|Brand spankin new tire install tricks please....?||curtybirdychopper|

|Last weekend I abused 4 tubes trying to install new michelin pro race tires. I am still pissed about it. In the process i ran out of tube patches.
The problem basically was i would almost finish the install, have about 4 or 5 inches of bead off the rim, and end up tearing the tub with my tire iron as i tried to lever the remaining bead onto the rim. the tube would get caught between the lever and the rim without fail, even as careful as i could be. there was so little room to stuff the tube into the rim b/c these tires are soooooo tight.
I figured out a small trick to that helped, once, to get me on the road. basically get to the point where 4 or 5 inches of bead are showing (and the tube isn't all the way inside the rim), then go back and take a few inches of bead back off the rim (thereby getting some slack in the bead yet keeping the tube inside the rim--key) and then stuff the remaing tube into the rim more easily with the additional slack.
Are there other common tips known to man and womankind that would help. The next time I flat out this new tire, I know its going to be murder so tips would help much.

|When I'm installing a tire, I like to put a little pressure in the tube. Then when I get to those last couple of inches, I let the air out. The tube tends to stay in the tire for me. One other thing that might help is really, really strong thumbs.|

|yeah, i tried keeping enough air in the tube till the end. The problem was that the first bead to go on wants to sit in the middle of the rim and not make enough room to share with the tube. so it was tough to get the tube to go away inside the rim.
now strong thumbs....that might be worth looking into. i can start hitchhiking, or playing nintendo, thumbwrestling, actually in asia its rude to point with index fingers so they pooint with thumbs the way clinton used to gesture when he spoke. i could move to thailand. that would be good.
i have no idea what kept me from throwing my wheel across the street hammer throw style, i was so angry.

|Keep it next to the furnace for a few hours-warm rubber is much more pliable than cold!|
|It is easy and you don't need tools...here's how||Dad Man Walking|

|Here is how I mount and dismount tires without tools, taking advantage of that "slack" that you discovered.
To dismount the tire, deflate the tube completely so that the bead is loose, then shove both beads into the middle of the wheel on one side while peeling both beads off in one direction on the other side. Once you get the hang of it, you can do it in the blink of an eye, by grabbing both beads opposite the valve and pulling up (to unseat the beads on the other side and pull them into the middle of the wheel), then over. Just like that, the tire and tube are off in one motion, while your buddy is still futzing around looking for tire irons in his saddle pack.
Reinstalling the tire, even a new one, is basically the opposite procedure, done in a few more steps:
(1) Partially inflate the tube (just enough to hold its shape, but not enough to increase its diameter larger than that of the tire).
(2) Stuff the tube into the tire (this can be a bit of a pain with a new folding tire, but it just takes time vs. any real skill). Make sure the valve stem lines up with the labels, or you will lose style points.
(3) Insert the stem into the wheel and get both beads pulled in tightly around the stem. I push the stem up into the tire and then push the beads deep into the wheel around the stem to do this.
(4) Begin prying the tire and tube onto the wheel. You will be shoving both beads over the same side of the wheel, and with any luck they will stay pinched together and rest in the bottom of the wheel, which gives you the slack you need to get the whole shebang pryed on with out tools. About 2/3 of the way around, you will need to open the valve and release pressure in the tube.
(5) It can get a bit tight at the very end...let out any air pressure that has built up, try shoving the beads with the heels of your palms instead of your thumbs, and, a last resort, grab a tire iron. Since you have seated the tube all of the way inside the tire by this point, you can safely pry the tire onto the wheel without pinching it between the bead and the rim.

|I wrenched for 3 years and while in the shop we learned a few tricks.
For a tight tire do as Dad Man Walking said but if you can't get the last 4 to 5 inches by hand then take your tire iron and go back beyond that last bit that needs to be rolled into the rim. Insert the iron straight down between the already seated bead and the rim. Then carefully (taking care not to slip and hurt your fingers) force the iron around the rim. That should do it. I have NEVER punctured a tube this way and you can even install Michelin tires on Sun rims this way.

|I almost always first mount the tire on the rim without the
tube, using tire levers; this seems to 'stretch' the bead just a bit allowing the tire to go on easier the second time
that you mount it with the tube. Also, using the heels of the palms of your hands to roll the tire up over the rim ,as the previous poster mentioned, is a good way of saving your thumbs. I recently purchased the Crank Bros.
Speed Lever, and it seems to work OK, again being careful
to not pinch the tube (although it's made of plastic, and
I'm just waiting for it to disintegrate on that one stubborn

|to avoid pinching,set it up so you can mount the part of the tire beside the air valve last. This way as you push the last bit of the tire onto the rim you can push the nozzle on the tube and it pushes the tube up into the tire and safely away from the rim.|| |
