2015 Chev 2500HD mpg

For those it interests:::

We took off a couple months ago and hit primarily the Colorado, Wyoming, Montana, N Dakota ... mostly Rockies.

Dropped the 265 stock tires (they sucked) and installed BFG 285 75R 17 KO, and it really rocks. Smooth ride, very comfortable off-road or on highway.

We traveled 7424 miles on 689 gallons - 10.77 MPG with 4000 wet weight camper load ... 2015 Chevy Xcab 4x4 w6.0L and 4.10 RE

We measured it with gallons and miles - not on the gauges. Altho, gauge shows 10.677 average ... so, pretty close. Not too bad for about 2/3 mountain driving. the 6.0L hauled the weight pretty well, a few very steep grades slowed us down but the down-gears pulled it right up and at high RPM climbed everything we tried...

Very happy with truck performance and new tires - haven't measured tread loss/wear - but will soon as I remember. Some say the BFG won't give good mileage, but I don't see much wear ... and no cupping, no odd wear patterns - very flat across the threads.
  • ....just to confirm: ....have you got the BFG all-terrain T/A KO2 tires ?
  • That's about what I get with mine running the same tires but 275/70/R18. Truck rides nice and quiet with 20,000 miles on the tires and still have half the tread.
    Sounds like a nice trip.
  • I'm glad it worked well for you. I'm assuming you drive about 60 or so, and slower up the mtns. Any thoughts about a truck or camper upgrade?
