Lower Gear ratio better mpg?

(recommended tire: BFG - Rugged Trail)

Everyone I know that has bought these tires has complained about how quickly they wear. Just a FYI.

We all know this vehicle isn't cheap on fuel. Is it just me, or are others surprised how some are willing to invest serious coin to modify something or buy a different vehicle to get a few more MPGs...have you ever calculated the break even point on that cost?

Let's assume you do some modification that costs $1,000,and it increases MPG from 16 to 20 MPG....a full 25% increase, which is doubtful.
16MPG x 22.5 gallons = 360 miles per tankful
20MPG x 22.5 gallons = 450 miles per tankful
If fuel is $2.95/gallon, you gain 90 extra miles per full tank
90 miles ÷ 20MPG = 4.5 gallons to travel that far
$2.95/gallon x 4.5 gallons = $13.27 saved on a full tank
Another way of looking at it is you save .029/mile.....

$1,000 ÷$13.27 = 75.35 tankfuls....for most, filling up every 2 weeks, that would take 3-4 yrs to just break even.....and only then would you begin saving any money

Maybe for tracking MPG, you might look into registering at fuelly.com. It's kinda fun. Here's my VX:

Billy--- The BFG - Rugged Trail only has 10/32nds tread depth when they're brand new off the shelf. So compared to say a General - Grabber AT2 which has 17/32nds brand new-- then yes, the BFG - Rugged Trail will have a short life right from the start.

What makes the BFG - Rugged Trail so unique is it's the ONLY "P"-series tire made in size 275/70R18 with a tall O.D. of 33" and only weighs a featherlight 46 lbs each. Take a peek at TireRack.com for all tires made in 275/70R18 (33" O.D.) and you'll quickly discover that all of the rest are much heavier "LT"-series tires easily weighing 10 lbs more in the ballpark of 56 lbs each.

Remember; for best MPG we want tall O.D., narrow width, and super lightweight all combined in one tire. Class dismissed.
