[taco]

ok i have been driving an old 81 toyota 4wd long bed to work. ever since my 98 taco 4x4 was bought back due to frame rust( the size of a quarter) but that is a different story.

the truck i am driving is has a 22r motor 2.4l (144.4 ci) motor, and a weber 2 bbrl carb, i really like the sound of the second opening up. but that dont help mpg. it is a straight axle 4x4 with 4.88 gear instead of the 3.90 and has 31x10.50-15 tires instead of 225/75/15,
right now at 65 mph i am punching 3000rpm.
do u think a set od 33x10.5 r15 or 32x11.50 r 15 tires would yield better mpg?
with a 32 and my gears the rpm would be about 2800 at 65mph
and 2700 rpm at 65 with the 33's



stock 65 mph would be 2600rpm.
