The drawing with dimensions of the dominator 2 rim is here:
The distance from the landing surface (ERTO) to the inside of the bead is 7.19mm on the production drawings.
Note the way that the bead is narrow in height. This is designed like this so that there is more space for the bulky bead while keeping with the correct ISA OD dimension.
I designed the Dominator 2 rim to fit the Nightrider tyre V1 when “the tyre guy” used to make them in Taichung. The Newer version of the tyre has a similar bead due to the manufacturing method used to make these tyres. These are very different for the vast majority of modern cycle tyres. These are no, and never can be, tubeless tyres produced without remaking all the tyre tools (I have discussed this in the past on the forum and have discussed with the factory several times) .
The Nextie rim is working on Tubeless dimensions as I explained earlier in this thread. Adding the bead where they have added it may work with modern tubeless ready tyres, but I do not believe it will be a good solution on the 36" tyres.
