Should i do 275/70 bfg or 285/70 nitto terra grappler

i am doing a small lift on my 2013 SR5 (most likely billy 5100's @ 1.75 and 1" spacer for rear.) I want to save as many MPG's as possible from stock. Now i drive 90% highway and avg 20.9 mpgs according to my onboard computer.

I'm using my factory sr5 wheels 17" and would like to do BFG's but the the 275 BFG's are E rated and weigh 55lbs a piece.

The 285 nittos actually weigh less at 50lbs a piece. So which tire will give me the best mileage? Will the height and size of the 285 hurt my mileage more or the weight of the 275 Erated hurt my mileage more?

I know this is probably a tough question to get a sure answer on but i just want to make the best decision before i spend money on the tires.

It's not a tough question at all. If you go bigger or heavier then you will see an efficiency decrease. Simple physics.

With that said, if you do a lot of city driving, then the heavier tire will be less efficient. If you do a lot of highway mileage, then the taller wider tire will be less efficient. Accelerating unsprung mass vs aerodynamic drag.

Probably though, it will be a wash. Either choice will lose efficiency. If you are really worried about efficiency then don't lift it or put bigger tires on it. You will probably lose in the range of 10% or so so instead of 20 mpg you will get 18 or close to it. This is anecdotal knowledge from reading too many "What's your mpg" threads
 
FYI...I lost more MPGs from the lift vs the tires. Just get what you want. No matter what you do, you will probably lose about 2-2.5 MPGs according to your on-board computer (which will no longer be correct anyway, nor will your speedometer).

I'd definitely agree with these guys. From personal experience, switching to my 285's alone(55lbs on stock SR5 wheels =~85lbs per corner) accounted for a drop in milage into the 18mpg range. And on top of that, lifting can have just as much if not more effect.
The difference between the two tires you mentioned will be likely be negligable compared to simply changing from stock to either one of those two tires.

Personally, if you're not going offroading a lot, I'd go for a 275 rather than a 285. Less fuss with potential rubbing issues not going to a 33" tire, and likely lighter with a smaller contact patch to help preserve milage. Just a basic answer for you, and assumes you don't want the bigger tire look like the majority of us here.
 
The bfg TA ko 275 (e) and 285(d) are the same weight if interested in those.

The 275's in theory should accelerate better, but may not matter enough to really notice.

I just went through this also and decided on 285's because they are more standard than 275's. If you lose one a 285 might be easier to get.
 
Thanks
I know either way I will be losing some fuel efficiency but I think I'm gonna go 275s because I really can't decide if I want to lift it or just level the front out. And this is my daily driver and won't see many trails. H
 
275s with a leveled truck will look quite nice and provide great function. If you won't be doing any rock crawling trails, I wouldn't sweat it....save some money, MPGs and overall wear on the vehicle. 275s and a level should allow a nice alignment as well and no rubbing issues (maybe the fender liner). All things considered, sliders and/or descent skids are MORE important than that extra inch or so of ground clearance anyway.

Good luck and just be prepared...this will not be the end and you will want more!
 
I just bought a 2014 Trail and I would like to put some stock sized tires on it that are a little more AT type tires. I don't want to lift it, level it, or buy wheels. I don't do any heavy 4 wheeling anymore (did a ton of that years ago). I will only use mine on the road and some very tame off road camping, etc.

I would like tires that have the least bad effects on road (i.e., don't kill MPG, good road manners, quiet, smooth, etc.). Anyone have any favorites? I was thinking the Michelin A/T but maybe there are some others.

By the way, all the pictures in this thread look awesome. I love the extreme off-road look, even though I doubt that would be good for my situation. Sorry for butting in on this thread but this looked like a good place to ask the question rather than starting a new thread. Thanks
 
Stock I was getting 23 MPG, Then I jumped to 285's GoodYear Duratracs and my mpg dropped to 14-15 MPG. Currently I am using 265's BFG A/T Ko's, and I am 18.5 MPG with 90% of the tread on the tire.

I am about to off load my BFG's for something different.
 
Help!

Yeah I'm definitely confused. I'm getting a 2.5 inch lift on my 17' so I debating between the 275 BFG Ko2s vs the 285 nitto grapplers

The nittos are $180 + only 44 lbs

I found some 275 BFGs for roughly 220 but the site said 55lbs?

Mine's a street queen aka daily driver so comfort/quiet/longetivity/efficiency are most important vs off road capabilities. Most of my off roading will be expeditions so I don't need a drastic set. What would you guys recommend?

All signs pointing to the Grapplers

Sounds like you don't even need a lift in the first place and could have stuck with stock size tires so if you're already getting a lift then just go all in and get the 285's. No point in going through all this trouble to lift a car and end up running 275's when you could have done that stock anyways.

I opted for the smaller lift at 2.5/1.5. I'm not a fan of the front being so low on the stock 4runners. But yeah I'm thinking of going through the nitto 285s. Same tire on the pro (minus the 285) so it should be pretty comfortable

I'm actually dealing with the same dilemma. I'm installing a 2.5" suspension lift on my 2012 SR5 and would love to go with the 285's, but the rubbing issue seems to be a lot more prevalent with the 285's than the 275's. This is also my daily driver, so I'm very confused about the direction I'm going in.

I’m currently at 1.75” via 5100s in the front, 1” in the rear via CF spacers, and on 275/70 KO2s.

For a daily driver, this choice worked for me without any issues. Yes there was a loss in MPG but on average, I’m still at 17.8 or so.

About to go 2.5”/2” with Dobinson and JBA UCAs but still keep my 275s rather than go up to a 285. This difference to me is marginal and not worth it.

I must have written this in my younger and dumber days as I'm now running a 2.5" lift with 275's!!! LOL. I had 285's on for a bit and took quite a penalty with daily driving aspects. Acceleration, braking, MPG all took a hit. I ran them for about 14k before going to 275's and liking it much better. Much of my problems stem from living a 6000ft and going to about 7000ft daily for work. You start to notice 285's a heck of a lot more at altitude and going up a mountain. I suspect that if you are a flat lander or live at minimal altitude then 285's are fine. For my situation I would need to regear to run 285's to be happy with them.

Live and learn.
