Nitto Ridge Grapplers Loss of MPG?

For those who run stock size 315-70r-17 (NOT the heavier 35x12.5 variant) tires, did you experiance any real difference in fuel economy?

And what I mean by stock size RGs are the 315-70r-17s, not the 35x12.15x17s which are heavier yet.


Thanks

I personally haven’t noticed any difference in mpg, but Nitto RG does have better wet performance.

Do most Raptor owners really worry about this stuff? Slight variations in MPG after swapping tires? You as the owner purchased a lifted, off road ready 4wd truck with big tires. Was MPG an original factor in your purchase decision? This sounds like a question I see on the TDI forums when researching my wife’s commuter car.

I cannot understand about 50% of the posts created on this website. I would like to see more offroad pics, trip reports, and day to day issues. Less “I’m thinking about selling my Raptor—talk me out of it,” 2 extra lbs of tire rotating mass will kill you, look at my $5000 ceramic paint coating, look at my clean truck with mall crawler rims, and oh my god, I have been waiting three months on my custom truck order and Ford Performance won’t answer my twice daily emails.

It’s a Raptor, man. Go get it dirty. Go find its limits. And post up THOSE topics!

If you prefer other Forum topics I would urge you to stick with those , your post adds no value here.

I ask because I have a set of new RGs in the garage ready to install in my new 2019, and saw a member here continually post that the stock-size RGs cut his fuel economy by 3mpg which is what, ~25% and huge on that truck. I find that hard to believe. My Truck is my DD and sees 20k miles a year or more.

And what I mean by stock size RGs are the 315-70r-17s, not the 35x12.15x17s which are heavier yet. thanks

I feel you... a little.

The reality (evident by the threads and posts on this forum), is that the Raptor is a status vehicle more than it is an off road vehicle for a large majority of owners. Just as a 911 Porsche is a status vehicle more than a road course vehicle for owners. Replace Raptor or Porsche with any other consumer performance vehicle, and the results are the same... people buy them because they are desirable and cost prohibitive to others, thus to some degree rare. And of course to satisfy their own desire for performance.

I would venture a guess that over 50% of Raptors will never go "off road", and the majority of the remaining 50% would hardly see more than dirt roads and fields. Maybe 15% would subject their $70k new truck to rock crawling, wooded trails, or even high speed desert running.

i have about 15k miles on my 35x12.5 RGs... consistently getting 11.2-11.7 mpg - only other mods are bbk intake and mbrp exhaust. don't think stock tires were much different mpg on my truck.

Some of us don't like throwing away money for no reason. Assuming 12k miles a year, a difference in 2 mpg with cost of premium at $3 is almost $300. That is the cost of entry for TRR. Sure, I realize most that can afford a Raptor consider this trivial, and to some degree it is. But more money is more money, and if it wasn't a substantial factor for most people, car companies wouldn't be driven to make engines more fuel efficient.

The reality is most of our time is spent on pavement, except for the select lucky few. So, things like daily driveability and fuel economy make a difference. And that also translates to offroad performance, like it or not.

If you are calling me out, at least call me out correctly. As an engineer, I understand the concept of tradeoffs, and therefore set criteria for my next tire. Everyone does this to some degree, although my research is a lot more rigid than most others, as I'm aware. 2 lbs per tire was about the limit of what I would accept from an alternative tire - 5 lbs per corner translates to about 90lbs overall, and if you want to pretend that isn't significant for on and offroad performance, than you're welcome to do so, but I prefer to deal with facts.

This site has been a cesspool for many years. Most of the reasonable people left a long time ago. Only reason I stick around is some of the newer owners don't know any better, and even in a bog you can find some valuable things from time to time.

I'm also a fuel mileage conscious owner. I bought my Raptor for a DD and drive it almost 20k miles per year. Unlike most others I've been pretty content with my stock BFG's and the traction they offer. Wet, dry and snow. I don't really see any mud because I'm too **** about condition of my truck.

I've read a bunch of comments from people who have had balancing issues with the BFG's. That's my only hold back from replacing my tires with the stock BFG's again.

I've read a lot of good things about the Nitto Ridge Grapplers and very good reviews on them. That's the tire I was considering going with. But if it means a loss of a couple MPG I'll probably stick with the BFG's.

So if anyone does have first hand experience with the OP's question I'd like to hear it also.

I agree somewhat with your sentiment, but it’s a little disingenuous to post this response in this thread, when the very FIRST sticky in the Jennifer General discussion forum is
One and ONLY gas mileage thread please with over 1600 posts and 328,000+ views.

So yes, apparently quite a few Raptor owners, and particularly the “OG” crowd have been posting about this stuff since 2010.

On the surface, the question may seem simplistic, but it’s not just about weight of the tire or tire and wheel combo, but also the compliance, tread pattern and tread compound of the tire which could create an impact on traction as well as economy.

I have not yet replaced the tires on my ’17, but right now my strong inclination is to stick with the BFG.

Anyone else actually running 315-70r-17 Ridge Grapplers have input?

Again, I would expect some small downward trend running these tires over the OEM BFGs, but the report of -3 MPG seems excessive and difficult for me to believe.

Simply looking for additional real-world feedback.


thank you
