I purchased this and on the tires it lists only 600kPa for the tire pressure. This converts to 87psi. Can you confirm this is correct? It seems high and I don't want it to blow up in my face.
I don’t know if the 1 7/8” ball is the same as a 2” ball thread size if not you could fab up the upright stem with the correct thread size for a 17/8 too fit
