I’ve been refining my technique for putting on tubeless tyres. If you’ve never tried and are thinking about it or have struggled, I feel your pain. The first time I tried I spent a day getting nowhere. The key is gaffer tape. I think I have a repeatable process now.
Required -
air shot compressor or equivalent
Gaffer tape
Sealant
Track pump
First tape all the way round the rim on both sides creating an airtight seal between the tyre and the rim. Very important- put it on with enough space for the tyre to expand, ie seal it down well on both the rim and the tyre but keep it loose in between.
Take the valve core out and give it a blast with the air shot / compressor. With the tape on, sometimes this is enough to get a not bad seal between the bead and the rim and you’ll hear the bead snap into place. Try and get as much of the bead on as you can with a few blasts. You’ll probably still have air leaks though as you haven’t added sealant yet.
Deflate again and add sealant. Spin the wheel for a few minutes and slosh it around at different angles.
Blast again, and it should seal much easier now. Put valve core back in, remove gaffer tape and use track pump to bring up to pressure. If you have slow leaks spin the wheel again and repeat until fully sealed.
Took me about 20 minutes per wheel this time.
