planning a wheelbuild and I’m not sure what is the ideal range for internal rim width given my tire choice and type of riding.

Tires are Panaracer Gravel King SK 27.5 x 1.9”. Will be running them tubeless at lower pressure. Disc brake with 12mm thru axles. On a bike used for mixed surface rides, with a focus on gravel (gravel is relatively small, roads have some small pot holes).
