I'd like to give my FFE a bit more aggressive look and so I'm considering replacing the wheels with black 18" (which would require 225/40-18 tires). This raises several questions:
1. Does spoke design have a significant impact on wind resistance (and thus range)?
2. A 225/40-18 will lower the car slightly from the 225/50-17. Is this likely to reduce drag (and increase range)? Will the effect be noticeable?
3. How does one re-calibrate the spedo for the slightly smaller wheel?
4. Unfortunately the Michelin stock tires aren't available in this size. Any recommendations for a LLR tire in this size? Obviously I don't want to give up any range to rolling resistance if I can avoid it.
Thanks!
