    How do heavier/wider tires at the same rpm getting you better mpg?

    The engine is doing less work to spiin the larger tires. Less work = better mpg. Larger tires add much more rotational mass to the drive train. Re gearing can give the engine more leverage in which to turn the tires. More leverage = less work= better mpg. I dont think I was able to do any accurate highway testing to be able to draw an accurate conclusion as to a gain.

    So what are you recalculating if the ODO is accurate?

    Tire size. By increasing the tire size by 7.4% (Which I did), I added that to the odo when calculating my MPG. On my Dodge, as with most vehicles, changing tire size affects the ODO.

    AS can be seen in the graph (tranny tested in a 1:1 gear) 4.11's and 33" tires, will put the truck only 92 rpm higher at speed, than the stock gears/tires combo.

    I got 33"s and though I should go 4.56 when I regear in future, but now I see that 4.10 is better from this thread and the chart. Maybe better for lil more power back to go with thee 4.56 since overgeared more, but 4.10 is still over from stock...

    I prefer 4.10's, as you are still slightly "over geared".

    So basically i'll go back to how it was stock before the 33's?? And would that mean that 4.56's are even higher "over geared"?

    Yes. The 4.56's would put you about 400 rpm higher at speed, than what stock with 31" tires would be.

    Chris, what should I expect to pay to have my new gears installed in my rear differential?

    For parts and labor, figure about 500 to 650 per axel, depending on the shop. Its about the best mod for the buck you can do for the truck.

    Any recommendations of where to go in Phoenix? Also, with 255's or 285's and 4.10's do you think my MPGs will go up from what I'm getting with 265's and stock 3.73's?

    Hey Chris, this may be a dumb question but I heard there is a difference in sizes when it come to a Tacomas pumpkins. I heard that because I have a locker I have to get a ring and pinion for a 8" and all others can use the 8.4...I'm not sure what this means :eek:

    Help :confused:
