Curious what's the diff in total wheel/tire diameter between the OEM 18's and 20"s? Wouldn't the 20's be a lower profile tire which should weigh less than the "air baloon" tires on the OEM 18" rims? Might not be as large of a diff as one might think?
Also, I'm looking for a set of the OEM 20" take offs if anyone here wants to sell a set - PM me - I'd even throw in my OEM 18's (Lariat) wheels so YOU can get better mpg
