Does anyone know what size tire is on the non-TRD/non-limited/non-Texas badged regular base DC's?
I have a TRD that came with the 265/70/R16 BFG. I tow a (smaller sized) travel trailer and during spring break we traveled over 1,500 miles with it. Towed great in overdrive (5th gear) for the most part and the highest tranny temp I saw was 145 degrees in the Ozark Mountains in Mo. & Ar. Of course I had to kick it out of overdrive when we hit 20-25 mph head winds and for the constant hills we went over. Best mileage was 15 mpg (following my grandparents Class A @ only 55 mph and possibly had a tail wind) worst tank was 9 mpg with an over all average of 11 mpg for the trip.
I feel if I had just a little extra torque/rpm's while in 5th gear it would give me better acceleration/power for holding hwy speeds up slopes and in head winds. So this is were my idea of betting a smaller sized tire for at least the rear wheels while towing comes to play. I've done the calculators on 4lo.com and if I went to a 245/70/16 tire it would give me an effective rear end ratio of almost 4.10 (my stock is 3.92 right?). This would on average increase my rpm's by a little over 100 at hwy speeds (65-70 mph). What does everyone think?
