(Granted this was an extreme example as the tire pressure (hot) on a kart is less than 12 psi. One would have to extremely wide to allow such low tire pressures on a conventional car.)

Valid point. If your tires & wheels are too wide it could be tough to get them up to the optimum operating temp on track, depending on how long your stints are, plus the extra drag and weight and whatnot, in which case you'll be slower. And unhappy. And poorer because you'll need to fix that stuff ASAP.
FML because I was that guy.
I once went through a very frustrating time with another car wondering why the 285s on 18x9.5s I was running were turning slower lap times than the 245s + 18x8.5s I had on it previously (R888s). All the signs were there in the tire wear and datalogs but by the time I figured out that wider =/= better it was too late.
