I guess it depends on how you use your bike and how chill a human you are. Me, I tend to be less chill about things like that. It shouldn't happen on a bike that's supposedly spec'd for tires that big (or quite frankly, any properly designed bike). If it's just a matter of spacers not being installed on the cassette then that's an easy fix. I wouldn't be opposed to 1mm to 1.5mm spacers on a BB shell either .. or flat out changing the BB spindle length. But otherwise no. I could not stand for chain rub on a tire ... even in a lightly used gear.
