Tire changing instructions
Oh my. I don't even remember when I lost my tire virginity. And they say you never forget the first time!
I use heavy duty tubes that have slime inside & don't care about the added weight. At any given time during the month, I may have added or lost that much weight on my body! However, those tubes can be a pain to put in, so I keep regular tubes for road use.
Here are some tips:
Taking the tire off: Use your tire tools to get the edge of the tire flipped over the rim. When you get a good 3-4" of tire off of the rim, you should be able to use a tire tool to flip the rest off (put it between the tire & rim & run it around the tire). Don't take the tire all the way off - leave one side in the rim.
Remove the tube. Look for the hole. Cuss & throw away the tube (that's my story - you may be able to find the hole.) Note - I always pack my old tubes back & throw them away at home.
OK, here's the good stuff.
When you buy a new tube, take it out of the box & rub it lightly with cornstarch - sort of drizzle it between the folds. Now, put it in a baggie & put it in your seat pack. Now the tube just slides in the rim rather than sticking (and possibly sticking between your rim & tire causing the dreaded "snake bites." More about that later)
You have your tire halfway off (one edge of the tire is still in the rim.) Put a little air in the tube - just enough to give it some shape. You might be able to just blow some air in with your lungs. Put the valve in the hole & work the tube around in the rim. It may fall out, that's OK. Do the best you can.
Now - without tire tools - start to flip the tire back under the rim using your hands. Tire tools may pinch & puncture your tube, so hands are important. Get the part of the tire that is next to the valve in first - that's the hardest part. Move around the tire being careful to not catch the tube (which has a little air in it to give it shape) between the tire & rim. The last part may be difficult - that's why practice is good.
This is where you insure against snake bites. Inflate the tire just a little so that it is semi-hard but still soft enough that you can push the sidewall in & see the bottom of your rim. Push that side wall in all the way around, both sides, making sure that the tube isn't caught between the rim & tire.
You're done. Inflate the tire, get it on the bike & ride like the wind!
Flat on Bake Tire, ofcourse
So I'm all ready to ride on my trainer, while watching the Laker game, dilly dallied a little bit. Went to go get my bike in garage and rats! Back tire flat. We have an air compressor, so I fill the tire to try to find the hole, hear the hissing, can't find the hole.
Went out and bought a bike rack, yes I don't have one. I have one now. Plan to go home on my lunch today, pick up bike, go to bike shop and discuss tire changing. I have nothing. No spare tubes, no repair kits, nothing. Guess what I'm buying.
Why is it always the back tire? It seemsthat I've had 4 flats in the back tire, in the last 4 months!
Can't get the last 8 inches on the rim!
My boyfriend helped me change my first flat at home over the weekend and I rode the same trail again tonight and got a thorn in the tire again. (Front tire, luckily) Managed to ride it back to the car and brought it home to change and patch. All went pretty well until trying to get the last 8 inches of the tire back on the rim (knobby mtb tire). I just can't seem to be able to push the @#^$ thing in! Any tricks? I have a little arthritis in my thumbs and not a lot of hand strength. Help!!
