mpg compensated for 33s

i know with a bigger tire you cover more ground than your speedo thinks. so you are in reality getting better mpg than if you do miles on your trip OD/gallons used. so about what would my REAL mileage be with a prerunner on 33s just round about? i know ppl clam 16 highway but is that real mpg or not compensated for the greater distance traveled?

 

There's a tire size calculator on the forums. It gives the tire size difference in a percentage. You basically multiply your total miles diven by that percentage to add the extra mileage from the larger tire size.. then divide by gallons. Say you went 300 miles. 300x(tire size difference percentage) = actual mileage.

Ex. 300x1.064=319.2 actual miles.

If that makes sense. Lol.

 

see my sig for fuelly link and do the math.
