285’s and MPG?

Hey All,

I’m new to the 4Runner world. Just picked up a ‘20 Venture and currently gathering everything for a lift (going with King 2.5’s front and back, SPC UCAs and 2” Icon coils in the rear). I’m planning on either 285/70s or 285/75s on the stock TRD wheels.

With this being my daily driver, I’d like to find the best tire option to maximize mpg. Was wondering if anyone running a lift and 285’s can offer any recommendations on which tires I should look at.

TIA!

If you"re trying to maximize MPG, sell the 4runner and buy a Prius. :shrug:
 
I have been very happy with my Yokohama Geolandar G015 A/T tires in 255/75/17 on my 4th gen. Long life and pretty quiet. They’re a 32” tire, SL rated, only 41 lbs.

You can buy them in 285/70r17 either SL rated passenger tires or E rated LT tires. It’s a 33” tire.

The SL rated 285 tire is only 45 lbs. The E rated 285 tire is 54 lbs. The lighter tire is $203 at tire rack. The E tire is $238 there.
 
Falken Wildpeaks SL AT3W 285-70-17’s on OEM Pro wheels. 51#’s each. Smooth, fairly quiet ride. 2.5” up front, 1” rear. No mods or rubbing. The offset and width of the Pro wheel along with a 285/70-17 allows for the best clearance with the least amount of mods. I get 15 +/- 1/2 mpg street. Waiting for a road trip to check hwy mileage. It’s a 2 1/2 ton brick. Don’t expect much. At $3 per gallon on a 1000 mile road trip, the difference between 16mpg and 19mpg is $30. Even if you are doing as much as 3k a month, $90 extra is nothing.

That’s a great point. When you break it down like that, it’s really not that big of a deal.
 
I'm running 285/70/17 SL load Toyo AT3's on Method 17x8.5 wheels. I've got a winch on a budbuilt mount and a heavy steel RCI skid plate underneath. Lifted about 2-3/4" up front and 1-3/4" in the back. The toyos are actually the third set of 285's I put on it in about a months time. Started with Falkens which I loved except they WOULD NOT balance. Not even remotely close. Went to C-load BFG's which were almost as bad. 3 days later went with the Toyos. Still waiting for a credit on the Falkens and it's been six months. Don't buy tires from secondary non-official dealers of tires.... Anyhow. I'm very pleased with the Toyo's and in mixed new england driving I average a bit over 19mpg. If I take a long highway trip fully loaded it goes down to like 17.5 if I'm going 75-80. For what it is it's great. But keep in mind I'm pretty easy on it too.
 
I was worried about losing too much MPG when going up to 285s, too, but you'll get over it. Like everyone said, it wasn't great to begin with anyways. I think weight makes the most difference, the heavier your setup, the more you'll lose. I went from Nitto Terra Grapplers in P265\70\17 @ 44lbs each on 20lb wheels, 64lbs per corner to Toyo RT LT285\70\17s @ 60lbs each on same wheels, so 80lbs per corner. I went from averaging about 17.3MPG to 16.8MPG. what I noticed is that it's more sensitive to how you drive. I can still see MPGs in the 17s if I'm really easy in gas, and do mostly highway\feeeway driving, but once you hit stop and go city diving it drops quick. I feel the benefits of stepping up to 285s out weigh the loss in fuel efficiency

I bought my 4runner used, from a Toyota dealer. Already had 285's on it, so I never missed the pre-285 mileage.
Getting 16-18 mpg

I read in some other threads that the KO2 aren’t particularly great in wet or snow, so for that reason and the weight of them, I wasn’t planning on going that direction. I had a set of Toyo AT3s on an early Bronco and liked them, but that was strictly a for-fun-only vehicle and I wasn’t at all concerned with cost or mpg or anything like that. I see a lot of people running them on their Runners... thinking they might be a good option.

FWIW I have had the opposite experience. I've had the older BFG KO and now BFG KO2s on multiple vehicles over the years. They are amazing in the snow and suprisingly capable offroad vs. other ATs I've run. They are quiet on the road all while being fairly aggressive, especially for an AT. I am still confident they are the most consistent and one of the best tire buys out there. Snowflake rated, 3 ply sidewall. Not much here not to like.

With that said, I have not run them on a 4runner yet.
 
Mileage report after driving 2,667 miles from Pittsburgh to Seattle back in July. These were all hand-calculated.

1st fill: 17.9 mpg
2nd fill: 18.1 mpg
3rd fill: 18.4 mpg
4th fill: 14.6 mpg < spent most of this at 85 instead of 75
5th fill: 16.5 mpg < lots of "city" driving
6th fill: 19.0 mpg
8th fill: 18.5 mpg
9th fill: 16.6 mpg < lots of long uphill stretches

Couldn't calculate the 7th fill, some little hippy girl was bumming gas so I filled her 5gal can up while I was filling my tank.

285s with 2.5" lift.

Gas, grass, or ass?
 
275/70 TO 285/75 MPG dropped by .1
i have a lot of stuff in the car.. and i'm not the most eco friendly driver.
13.6 mpg ..
 
I'm simply looking for recommendations on types of 285 tires that will yield better mpg than others. I realize that I'm not going to get good mpg with my vehicle choice, but I don't see anything wrong with trying to get the best mpg that I can given my desired set up.

Run away from Patagonia MT tires, aftermarket wheels, and a lift. That will kill your MPG. 13-14 mpg dead.
 
Dobinsons 2.5/2" lift, 1" body lift, 285/70 on OEM Trail wheels, HeftyFab front bumper/sliders, full SSO rear bumper w/jerry can holder, 100lb subwoofer box in the cargo area.

I average 16 city and highway.

I have never heard of these before but have seen that weird treat pattern.

How do they perform?

Looks like they'd be prone to some chunking and weaving behavior on road.

They make noise, so far I am otherwise very happy with them, have not really put them through anything. They do perfectly well on fire roads, but so what. This winter will get some sand, mud, and snow under them.

On-road manners are fine.
