#337 of 345 another 40... by nippononly Oct 01, 2009 (3:42 pm)
it would appear that my choice of new tire has indeed reduced my fuel economy by 2 mpg.   379 miles, 9.4 gallons, 40 mpg.   If I get much better wet traction than the precious little I had before, I guess I might call it an even trade...   '02 5-speed.

Replying to: kneisl1 (Oct 01, 2009 3:49 pm) You can say that again!   It was immediately apparent when I got the new tires that they were much softer than the old ones, and probably have much higher rolling resistance as a result. One consequence of that was BOUND to be lower fuel economy, but the ride is softer now too, which is a plus, and if I do end up getting lots more traction in the rain, I guess I will call it even.   They are very grippy!

Replying to: bottgers (Aug 28, 2006 10:33 am) Coming from Edmonton (northern Canada) where temperatures are often under - 20 degrees Celcius (-4 degrees Fahrenheit) Although an electric block heater acts as insurance for getting the vehicle started on frigid mornings, there still needs to be a warmup period to get the ice scraped off the windows and the windows all defogged... so we certainly are at the 20% drop of efficiency. And I was interested when the "Mythbusters" TV show did a "A/C vs Open Windows" episode showing that at speeds over 55 mph that A/C is certainly more efficient than the open windows that cause lots of drag due to air friction... especially for sedans that are more streamlined than SUVs. Open windows decreased the mpg by about 20% !!!!!! Below is an interesting link about a similar study... with references. /denis">link title

I have a hard time believing that open windows would make your mileage go from 40 mpg to 32 mpg on the freeway at 75 mph. Maybe its true? Replies to this message: dake (Oct 03, 2009 1:43 pm) thegreyone (Oct 04, 2009 12:05 pm)

Replying to: kneisl1 (Oct 03, 2009 11:59 am) Drag increases exponentially with speed, so I wouldn't be totally surprised. Replies to this message: thegreyone (Oct 04, 2009 12:05 pm)

Replying to: nippononly (Oct 01, 2009 5:17 pm) I once read somewhere that when tires are brand-new, they will get less mpg because of the mold release stuff still on them. I don't know if it's true or not. Replies to this message: nippononly (Oct 04, 2009 10:34 pm)

Replying to: dake (Oct 03, 2009 1:43 pm) And I'm also not surprised that the windows down doesn't make as much of a difference for the more box-like SUVs compared to the more streamlined sedans and coupes. But 20% change in gas mileage is significant.

Replying to: mcdawgg (Oct 04, 2009 5:23 am) Well, I hope so, because I want my 42 mpg average back! :-|   Certainly as tires age, the rubber hardens even if they still have a lot of tread, and that hardening decreases traction but increases fuel economy.
