As for why wider tires for heavier riders, because they compress less at the same pressure, so you don't have to pump them rock hard to avoid pinchflatting.
Isn't it all relative? A 23 pumped to 140 psi will deflect (same tire drop) the same 15% as a 30mm tire pumped to 95psi. The same 'compressability' ?
