I consider myself a good engineer, but sometimes things take a while for me to figure, especially if it's a project that I'm not concentrating on... like why my gas mileage is just below average.
I think about this every now and then (like when I fill up) and it seems like my mileage sucks! Usually I chalk it up to:
1. I hammer on it a lot
2. I am usually speeding
3. At least once a weekend a Honduh Riceboy gets a lesson or 2 from me
4. Sometimes I dont fill the car up ALL the way
5. I drive in traffic a pretty good deal
6. I drive short distances
Then last night it hit me! On SE-R.net they have a spreadsheet of the speed variability of changing your wheels. The classic stock wheel is a 185/60r14. I have a 205/45r16. I'm going to go crunch some numbers now and see if that is why my mileage is different. Physically, if a larger diameter wheel/tire is on a car calibrated for a smaller diameter, then you should travel FURTHER than the stated mileage!
What do ya'll think?
