My front wheel 28 mm GP5k tubeless on Zipp 303 firecrest hookless measure 31 mm. I run it 55-60 psi

My rear wheel 30 mm GP5k tubeless on Zipp 303 firecrest hookless measure 33 mm. I also run them 55-60 psi. These pressures are measurably slower than optimal but the comfort is worth it to me on my worn, broken, ****seal roads.
