This is on a 32 hole radial spoked Velocity Razor rim, Dura Ace hub ISO 406 wheel that I must have been an upgrade on the used Haluzak Horizon I bought last fall. The tape was actually fine with the original (worn out) 20x1.5 Primo Comet tire at ~80psi and the 20x1.5 Vittoria Randonneur I replaced it with. That was too heavy, so I had to go & put a Schwalbe Kojak 20x1.35 tire on there & 95 psi actually got me 20 or 30 miles before the spoke hole cut the inner tube.
I third the nomination of Velox rim tape. However, it's thick, which can cause problems when mounting very narrow 20" tires (if you wanted to try a Schwalbe Durano, for instance). In that case, I'de try a couple layers of fiberglass-reinforced packing tape. You can find 1/2" width packing tape sometimes- this fits narrow rims perfectly. However, it does fatigue and crack if you don't use several layers, and then the tube blows into the rim.
