Zipp 303 NSW Carbon Disc Wheelset - Max Tire Width
I can't find anything to answer this question. I have the 303 NSWs that ARE NOT the saw tooth rim profile.
Can anybody tell me (or point me towards where I can find it) what the max tire width I can safely ride on these rims are?
Thanks!

Before the hand wringing starts - it's worth noting that the 303 NSW is an older Zipp wheel that his hooked and has an internal width of 19mm. It's also rim brake.

According to ETRTO, you can run 55mm tires on a 19mm rim.

Pretty darn wide (I think you have your answer above) but you have to watch the deflection at a certain point. I'd be fine running 44s on them. After that I'd be wary of how the tire may deflect on hard downhill corners. I have done this with 19-20mm rims and 44s. I prefer how they feel on my 25mm rims but I do not go over 44mm tires.

This is the road cycling forum, how wide of a tire do you need to accommodate? Maybe then just look for a yes/no answer.
