hey all,I have a 1990 Toyota pickup with the v6 3.0 auto transmission and 4:10 gears.I have been running 31x10.5s for a while and made the bump today to 33x12.5s.I used to cruise around in o/d at around 2800-3000 rpm now its down to 2000-2500 rpm in o/d.My question is would it be more fuel efficiently to role in 4th gear with o/d off?

thanks
