Ideal Wheel Rim Width for 45-50MM Gravel Tires

  1. the tire is probably designed for a 21-25mm. The bigger rim will shape the tire wrong.

I think I disagree with this statement, shaping the tire could be better or worse

  1. The rim won’t be usable as a road rim or smaller tire rim if needed.

This is absolutely true, but OP is making it a dedicated gravel wheelset so that is not a very good point.

  1. weight (but those are light rims)

The rim weights are pretty dang close now, a road specific rim in a 24/30 in 44mm depth is 420g while a gravel specific rim that is 30/40 in 45mm depth is 450g. That’s 30g difference which really is not that much in a gravel discussion, tire choice will determine weight long before that is
