if valve creep is from under inflation you’ll have to address that somehow. if the bike isn’t for you then maybe you can move past your personal preference for 75 psi & let the owner go up to 80 or 90 psi. also doesn’t it depend on compliance &maintenance? meaning check pressure regularly & not waiting for it to “look” low. when I was a kid i never used a gauge just squeezed them & filled them when they looked low. Then tilted valves were common. We use shrader valves on all 6 family bikes & never have tube creek or tilted valves & my Wife & Daughter both prefer less pressure than Son & I. the bikes only get ridden after the psi have been checked
