    installing road tires

    I have been having difficulty installing road tires, mainly 27x1 1/4 tires. I will get the first side on all the way, then get the second side on all except for about a foot of rubber, which doesnt want to stretch up enough to get the bead over the rim. are there any tips/strategies to help this? I have never had trouble with mountain bike tires, just road.
    thanks in advance

    Road tires tend to be tougher to get onto rims than 26" stuff is. If you think 27x1-1/4 is tough, just wait until you try to mount certain 700x23 tires.

    I used to have this problem as well, but I learned ways to make it a lot easier. First of all, it sounds like you are doing the first part of the process right. If you can get one side of the tire mounted and most of the other side, then you have won half of the battle.

    Make sure you have all of the air out of the tube. If you are like me and put a snort of air into the tube before mounting it to help it hold shape, then you will need to get as much of this air back out as possible before mounting the last part of the tire. I like to press the wheel against the ground, squeeze with my knees, one hand, and my chin while holding the valve open with the free hand. This gets plenty of air out of the tire so that when you release the squeezed areas, the tube pulls away from the tire and is no longer a factor in the mounting problem.

    Next make sure that the bead opposite the last part to be mounted is not caught on the rim wall. 26" rims and tires are more forgiving in this regard, but road tires generally need some coaxing to get to the correct place. The rim has a deeper notch in the middle that you need to get the tire to drop down into in order to get the last part of the bead over the rim wall. I like to force the bead over the wall until there is some built-up tension, and then go around the other side of the wheel with my fingers to pop the bead down into the groove in the rim. You'll probably be able to feel some of the tension ease as the tire gets worked into the correct position.

    The last major trick is to make sure you are rolling the tire into the rim. The last bit of tire can be tricky, but it is pretty easy if you use this technique: Sit or kneel with the unmounted portion of the tire up and facing you. Grasp the wheel and tire like a steering wheel. Using your thumbs, press the bead of the ture up towards where it needs to be, starting from one edge and slowly working your way towards the middle. You should be able to use one thumb to lift the edge of the tire and the other to press it over the edge of the rim. If it gets difficult, pause and work around the tire again to make sure it is in the rim groove.

    Hope this helps.
    from Minneapolis, with bike love

    That is an excellent post. I would also suggest the use of a bit of talcum powder. Also, if still necessary, get as far as the OP said and leave it sit overnight. Should go on easier after a bit of time stretched out. The good news is that generally, subsequent mountings are a bit easier.

    Hi guys, I have been having a horrible time lately getting my 700cx23 tires on. I have blisters on my thumbs from fighting with them. I got them on, but now I have a flat, and am stuck, because i cant get it back on with the blisters. Is it really so bad to use the tire pry tool to pop the last bit on?

    I use my Pedro lever to pry that last bit of my 700x23 tires on all the time. I can't do it without using it. There is a pretty slick tool made by the folks at Kool Stop that helps with the last bit as well and is probably safer to use regarding pinching your tube than levering: http://www.jensonusa.com/store/produ...e.aspx?sc=FRGL

    I always leave just a bit of air in the tube. I don't think that it makes getting the last bit of tire over the rim more difficult, and what it does do is to give the tube a little bit of shape so you're less likely to pinch it between the tire & rim when mounting it.

    +1 on using a tire tool carefully when all else fails. As long as the tube is not pinched in there, it'll work without causing problems.

    Dish soap. I resort to the tire lever when all else fails (which it often does).

    I always use levers, you just have to be very careful with the tube.

    I think the first responder's tip about getting the tire bead at the opposite side of the rim (ie. 27 inches from where you are working) down into the spoke channel is very helpful. And also make sure the tube stem base is well inside the tire bead.

    +1 dish soap. i just replaced a conti gator and the last few inches are a b!th by hand. using a bit of liquid dish soap on the ends of the levers will keep them from catching and tearing up your bead/side wall - carefully slip the last bit onto the rim.

    When inflating after installation, I like to put a couple pumps in, remove the pumphead, and go all the way around the wheel squeezing the tire, kind of like rocking it back and forth across the rim, and rubbing it to and fro... Then I inflate the rest of the way. I found myself doing this after I pinched some tube in the tire bead long time ago and have been doing it since. Have never had that happen again. Seems to satisfy the tire seats properly and the valve stem comes out of the hole in the rim without being all angled and potentially stressed. Just a thought.
