Best fuel mileage 18's

18x7.5 Didn't want to go too wide. Also is your heater on? AC? Mine for the most part are always off to make sure to get as much MPG as possible, since my commute is like yours 60-70 miles a day.

Getting gas in a few days and I will divide the mpg the old fashion way to get a more accurate number.

 

Finally got gas. Divided the numbers the old fashion way and the end result is ... 52.62 mpg. Trip A computer assessment wasn't too far off before getting gas was reading 54 mpg.
No AC/ No heat ever on for the full cycle of gas and tires maintained at 42/40

OP good luck on your MPG sir..

 

I'm stumped: where is "I.E"? Guessing it's in the USA, but it doesn't appear on this:

U.S. State Abbreviations & State Postal Codes

Ireland? " (.ie website code for that country.)

 

I wouldn't mind Ireland but i'm in the Inland Empire area of Southern California.
