Best Rim Inner Width for XC

[Mikej]

There are plenty of aluminum offset rims.

I have 22ish internals on my XC bike, running 29x2.35. Works fine. I'm not sold on the necessity of width, especially as wider = heavier. I have 30 internals with my 650x48s on the gravel bike and they're nice but portly.

My 30mm internal width mtb wheels weigh about the same as my 25mm internal all road wheels. Both are below 1500 grams.

I prefer the wider 30mm on the mtb. When I upgraded to them from 25mm with the same tires they rolled smoother, quieter and had better traction.

Question before I make my decision. Would 2.25 tire be wider when mounted on 30mm inner comparing to 25mm? If so how much. I just want make sure there is enough clearance.
