My current 2007 xterra is on 33 inch load range E k02s. For 5 years now I have driven on 3.13 gears(shit per gallon millage ) but I finally have the option to get a m226 with 3.69 gears. My question to yall is will this help bring back up millage to compensate for the larger 33 inch tire as well as it being a much heavier tire?

I have a manual with 3.69 gears, the same tires as you and I get around 16-17 on the highway. Not great, but not terrible for a brick of vehicle.

Mine is an automatic but currently on my gears being 3.13. Stock tires had me at 16 ish mpg. With the ko2s I'm 13 on a good day. Average about 11.

I would think with 3.69 it will improve.. at the least it will be more fun.

I have the same truck that OklaYeti has (6spd, P4X, sliders, aftermarket skid), 33" LR E tires and I get about 17-19 on the highway. I did a trip from San Jose up to Lake Tahoe last weekend and got 19.5 MPG on that tank. No offroading. I also drive fairly tame, I don't think I ever exceeded 80mph and mostly was around 70-75mph. Those mpg numbers are 'corrected' for the non-stock tire size. Are you correcting yours or just giving us the number from the dashboard? That'll be about 3.6% shy of the actual number ...
My advice is don't do gears ONLY for mpgs. Do it because it'll make the truck more driveable with those big tires, maybe even go bigger on gears if you're actually gonna spend the money.

Mine was 16.1 on the computer going from Oklahoma to Colorado, so quite a bit of uphill. I'd say its in the ballpark of 17 around 75-80 mph.

This is all for offraod setup thus why I'm getting the m226 with e locker but the mpg is the bonus on top just to help with my larger heavy tires
I won't go any higher gearing for a while

You have to do the front gears as well if you put that M226 in, so keep that in mind.

Already pulled the m226 and matching front diff
