What helps reduce aerodynamic drag better wheels inside or outside in reference to the above designs? please help.
Tire Placement for Aerodynamic Drag Reduction: Inside vs. Outside Designs
Click For Summary
SUMMARY
The discussion centers on the aerodynamic drag reduction of tire placement in vehicle design, specifically comparing inside versus outside wheel designs. Participants agree that while placing tires outside may reduce frontal area, covering the tires can significantly lower drag. A calculator was recommended for initial approximations, although it is noted that Computational Fluid Dynamics (CFD) analysis provides more precise results. The conversation highlights the balance between frontal area and drag reduction through tire coverage.
PREREQUISITES- Understanding of aerodynamic principles in vehicle design

What do you think? What research & reading have you done so far? Is this question for schoolwork, or are you designing such a car for yourself?

yes this is for a project I am working on. According to my knowledge tires outside should be better since the frontal area reduces as compared to when the tires are placed inside. As the area increases the opposition also increases. But also the tires being covered reduces drag over the tires. thus the confusion.

Look at this calculator (and the theory at the bottom of the page). It's not as precise as a CFD analysis, but it is a lot faster for first approximations.
