Agree I'm running IRC Mythos XC 700x42 on my CXP33 rims and haven't had any issues (rims are suppose to be 28-32mm max).
You may shorten the life of your rims a little depending on weight and tire pressure.
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
