Over inflating tires better mpg on long road trips?

[AggieSVT]

I took a road trip up to colorado in my raptor this past summer, after 2000 miles of driving there and back my average mpg was 16 with a dirt bike in the bed and luggage. Also did some offroading. I think it mainly depends on your driving habits..

Some clown posted on FB that he was getting 16-18 mpg. That too me sounds like you're either playing a video game or you've never owned a raptor. Who can drive these lightly? When the light turns green, I always check my 0-60. :-D

My right foot can't stay out of it...

However, I wouldn't risk wearing the tires by over-inflation.

Just use helium, no brainer

That's probably the best post here for this MPG thread, love it!!

When my truck was new and prior to 35" toyo mts and suspension upgrades I had a 90 mile highway commute, I would average 16.3-16.6 after a week of driving back and forth to work.

Switch to the off-road screen and ignore the mpg thingy..

there's a drastic difference between over inflation of the door sticker pressure, and the sidewall max pressure.

The door sticker is what, 35 psi? The tire sidewall says 50 or 55 psi. The door jamb sticker is given for a mix of comfortable ride, handling, capacity, etc. The sidewall number is for max tire payload the max pressure you should safely run.

I always run mine a few psi above the door jamb sticker because I don't check it as often as I should, so when it slowly drops over time, by the time I check it and top it off again it's still at or above the door jamb sticker. I also measure my tire tread center and outer at every 5k tire rotation I do and they're wearing evenly. IIRC the door jamb says 35 and I run ~38 and tires are wearing great.

Now if I'm towing (~7500-8000 lbs), I'll bump the rears up to 50. It definitely helps stability when towing as well. If I've got a long road trip (3-4 hours or more) I'll bump all 4 up to 50. Rides slightly rougher, but hey every bit helps on fuel economy. It's over-inflating in the sense of the door jamb rating, but not over inflating in the sense of the tire's safe limit. For an hour drive or so, I don't bother, I leave them at 38ish.

Yeah cruise control highway I get. 16 is pretty much the max. 16-18 around town? Highly improbable.

if you really want better fuel economy the drive a Prius. The accelerator on the Raptor should be treated like a light switch...its either on or off.
