Economy after larger tire

2007 grand Cherokee diesel, engine is notoriously high revenge for diesel and many said that much lower gear would be nice to have. So I got new tires and I went up from 29.5" to a 32" diameter tire. Before with the old worn 29.5" tires my average fuel economy was 10.5 l per 100 km Now with the brand new all terrains it is 11.2 But the odometer used to be showing 5% too fast now it shows 6 km to low so I don't know how to calculate that extra percentage into the calculations. I basically go almost 10% more than I did before so the slight increase still shows like it should be A benefit Big because I cover more distance. After the first 80 miles average is down to 10.9, but i also changed axle and transfercase fluid. Gps verified distance traveled, 170 but only logged 159 on odometer
