Hoosier Slicks

I'm Back... Just bought a new pair of slicks for the race season, Hoosier Radial Slick,#18212 9.0/30.0
I noticed when they were beside each other that one stood taller. So we measured them. 92 3/8 & 93 3/4
That's quite a difference as the Hoosier chart says they should be 94 inflated I imagine?
I haven't mounted them yet but want to see what others thought before mounting. Once they're mounted that's it,doubt I can return them?
