Just back from 1100 mile road trip.
08 stock JK Sahara, 255R70x18" Bridgestone A/T Dueler, hard top on.
auto tranny, 373 diff.
From Willamette Valley over 3 mountain passes nearing 5000' each; mud slide & trees, 100 miles of snow 4x4; high winds, heavy rain; high water detour; typical 55-65 mph driving as possible; some 70-75mph but not much; 1/2 of trip was good weather & 1/2 was the 'heavy-high' part; 100 miles urban driving; 50 miles back country gravel/dirt road;
1100 miles/total gallons of gas 49.85= 22.66 MPG
Further; this is 4615 miles I've driven this since purchase at 15970 miles. Used 214.01 gals = 21.56 average including about 1/3 city; 2/3 rural roads & freeways.
Pretty pleased with these mileage figures for a flying brick shape.
