Lol I thought they felt a lil weird to the touch. That sucks. At least they look good though!

Stock rims are heavier and tougher than aftermarket because they are built to withstand a lifetime of service on a truck.
If you don't haul much weight or run on rough terrain you could shed a few pounds with a wheel / tire pkg that has been rated for hauling the weight of your truck and cargo.
Mostly that is for looks and handling because real life benefits from the weight loss is pretty small.
Low rolling resistance tires is the best mpg improvement in this area.

Check the air in your tires. The dealer's often underinflat them to make the vehicle ride better on test drives. Mine was at 30psi. The door sticker recommends 35psi. This will make a noticeable difference in gas milage.....

Also I have found that slowing down before you reach a red traffic lights is the best thing that you can do in city driving. If it changes to green before you get there and you do not have to stop you just saved a lot of fuel... (Newton's law not mine)

And of course stay out of the turbo boost as much as possible....

I just returned from a Class Reunion -
497 miles each way
Edmond, Ok. - Angleton, Tx.

2011 Eco Supercrew, Lariat 4x4, 3.55 limited slip, ARE tonneau cover, A/C on!


Trip down: 21.3 MPG
details: 87 octane (pure fuel), driving speed limit, no wind, and a one hour massive two mile an hour creep though Dallas rush hour/wrecks/etc.

Trip home: 19.4 MPG
details: 87 octane (ethanol mix), driving speed limit no traffic issues and a massive tail wind!

I think the ethanol made a huge difference, if it wasn't for the huge tail wind I expect the mileage would have been worse. Also, eliminate the dallas creep I expect the mileage would have been slaghtly better. I also recently took a trip to Minnesota driving 75-ish and the mileage dropped to 18.4 for the trip.

I just got back from a class reunion as well, except mine was in Arkansas. Anyhow, I couldn't keep my foot outta the gas on I30. Kept it around 75-80 the whole way and averaged about 17.5 going and about 17 on the way back (big head wind).

One portion of the trip, I was really light on the gas and kept it at 55 mph. I was amazed that I averaged right at 27 mpg. But of course that was only about 10-15 miles on flat land. It's amazing to me that slowing down by only 5 mph can make such a drastic difference.

I have found the opposite to be true for me on this one (although we might be saying the same thing). If I use about 60-75% throttle and can get the torque converter locked more quickly...I see a better average down the line. This only works on longer runs between stops...stop and go traffic with lots of lights...not so much.

I also agree with coasting more helps alot...up to lights and especially BEFORE you crest a hill.....I've always been surprised how well my truck maintains speed off throttle.

Here's an article that states similar results. Not scientific and I'm not saying that this is the best method...but it's alot more fun ( yes...I know that this was tested on a CRX)

I have found this to be correct.

As everyone else has said, they get the best MPG at or under 70 - even a little bit over 70 and it starts falling quickly.
I was able to average 22.5 MPG driving through Wisconsin in mid-summer at 65 MPH, total round trip average through Indiana and Kentucky and back to Wisconsin (Indiana and Kentucky both have 70 MPH speed limits) was 20.3 MPG.

Minnesota, which has a 70 MPH speed limit, I was only able to hit 17 MPG. I have yet to drive through that state when it wasn't incredibly windy, so it appears cross winds play a huge roll in dropping fuel economy.

48 MPH is theoretically the speed where you should get the best mileage because of resistance.
After that wind resistance sucks up more than 50% of your fuel and grows with speed.
Aerodynamics and drivetrains could cheat a bit more but in a truck that's getting pretty hard to do.

I have averaged 23 mpg on a 750 mile round trip two different times.
The most mpg that I have gotten was with a good tail wind, on a 100 mile trip I got 29.5.
This was going 65 mph.
