i'm getting mid 19's on highways and low/mid 18's on street on my 35's.

Wow!!! I can't break out of the 13s to save my life and I've got nowhere near the tire and lift you do!

im running 37's with 5.13's on 3.5" lift and I'm at 15 city/16 highway

clearly I'm doing something wrong. Our toll roads run at 75 to 80 mph...maybe that's it? Different thread I guess, sorry for the hijack

The force of aerodynamic drag (Fd) regarding an auto is the product of the drag coefficient (Cd) times the frontal area (A), multiplied by the square of the velocity. Overcoming Fd requires a propulsive force rising as a cube of velocity. An ordinary car traveling at 40 mph may require 20 horsepower to overcome aerodynamic drag, but this would rise to 160 hp at twice the speed (80 mph).* * Horsepower to overcome aerodynamic drag Compare the Cd, A, and CdA of a stock Wrangler to other vehicles here: Vehicle Coefficient of Drag List - EcoModder

Nice! Makes sense, thanks!
