How to get the last 10th of my new tire on

Rehabbing the 27" wheels on my miyata 710. Rim tape and new tubes went in just fine. However, when installing a brand new set of vittoria zaffiro tires, I just could not get the last 10th of the second bead to go into the rim well. It takes a lot of force just to push it a bit in, and it seems like an impossible task without breaking something. Even better, as long as I got a bit in on one side, some tire slip out on the other end.

The tires are 27x1-1/8, so the size matches. I also watched videos online, and this guy explained that the bead is the inflexible part, I tried push the tire in but didnt help that much. Everyone else in the videos did it with so little effort (seemingly) that I want to swear. also everyone advised against using a tire iron to help with this.

Any tips? TIA.

Deflate tube completely. Finish the mounting at the valve. Go by very small steps and squeeze together the already mounted beads (esp. opposite the area you're working at) between steps. If still too hard, try a thinner rim strip.

As you work on one bead, you can use a toe strap (zip tie, whatever) cinched around the other bead to keep it in place so it doesn't want to start creeping off.

Do make sure you push the tire bead into the center of the rim like the above poster said. Sheldon: As you install the second edge of the tire, try to push it toward the middle of the rim channel, where the channel is deepest. This will give you more slack.

A little talc on the beads is supposedly helpful to let them slip just a bit easier.

Some people mount the tire on without the tube first just to get the tire to "stretch" and loosen up a bit before they do it for real. Others leave the tire out in the sun for a couple hours so it's warmer and more pliable to work with.

And watch what this old dude does on this tire, he's got skillz:

I have one Marathon left and when it dies I won't do it again. This is the hardest tire to install I have ever had. I use this. http://www.biketoolsetc.com/index.cg...&item_id=KS-TJ

+1, arthritis forces me to have several of these with the handles shortened a inch or so to fit in my bags or I need to ask for help out on the road.

There is also the tire lever made by VAR that will fit in a seat bag that makes tough tires easy to install; see:http://www.cyclebasket.com/m5b0s281p...l_Tyre_Levers_ I think there is a US source but not sure where; some LBS's can order them too.

I have an 88 712 those 710's are really nice bikes, probably the best steel frame ever made until Columbus copied Miyata's splined tubing concept.

Anyway, make sure you squeeze in the sidewalls toward the center of the rim first then try to pop the bead back on, do not deflate the tire, it's actually a little easier is the tube is just beginning to take shape. See this: http://www.youtube.com/watch?feature...&v=-XUFVrl0UT4 Notice the straps? This is old school but it works. You can also take a dab of hand soap and rub it onto the bead and that will aid it into slipping on. Always keep in eye on the tube as the man does in the video to keep it from getting pinch.

Some rims use the wrong width of rim strip, if the rim strip is too wide for the rim's needs then that will make it more difficult to install a tire.

I recently replaced the tires on my wife's bike with new Vittoria 700c clinchers. I had some issues as well with one of them until I deflated the inner tube.

thanks everyone. that old man has got the skills indeed. I watched his video for quite a few times, tried the tips he provided (deflate tube, push in side walls), but still I couldn't get it on....in the end, I went to a LBS and paid for some helpl. Let's hope the tire will stretch and bend before my first flat.

but now the tire saver is rubbing my tire! gotta go get rid of those now.

You don't need to get rid of the tire saver, you simply bend it a bit so that it just barely rubs the tire.

I wish I could have been at your place to show you how to get the tire on, but obviously logistics prevent such a thing, but you need to learn how to do it because if you get a flat you'll be back in the same boat if those tires are wire beaded.

In the meantime buy yourself that VAR tire lever mentioned earlier; see:http://www.cyclebasket.com/products....3s281p92&rs=gb Yes this is in the UK but the American contact, Retrogression, is out of stock on them. Also get a set of Soma Steel Core tire levers. Both of those tools are cheap and strong.

True but one mistake. It's much easier to mount a tire if one ends at or near the valve stem, as one cannot push the tire into the center of the rim well at the stem.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

+2......on both the tire and the tool comments. Hardest tire installation by far in my personal experience,
with much colorful language. Were it not for the bead jack, those tires would never have been ridden.
