Edit: The rim in question is the Sun Ringle Rhyno Lite 26x2.00 with 36 holes.
Use two wraps of 1 mil Kapton totaling 0.005" versus 0.020" for typical rim tapes. 16mm (5/8") works well for traditional road rimes, 19mm (3/4") wide.
Combine that with proper technique, starting 180 degrees opposite from the valve, milking the slack around, and finishing at it.
Manufacturers make rims tighter than they used to, perhaps to reduce liability risk from a flat tire rolling off.
