I would have enjoyed this but didn't understand it. I think the main problem is that I didn't understand what they meant by tyres "being flat" so the rest of it was impossible to grok.

The part of the tire that touches the road is flat as opposed to being curved.

  I think it's actually not - they mean the side face of the wheel, https://images-stag.jazelc.com/uploads/theautopian-m2en/cherokee_liberty-1536x639.jpg https://images-stag.jazelc.com/uploads/theautopian-m2en/cher... They're talking about the wheels, not the tyres.

  The newer tires also have the appearance of being flatter. This may be where the confusion is.

They that the face which you put the bolts through is flat. On older cars it was concave.

I didn't follow what they meant for a while either. This image helped: https://images-stag.jazelc.com/uploads/theautopian-m2en/cherokee_liberty.jpg https://images-stag.jazelc.com/uploads/theautopian-m2en/cher... It's not the tires that are flat, it's the face of the rims.

  Ohh. I thought at first it was talking about round, donut-shaped vs thin, cylindrical tires.

It's not about the tires, it's about the wheels (maybe calling them "rims" makes the connection). The parts of the suspension the wheel turns on are pushed out towards the center of the contact patch on newer cars to reduce the forces that feed back to the steering wheel. The different steering system used on older cars benefited from those larger forces (because the systems didn't have good feedback).

Well, they said the wheels are flat, not the tires.

It did fail to define some terms. Also, it would have been nice to show on the diagrams the direction of the forces involved. It's a bit difficult to visualize precisely.
