Hey.... I know you.... haha


As for me, I get RAPED on winter fuel. With 35's I have to use quite a bit of throttle and with snow and ice I like to give it some gas. I still am managing 16 l/100km (13/14 mpg)

 

So I guess I have the worst mileage around for a stock 2010. Let me tell you all that I take absolutely no pride in this.

 

My daily commute is 8 miles one-way. My gas mileage really takes a hit in the winter. Did with my old 97 F-150 too.

 

Yes, my mileage is terrible...I dont know the summer mileage, as I have had truck for 3 weeks and 650 miles. I drive nice and easy, and am at 12 mpg. Of course since 12/5 we have had a lot of snow its been between 10 and 25 degrees and a lot of driving has been in 4 wheel drive.

Nothing gets good mileage under those driving conditions. I only get about 14 around town and 18 on the highway in the winter - about 2 mpg less than in the summer. If I had 4wd and used it, it would probably be even worse.

 

I'm in the same boat as you (30 inches of snow in December) with heavy lake effect that has caused me to have to drive in 4WD quite a bit. I wonder how much the 4wd affects your gas mileage? I've dropped about 2 MPG over the month. Don't know if the winter blend or 4wd has more of an effect....the beauty of living in NE Ohio.

 

Averaging 15 L per 100 KM with mostly city and 401 rush hour traffic (slow as hell). The winter formula is out now ... Highway off rush hour it's gone up to 11 per 100/km.

 

Where are you getting 40 psi from . The cold inflation on these 1/2 ton trucks is 35 psi. I believe the maximum inflation pressure is 44 psi. At 40 psi cold inflation your dangerously close to that 44 psi and you could go over.

 

The maximum inflation pressure on a tire's sidewall is COLD pressure. Hot pressure can be well over that.

 

Yes but the pressures in the door jamb and the owners manual are there for a reason. All your doing by going to 44 psi is wearing your tires out sooner and making them hard as rocks. One example of an exception to this is my wifes 03 Honda CRV. The jamb liable says 26 psi cold. However the book says
to go to as high as 35 psi for max loads at highway speeds. I run them at 32 psi and my tire wear and handling have improved, and the ride is not much worse if any than the already stiff ride at 26.

 

That's funny - my sticker says 30 front 32 rear - and I have BFG Long Trails which are P-metrics rated at 35. I run 35 and they ride very nice and are wearing evenly. I have 70k on them. My winter tires (Michelin X-Ice) are rated at 51 but I run 35 in those too.

Running tires at 40 that are rated at 44 is fine as long as it's working for YOU. The higher the pressure, the less the rolling resistance, and the better the gas mileage.

 

"Running tires at 40 that are rated at 44 is fine as long as it's working for YOU. The higher the pressure, the less the rolling resistance, and the better the gas mileage."

Bang on!

The additional mileage gained over the life of the tire from running on a higer pressure is shocking. It could easily pay for those new set of tires from the fuel savings. At 40psi there is no real noticeable difference in tire wear that if they were at 35 psi.
