Default what would 31x10.5s do to my 2.3l 5speed?

i have a 2009 2.3l i4 5 speed ford ranger.all stock. and i would like to put some 31x10.5 all terrain tires on it i get about 28mpg now and pretty good acceleration... would i still get around 23 mpg and fair acceleration with the new tires? or would it just completely bog down the 4 banger? and would i need to lift my ranger any????
Thanks CP

Really depends on what gears you have in the rear.

You might want to re-gear to 4.10s so it can push the tires around easier.
