OK, after a few days of driving with the stock wheels and tires back on there, my gas mileage has gone close to 18mpg! What a difference that made! I miss the big wheels and tires but it drives so much better with the stockers!

I have a 6.0 extended cab with 265/70-17inch and 3:73 gears. Ninety per cent of driving is on county two lane roads and have averaged 14.6 for just under 5,000 miles. My 2003 with same except 5.3 engine got 15.

NETO, mine does an average of 13.7 on E85 ethanol. That would be an 20% city/ 80% highway driving mix.

Just returned from a trip mostly interstate driving. On the way to destination temp outside 32-34, a.m. time frame, about a 15-20 mph headwind avg. between 65-75,[some stretches the speed limit was slower],using the cruise,traffic about moderate avg.16.4. On the return trip everything pretty much equal except temp was 45-48 and it was in the p.m.,and no headwind avg. was 17.2 Forgot to add that about 50-60% of my driving was in hilly conditions.
