Will 2:64 and 18spd work with 19.5 tires

I am looking to build a glider with 500 Detroit with Pittsburgh Power Box or Bully Dog. 2:64 rears and 18speed. This is a car carrier and will have 19.5 tires all the way around due to getting height down when hauling large vehicles. What would my RPM's be at 62 in 16th and 68 in 18? This combination works now in company rig and 400 cummins with 10 speed, but RPM's are 1800+ at 68 MPH.

Answer this question I have this problem too

Is this a good question?

Assuming this 10 speed is a overdrive the final gear ratio is .74 the 18 speed has a final gear ratio of .73 so speed and RPM will be almost identical
