This explains how to build a tire swing. On the surface, a simple tire with a rope would seem to be a good tire swing. After all, it worked for us when we were children. But, these days, just tying a rope to a tire is not good enough. For purchased play sets, tires are now mounted horizontally instead of vertically, and that presents an entirely set of its own challenges. Here is how I succeeded in building my children a professional looking tire swing for half the cost!
Let me note at the onset that this instructable is not a joke. It is long and detailed, with lots of pictures. If you're really not interested in building a tire swing, then don't waste your time looking through it. But, if you are truly interested in building a tire swing, then this is serious and detailed instructions that ought to give you every tool to be successful. Good luck!
Step 1: Pick out a tire!
First, pick out a tire. Thinking that "Bigger is better" will only get you in trouble here. Without being indelicate, consider the size of the derrieres that will be riding the swing. For smaller children, a big tire just won't do. For large adults, a smaller tire should be fine - as long as it's bigger (the tire, not the derriere) than the one on your wheelbarrow! I was looking at a tire from a pickup truck, but realized our 2 1/2 year old twins wouldn't get near it. So, I settled for the tire I'd just taken off the 15" rear wheel of my motorcycle. Perfect!
Once the tire is chosen, look at both sides of it and determine which side looks better. This will be the top side. Flip the tire over and drill holes in the bottom sidewall. To do this, set the tire on a surface that will be at a height appropriate for drilling without straining your back. I used our new picnic table & it did the job perfectly. Use about a 1/2" drill bit and drill holes around the sidewall, ever few inches. The holes don't have to be perfectly spaced, but it'll drain better if the holes are more evenly spaced. I used the tread pattern to space the holes. Here's a picture of the bottom of the tire with the drain holes already drilled.
