Hi All, I am mounting an Avon Storm 180/55 17 on a R1200RT BMW rear wheel. I am applying enough force to spin the tire on the wheel even with a helper. I am using plenty of lube and a tire spoon to keep the tire from spinning on the wheel to no avail. I’m trying to be patient as I am sure there must be a technique you can suggest. Thank you for the help! Gregory Clark

Greg, Be sure to lube the "Inside of the tire where the tire is pulling over the rim between 10:00 and 2:00 About where your bar is probably getting stuck. There is never "That much rotational force" required when using the correct technique. The wheel can slip if you rely on the clamps to prevent rotation. If you actually had the sort of tire that absolutely would not go on with the Mount/Demount bar then switch tools and us the SpoonBars to put it on. Your wheel tire combo does not justify SpoonBars. Be certain you have the "Handle" attached to the Mount/Demount bar WHERE WE SHOW IT. Without it, it will not work that well. The handle is for your "Right" hand and is PULLED. The bar is PUSHED with your left hip. It is rotated "Clockwise". Your left hand should be COLLAPSING the tire ahead of your hip and behind the head of the bar. Lube paste, generously applied to the "Drop Center" of the rim and INSIDE the tire where it pulls over the outer edge of the rim, before you begin tire installation, is essential. The other main thing to watch is the position of the "Valve stem" Removal should be about 8:00 and installation should be about 2:00. The stem can make a big difference on some wheels. It prevents the tire from slipping deep into the drop center reducing the clearance it takes to pull over the rim. You will not stretch the tire. The cable in the bead area is nearly 1/4" dia or more. Some tires really fold under alot for clearance. That is why the lube on the rim is so important. THE POSITION OF YOUR LEFT HAND COLLAPSING THE TIRE PREVENTS THE TIRE FROM ROTATING to a certain degree. If you are trying to use an "Xtra hand Clamp" to prevent the tire from creeping behind the bar for the installation of the last half of the tire. That may be the problem. Our "Yellow thing" tool does not push the tire down too far and allows the M/D bar to pass over it without mis-tracking. I have seen photos of someone's bound up tire with the black clamp installed. They remove the clamp and the tire goes on. I am not able to see what you are doing, but I know there is some simple solution , probably one I have noted. I know the tire will go on with one person without too much effort if all techniques described above are completed. We install them periodically. Let me know how it goes.
