About the same 4 mpg difference when comparing the Ioniq hybrids 17 inch vs 15 inch wheels. Seems like higher end hybrids all gain about 2 mpg average for every inch you drop in rim size while keeping the total wheel radius the same

My bad didn't realize it was smaller wheel with same size tire.
For 4mpg it seems like it could be worth it if you sell your old wheels to cover most or all of the cost.
