You could
estimate the trade-off, but only if you know the difference in rolling resistance between the two tires you're comparing.
The negative impact of increasing tire width on Cd has been quantified on numerous vehicles.
See:

Don't forget frontal area also increases slightly with wider tires.
If you know the values, you can plug them in to the aerodynamic drag / rolling resistance tool:
