Well, I guessed that bigger tires would mean less stress on rims than the smaller, higher-pressure tires they're made for... but, what about cornering stress? I'm guessing it's not an issue, either... but what do I know?
You might be too heavy to commute daily on those wheels. You may run into problems of breaking spokes and wheels coming out of true. Nothing catastrophic but annoyances that can make you late for work.
Either way, again, the wider tires will have absolutely nothing to do with it.
