MPG loss when switching to BFG KO2's

[Haydenatx]

Id say I lost about 1 mpg when I switched to 265 ko2s with trd pro wheels

Don't worry, when you add a lift, skids, rack, winch and bumpers you will lose about 5-6 mpg total.

If you are keeping stock size you will only see a few tenths of loss. Everything is additive though.

As stated here, I only lost a few tenths when I moved to the KO2s in stock size and load range C. Stock rims as well. What I lost in mpg, I gained back in fun and effectiveness out on my ranch roads.

I had E-rated stock size Revo's and just recently got the BFG KO2's in the stock size (C rated). I lost approximately 1 MPG.

1 MPG loss seems to be the norm and I'm ok with that. Actually if that's all I lose that's pretty impressive considering the extra weight and agressive tread design.

Just for the record...just switched from the stock Dunflops to the 265 Ko2s and am seeing a .8-1.0 mpg loss... even the C rated are some heavy suckers.

When is the "Winter Gas" going to end?

It's all about your driving habits. Aggressive treads affect MPG for all aspects of driving, so you'll see a small loss there no mater what you do.

Heavier and/or bigger tires affect acceleration; it takes more gas to bring the extra mass up to speed, and larger diameters reduce your torque at the ground level. I accelerate easy, so I probably wouldn't see a huge difference between different weight tires. My wife comes off the line like every green light is on a drag strip. She can't stand it if the person beside her "beats" her off the line. Same with stop signs, and she keeps the same speed going up or down steep hills. With stock tires, when I drive I get between 22-23MPG in mixed city driving. She always hovers around 16-17MPG.

I did a lot of research when deciding which tires to replace my worn-out factory tires; I really wanted to go up 1-2 sizes, but it's her daily-driver and I realized I wouldn't be able to afford her gas bill.

gee your wife sounds like a relative of my wife.

April-June is the "transition" period. Think gas stations have to sell summer fuel by June 1st.

1.5-2 mpg loss, but also had a knock sensor on it's way out, probably much worse until Saturday.

I don't think this is as much a question on the KO2's as it is on non-oem tires and aftermarket setups.

I have owned my TRDORP for 10 days. In those 10 days, 1 tank of premium gas.

Mileage with a 2" ICON lift and 285 Repuslor Mud Terrain tires, my mileage currently shows 14.8.

In my old 2005 Nissan Frontier Nismo running Cooper Discover AT tires no lift. Always in the low 13's mostly due to the thirst AF Nissan 4.0 engine.

But still, I feel optimistic once I switch out the mud terrains for Wildpeaks.

Here is my pure unscientific experience:

I switched from stock Dunlops to stock-size "C" load rating KO2 about 1200mi ago. Since the change, I gained about 0.5mpg (my overall mileage is about 18.2mpg for 70% city driving). How I managed to increase mpg?? It’s all about how you manipulate your right foot.

My previous car was a modified twin-turbo sports car. Since I made the change to this super under-powered T4R, my driving style definitely became much more relaxed and slow-paced. There is no need to keep press that gas pedal because it’s just a noise maker. This change of paradigm on driving helped me to gain the MPG. :lol::lol:

Im getting 14 to 15 MPG around town on 285 E's. Less when off road.

This is why your BFgoodrich tires are gaining better mileage than the Dunlops

Andi...good data.....any other mods to speak of? Is it leveled or lifted? I'm sure your right, I've noticed the mpgs creeping up when I slow from 80 to 74-76 on the HWY

I did a 3" lift and 285/70 E KO2s and dropped a tad less than 1.5 mpg. Oh..and with a full length roof rack too. No complaints here and you made a goid choice on wheels. Im still on ORP originals.

 

[Louisiana Overland]

I'd really like to figure out a variable height suspension setup. My inclination is adjustable front coilovers with rear airbags. So I can bump it up for the 2 or 3 trips a year to moab where I really want more clearance and bigger tires. The rest of the time I'll leave it lower. In a perfect world I'd figure out how to build air adjustable coil buckets front and rear so I can run low on the highway and pick it up offroad without losing suspension travel and feel. But for now I'll just have to settle for stock height.

I would imagine you would see some irregular wear unless an alignment was done with the lifting and lowering. The front end geometry changes with height changes

Stock size, about 1mpg loss.
