem, lay tire flat, break bead with hammer, flip tire over break other bead. Then take smaller pry bar, tuck under bead, lift over rim, lay pry bar across the face of the rim while the end is still under bead. Stand on pry bar with one foot. Take second pry bar and insert it next to first bar under the bead, and lift bead up and over rim, and keep working around rim. Take small "bites" at first to get started, then as you get more of the tire over the rim you can move the pry bar farther down the rim. Once you get around half the tire over rim, the rest pops right over. Reach in with small prybar and grab the inner bead and repeat.
I can dismount all 4 of my 37s on 17inch rims this way in about 30 to 40 min.
To install, I take some hand soap, (currently I have a large jug of dial) put soap on your hand or a rag, and rub it all over the tire bead. The flop tire over rim, if it doesn't slip right over, place your knee on the bottom of the tire (the part closest to your body) making sure bead is under rim lip, then lean forward on tire, and press tire over rim (like doing a push up) repeat knee and "push up" to do the second bead.
To air up, I took a air valve used for airing up a tire, and removed the innards, so it is straight through "hollow" stand tire up, press down slightly on tire and air it up, pop the beads on, the install valve.
I can usually install and inflate the 4 tires in about 15 min.
This is just how I do it, I'm sure others have different and better ways, but it always works for me each and every time. And saves me a butt load of money not having a shop do it.
Oh, and as for the size of the bars, there's no particular reason for those sizes, they are just the bars I have, and I don't feel its necessary to go out and buy fancy "tire bars" if you take your time, and be patient a regular ol pry bar works just fine. I have probably done this at least 60 times and have never damaged a rim, bead or tire yet
