A/T to M/T gas mileage

I am considering 31" Treadwright OTRs, I now have 31" Nokian Vatiivas. What is a reasonable estimate of the loss in fuel economy. My truck is properly geared (4.56) with a 22RE and a 5spd.

i don't think that you will have a noticeable difference in fuel economy, if anything maybe slightly more mpg because very slightly bigger from tread

mine dropped a little personally.

i have a v6 running 33's on 4.56s

i had some OLD 33x12.50's at's that were bald and practically slick so maybe closer to a 32 or 31

then i switched to trxus mt's in the same size (33.1250's)

and i was getting around 18 and now im getting 16mpg.

but i also switched from aluminum to steel wheels if that matters. and the trxus are heavy tires.
