That is not entirely true. It is important to note that most high performance summer tires and most R compound tires do run much wider than "advertised". A 265mm tire on a 9" wheel can bulge quite a bit and is not ideal, a 265mm tire will fit much better on a 9.5" wheel. The same can be said for a 10" wheel with an aggressive 285mm tire.
If the tire brand and compound are on the aggressive side, fitment and performance would be impacted when compared to running the extra 0.5" of wheel width to give that extra bit of sidewall support.
