My bike before this one was a Specialized Rockhopper 29'er. It was my first one with such large wheels. Why, at six foot five, I never was steered towards large diameter wheels before that, I don't know. But it was Ben who recommended it to me. And ever since feeling the difference between that and whatever the standard size was (26, IIRC?) I was determined to always get the larger wheels, and I was very specific with Ben on this bike when I ordered it a few years ago that the wheels be the larger size. And the tubes seem to fit properly.
I'm a little embarrassed to admit this, but despite being an avid commuting cyclist ever since grade school, I am not super knowledgeable about bike maintenance. I have always gotten by relying on bike mechanics. I can tune things a bit, but I have never replaced anything other than a tube (I installed and programmed a few bike computers, before I realized - or admitted to myself - they were ultimately unnecessary for me), and don't necessarily know what to look for.
