If you have a flat tire on a bicycle, it’s no big deal to change it – mainly because almost all bike tires have inner tubes. But very little else around the house has an inner tube, so if you find a flat on your wheelbarrow, a two-wheel dolly or a small garden-tractor tire, you might well have yourself a head-scratcher. Look at the picture over there: the tire (blue) must form an airtight seal against the rim (#4, gray) or any air you pump into it just comes out around the edge, or bead, of the tire. If you want to pump air into that tire, you need to force the bead up against the rim - all the way around and on both sides.

It’s gonna take some ingenuity, but you can do it without taking the wheel to your local tire shop. All you need is a way to compress the tire. I usually use a band clamp, but for larger wheels a big ‘ol tie-down strap might be more in order. In a pinch, you can do the same thing with some rope and a stick, though you’ll probably need a helper for that method.
