Post your MPG on Taller Tires


Recommended Posts

Posted
On your truck with the 6spd, would the 4.10s be more comparable to a 4.88 or a 5.13 with the 4spd?

 

I'm not too sure... But for overall economy and because I've seen more highway miles it may have benefited me more to gone 3.73's...

 

I do however enjoy the extra power and there's plenty... Super fun to drive now... But fun = more gas

 

At 70mph w the 4.10's I'm running a little under 1900 rpm in 6th gear, and a buddy of mine w 3.73's and similar lift/tire setup is a tad bit over 1500rpm.

Year: 2008

Engine: 6.0 Vortec Max

Tranny: 4 speed

Tires: currently 265/70/17 but have 285/70/17 on my stock winter wheels

Gears: 4.10

MPG- on the 265's I average 16 mpg, on the 285's 14.5 mpg.

 

I live in Park City UT, lots of Hills/ Mtns. Gotta love the 4.10's from that perspective. Also, the truck is sporting a 2" level.

Anybody with a 4spd and 35s left besides me, or have they all upgraded to new 6spd trucks?

I'll have 35's probably this winter when my tires wear out!

We seem to be getting plenty of guys with stock setups chiming in, but why wont more lifted trucks get into the game? Is their mileage so bad that they are ashamed to post it?

    • I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff". 
    • Yep mine is on backorder also.
    • The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.
    • Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.
    • Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
