the difference between a 27" & 28" tire is 32 revolutions per mile or 3.5% difference

just an example as we don`t know what numbers you are working with

Unless the bike is overloaded I expect the difference to be minimal

Using the example above

xx rpm = 60 mph with 16 / 62.1 mph with 18"
XX mph = 3000 rpm 16" / 2895 rpm 18"
Can you source an 18" with lower aspect ratio / height ?
