Jared, our chief tyre inflator talks about what tyre sidewalls are. How it impacts on the performance of driving and what part of the tyre is considered the tyre sidewall.
Tyre sidewall is seen as the vertical section of tyre between the wheel and the tread pattern. The sidewall is visible when the tyre is mounted on a vehicle. More on that in the video.

- [James] Hey, Jared.
- Yo.
- Can you explain tyre sidewalls?
- I'm glad you asked that, James, sidewalls. So you've got the tyre. You've got the tyre here. Like this whole thing is a tyre, right? So a sidewall is this bit here. That's the sidewall of the tyre, and it encompasses everything from the bits that keep it onto the rim, all the way through to this transition here, right at the shoulders, into the actual tread face.
So the sidewall changes depending on the type of tyre. So, this sidewall, which is an SUV sidewall, is probably going to be a little bit more flexible. Ignore the plane, coming over the top. Whereas this sidewall is on a P Zero, and it's a whole bunch less flexible. It's also a whole bunch of rim protector in there as well. So that's going to offer you a less comfortable drive but you're going to get a whole bunch more performance, stiffer cornering, and that sort of stuff. Stiffer cornering? We'll roll with that, out of that.
But if you look at, say, even a bigger tyre, like this Kumho Mud Terrain, you can see how big the sidewall is in this, and so there's a whole bunch more rubber in that and hence, a whole bunch more weight. So that's sidewalls.
