The weight difference should not have an impact on highway range. The only significant factors are rolling resistance and aerodynamics when driving at a steady speed. Weight will have an impact when accelerating, but less so when slowing down, since you can use regen breaking to capture some of that extra inertia from heavier wheels.Here is my follow up note I installed a set of Vredestein Hypertrac 245/50/19 104V tires on a aftermarket set of rims. Rims are 19x8.5 +20 offset.i have noticed very little to no impact on range on the highway. The load range is so close to factory 225/55/19 103h I just left the pressure the same. My wheel / tire combo is 6lbs lighter than factory and this seems to make the car feel like it accelerates faster and positively impacts range around town.i think aerodynamics is negatively affecting my highway performance but it's almost counteracted by the weight being less hence no noticeable difference in range
