the rims are 65 psi max? or the tires? the forces on a rim are different when tubeless, and 2” or with with 55-65psi is a lot of force applied almost exclusively via the tire bead to the rim hook.they are 65 psi max but I am more at around 55.
i couldn’t find the spec on the rims. https://alexrims.com/products/md35/
