Hi,

I have a 6in lift. Wanted 35in tires instead of 37 mainly due to MPG since I'm already getting a miserable 12MPG.

However, after looking at the differencse between the two Nitto Terra G2 tires, they both weigh the same. Could this be true? If so, MPG should be the same since they weight the same?
Unless this is a mistake from discount tire online page.

website shows 35 weight 72lbs
37 weights 71lbs.

If you look on Nitto's website, the 37's weigh about 5 lbs more than the 35's.

What kind of gas are you putting into the tires 87 octane or 91 octane.

Weight has nothing to do with it.

The LT tires with offroad lugs have more rolling resistance and more air resistance than street tires. Your lift is going to create more air resistance as well. If your 37s are the same construction as the 35s then I'd expect rolling resistance to be about the same. You will get a small additional air resistance hit though.

The reason why 37s don't weigh much more in general is because most of the tire weight is in the tread area, not the sidewalls.

Does anyone who lifts their truck and put 35 or 37 inch tires on really give a shit about MPG?

Seems kinda silly to even talk about it

It's money. Don't you like money? I like money.
Give me a break

If you like money don't install a lift and 35 or 37s and ask about mpg

Can't believe I'm arguing with someone who doesn't even get obvious Idiocracy references...

Why even buy a Tundra, why not a Prius instead? Some people have good reasons for lifts and bigger tires.

Difference between 12 mpg and 13 mpg is about $1200 per 100k miles. Different tires of the same size can be that far apart, but unfortunately we don't know what the good and bad ones are.

I run 37's with a 7" lift and Premium Fuel only with SC. 15.5 on average over 7500 miles.

What tires?
Any gearing change or other mod that would effect MPG?
Is the SC known to improve MPG with sedate driving?

*No gearing change but I do have the tow package with the lower gearing 4:30.

*Only if you stay off of it. I have a heavy foot and seem to still avg 15.5 btw. This is real world driving with a SC.

* I am running the COOPER Discoverer STT Pro (SOFT!... I will going back to my Nitto Trail Grapplers once these wear out)
