You were doing well until here.
Friction is entirely independent of surface area. What you
have here is traction. Certainly you get more heat in the
side walls of a tyre that is underinflated though - it's
one of the biggest causes of blowouts in car tyres in fact.
All that flexing causes a lot of heat, try it with an
elastic band, stretch it fully a few times it should get a
little warmer.
