If you are interested in the idea of creating such a swing of automotive tires I propose to refer to the detailed photo master class for its manufacture.
First, choose the right tire. Pay attention to both sides and determine which side looks better. This will be the upper part. Using the drill bit, drill a hole. The most stable shape is a triangle, so make the holes in the form of it.
Prepare screws and washers as shown in picture. It should look like this after the fastening.
Next, take the S-hook and insert it into the eyelet of a bolt like this:
Using a pair of pliers we clamp the ends of the large hook, so that the chain does not get loosed. Repeat this procedure with all the hooks.
Further steps are as on the photo.
Tire swing is ready!
