No mods, all stock.

Interstate: 65-70 listed

2 drivers averaged 23 MPG one day. (Southern Oregon to past Bay Area, CA)

How do you like the 245's? I run 255's but recently I've seen that size in some all terrains. Curious to compare weights and wondering how they do in snow.
Its not even 1/2" so probably not much difference.

The tires came with the car when bought so i cant compare to the original 265s. Tire size calculator says the height difference is only 0.06" or 1/16" compared to stock 265/65-17. When the time comes im looking to go with 255/70-17s. I also have no experience in the snow, we dont get that here

I think this needs an update lol

I'm not sure but I think this is after I installed the speedometer healer which corrects the speedometer which in turn corrects the odometer to compensate for the larger tires. So by manually correcting for the 12% difference I doubled up on the math.

So I think my actual numbers with 35's were:

@73mph 16.3mpg
@80mph 14.5mpg

With 37's I think its closer to 11 or 12 in town commuting.

Stock 2006 V8 Limited on factory 18 inch rims. Blizzaks in the winter. Kumhos the rest of the year.

16 mpg city/highway mix but mostly gentle highway cruise. Calculated on the trip computer and actual calculation of fuel used and distance traveled.

Occasionally 17 - 18 mpg if I don't drive too much stop/go.

Using the smaller US liters (3.78) to one gallon conversion. The Limited V8 is awd all the the time. About $75 USD to fill up every 2.5 weeks. Not bad for the vehicle that is this capable.

19mpg? Dang man! Good on you!! Thats awesome.

Anything else you want to add: I feel like I am getting worse mpg than others. I am slowly going through the truck and changing everything out. Fluids are being done next. So far the brake fluid and power steering fluid were black from the PO.

My ultra gauge says the average is 14.6mpg, but I forgot to reset it before I went on a trip this weekend. LCD screen says around 15.7.
