Toytec Boss 3"

My guess is also much better than 13

 

Kmitch, so what would the math be going from a 235/75/15, to a 31x10.5x15. Tire calc says 7.3% increase? I average about 250 miles till the gas light is on, and it usually takes about 15.25-15.5 gallons. What would be the equation to find my true mpg?

 

Where do you get the 1.0317?

Yeah i guess now that i add it up I am doing better then 13mpg...I dont know where i was getting 13...But hey i never did say i was an expert in math...lol

 

You take the miles you drove for the tank divided by the gallons you put in your truck when you fill up it will tell you the gallons on the pump
So if you drove 300 miles and put in 20 gallons you get 15mpg...
I normally get 350 miles to a tank all stock and I put in 17.5 gallons on average about 20mpg

 

Using your gallons used I would say 17.2-17.5 (250*1.073=268...268/15.25=17.57...268/15.5=17.29).

Edited for math lol.

 

Actually should be 1.0327 but close enough. Your current wheel/tire is 31.6" diameter divided by your old (assuming they were 265/70/16) which is a 30.6" diameter means it is 1.0327 times the size of the original setup.

 

Yes, if the odometer is correct, which his isn't due to a larger diameter tire.

 

Gotcha!!!

 

I only get 14.5 but I have a heavy foot. Still yet to upgrade my tires as well, with ultragauge my mpg shows a decrease of .2 since my lift was installed

 

Aaron, are you still liking the Boss suspension? Have you had a chance to really test it?

 

Anyone running this with 33s? Im curious because factory says "we haven't tested it with all tire and wheel sizes, thinking of a 33x12.5R17. Will be candy with the 3". Also, everyone has pos. feedback? I don't wanna go get an LT kit but I do hunt, fish, mud, etc with my truck so I want the extra edge. Tips? Comments?
