GX550 Aftermarket Wheel & Tire Thread (9 Viewers)

dang i have 275/70r18 SL tires and my total average is 14.7 mpg and i dont drive too hard. my dash shows 250 miles when i fill but have 2-3 gallons left after click. I used to get 270 miles when i was at 15mpg.

i see people only get 200 miles per tank on 35s, how do you do get 300 🤯
MPGs seem to be all over the place with this vehicle, and none of it is impressive.
