Replacing a bad inner tube on a 21" rim.
What and how is the best way to use a spreader.
Should the hook at the end of the lead screw be placed across the split on the rim?
And the 2 pivoting arms be placed equidistant from the split?
Same positions when the spreader is used to close the rim?
Am a newbie and want to learn correctly. Thank you.
These images should help.
dont go too far !!! they bend to an egg shape. just get to the point that a tire iron is still needed a bit. use the same tool to push the rim back too. easy, peasy
