Regarding planned mod #6: I am going to need a set of tires in spring once the snowies come off. The current tire size (215/50R17) is not ideal for economy but I cannot do much about it considering my rim size - 17X7.
The 215 size is the smallest size where many aspect ratios are available - 50, 55, 60, etc.
215/50R17 = 25.46" - Stock
215/55R17 = 26.31" - 3.24% increase
215/60R17 = 27.15" - 6.23% increase
215/65R17 = 28.00" - 9.08% increase
It might look kind of dumb with too tall of a tire. Not to mention the ill handling effects.
Will buying a taller LRR tire to decrease my overall ratio (and lower engine revs), affect aero (because of increased ground clearance) and offset any gains?
