Other types of racing, such as Formula 1, hardly any flexure there.

You haven't seen F1 drivers have a warm-up lap before the race,
deliberately snaking side-to-side?
Here's a better example. Go outside and feel the tyres on an
ordinary car that has recently been driven for a mile or more.
They'll be warm. They are only flat at the bottom, though.


Yes, but they aren't building heat up in those tires by flexure during
those maneuvers. They are simply loading each side of tires down on the
road. There is a bit of flex, for sure, but the majority of the heat
comes from road friction.
