On a road bike, the maximum size tire you can use is usually limited by frame clearance. Do you have an owner's manual for the bike? If so, check it and see if it indicates tire clearance.

It's not altogether clear what the issue is otherwise. "Rough roads" in terms of chip seal leads to increased vibration, and larger tires will help, but it doesn't normally cause wheel problems. Bouncing off curbs or hitting major pot holes can do wheels in, but that would be partly a wheel issue and partly how you ride. Consider either using beefier wheels, or having a better wheel-builder do the work, and that would probably be a better solution that just upsizing tires.

I googled that bike up, and it looks like it may be on the low-end of the quality/cost scale, and that could be the issue with the wheels. On my bike, my original rear wheel lasted about 4,400 miles. The replacement is probably a little heavier, but has lasted about 10,000 miles now.
