I tried Tannus tubeless inserts a few years back. I found that I needed about the same pressures as I did without inserts to prevent tire squirm. At my weight, 145 ish I can run low psi. As low as 15 front and 17 rear depending on conditions and tire carcass construction. 17-20 ish more normal for me. As I don’t pinch flat often and the Tannus don’t support the sidewalls like Cushcore might, there was no benefit to me.
Some other site had a pole of WC DH riders and very few used inserts. I don’t recall why that was.
