watch the youtube videos i’ve recently done a few tyres (non tubeless no problem) , joe’s is an ok video as is stans. (main difference being inserting fluid through valve core or the bottom of the tyre before putting into the rim
dont bother with the yellow stans tape, i was chatting to a lbs guy and he swears by gorilla tape, £2.80 a roll, work out the width on inner rim and tear, or put a slight cut to start the tear, it will then tear around the roll pretty straight. once taped put in the valves put the tyre on and either seat the tyre and add fluid through the core or as stans, pour in just before the final bit of tyre,
i used a joe blow pump and it gave a reassuring bang and crack when the tyre seated.
hold the tyre two handed and shake whilst passing the tyre around, so the sealant fully covers the inner, then rest on a bucket each side for 10-15 mins.
good to go
