oh and all you guys that're getting like mid 30's mpg, about how fast do you drive on the freeway?? cuz just this weekend i sorta did alot of driving?? i guess, well i have 135 miles on it... and it's like 1 hash mark above the half point on the gas gauge =|, i feel like my car just gets crap mileage for some reason, and i did do mostly highway miles this weekend too so i dont know man eff

sorry for 3 posts in a row but a question to those who get crazy mileage... do you guys have rims?? or are you guys on stock wheels/tires? cuz having rims makes a difference in the mileage especially if you're on 205/40/17 profile tires cuz the circumfrence of the tire is smaller than stock tires so your tire gets a full rotation faster than stocks, causing your mileage gauge to be incorrect, i think i read that somewhere on a post about wheel sizes etc. about the % error you'll have in your mileage when getting rims and tires

Rims play a roll in milage, about 3-5MPG. Different tire can even affect it, for instance sticky tires that grab well will give you worse milage because there is more rolling resistance versus hard highmilage tires. The rims and tire also have a MUCH larger rotational weight now, even if your new rims are lgither, you've moved the weight further from the center, so now the motor most work harder to turn the rims/tires, wierd concept but it's true. If you want really good Milage, get HX or even hybrid rims, they are light and small rims.
just FYI, when I had my 17's on my old 7thgen, I notice about a 3 MPG drop, but I drive 50% city and larger rims are bad for stop and go, that's where I lost most of my milage.
hm.. okay, so if i get rims i can expect the mileage to be a little off because the total circumference of the wheel is gona be smaller than my stock wheels? i know that weight makes a difference in mileage and stuff, but doesnt the wheels being smaller or bigger make a difference too? cuz your mileage is gauged by how many rotations get clocked, and if you were to have a slightly smaller total circumference, it'll rotate more often so it'll say you're getting more miles than you really are.. correct?? or am i wrong?? i'm not sure, so if someone could enlighten me about this

Well, it's kind of complex, because a smaller overall diameter means you will have less distance covered by the tire, that is correct. Now if that is good or bad is a different story. For the city, that is good, becuase now the car doesn't have to work as hard to get moving, that is countered by the fact that the weight is further out (this is called raising the moment of interia, this is bad for city driving), so you have a plus and a minus, which way it goes I don't know with out knowing the moment of interia of you specific rim/tire and a few other things.
So city is between good and bad, not sure where; but highway is bad, because now you have a higher moment of interia, so the car has to work more to keep the same speed, and the RPM's are higher so you're engine is working faster hence burnign more gas (that short for a long story of why).
Now there are many other things that drag into this, and that is why I can not say more than my personal experience and that this CAN affect your MPG. Reason is because there are things like air drag and bunch of other things I couldn't begin it predict that can affect your MPG, you would almost need a degree in applied physics to calcualte the exact drop or increase. I do know that sticky tires and wider tires are a big player, I've noticed that first hand.
if you want good MPG, you should have hard skinny tires.
Here are my pictures about how the milage is showing up and the gas guage indicator moves.
I always use the trip B (~Benzen) to count the miles on a tank of gas. I reset every time I fil up.
Right now all I can get is 36ish and around 370 miles but I'm on 17s(correct tire size) and Magnaflow Exhaust. So I'm not doin so bad sinc it would be a lil closer to 39 with steelies.
I get 27.........is that bad?? i have an 02 ex(auto).....what can i do to bring it up? i drive concience (most of the time) he he......... is 27 normal??? im reading all these 37 and 40 mpg and wondering why i cant get that?
