What AT are they running on them? We are most likely picking up a diesel Boss and if I can pick up that kind of mileage with AT tires I’m switching over at the first replacement.

My '21 had Bridgestone Dueler's on it. It was a gasser but suspect it'd be the same or equivalent tires

The tires that have sidewall protection ( duratracs, bfg k0/km, etc) have high rolling resistance.

Currently getting 20-24 mpg on short trips and 26-28mpg on tirps over 40 miles. Towing my boat on a 3,000 mile trip averaged 18 mpg. Currently have 8,900 miles on the odometer. Tires are Bridgestone Dueler AT 275/60R20

Do you think that the mileage difference on a Denali is because the Denali's are full time 4wd.

Denali's today are NOT full time 4wd.

(yes 1500 Denali's were AWD at one time)

Auto, 4wd or 2wd are available now.

(and 4wd lo)

I always run 2wd.

Give it a try!

Running speed and acceration rate matter too.

Cruise is your friend.

I track every fill.

The 'low' mileage ones include towing.

(I've got a few fills not plotted yet..)
