This works for me:
Pedros levers
Tesa tape off eBay (get the right width for you rim)
Isopropyl alcohol
Wet and Dry paper
Clean the rims with IPA and lightly rub with IPA wetted wet & dry
2 wraps of Tesa tape on the clean rims (pulling taut)
Fit valves
Bit of soapy water on the tyre bead
Double check tyre logos aligned to valves (this is critical ;-)
Pump up the tyre till the bead pops onto the rim (check all the way around rim)
Deflate – add Stan’s sealant – reinflate and swoosh sealant around
Worked for me on multiple rims & tyres – always used Maxxis DHR or high roller or Spesh Butcher or purgatory (tubeless ready always)
For ease of use though the Stans rim strips are hard to beat and save the tape faff
