In the tire comparison table above, you can see a detailed calculation of the size difference between 255/90 R16 and 195/100 R16 tire. The calculation results are presented in the form of visual infographics, on which tire with size 255/90 R16 is on top, and tire with size 195/100 R16 below. Both in the table and in the graph, the tires are compared according to the following indicators: overall diameter, section width, circumference, sidewall height and clearance. Also, the online application calculates the difference in real speed and speedometer readings if the difference between tire 255/90 R16 and tire 195/100 R16 is significant.
If you want to compare other tire sizes, then select their sizes in the drop-down fields and click on the green button. The online wheel calculator will then display the new results.

What do you think about them?
I just ordered some 33’s ( 255/85r16 Falken MT ). And I don’t have the cash for the mod$ required ( or recommend ) to run the 285’s properly.
I’ve read I can fit those Pizza Cutters without rubbing.
I have a 2017 OR on 2” lift ( Eibach stage 1 ) with stick wheels. And I do have some added weight with skids, armor, bumper and winch so I’m not convinced I’m even at 2”.
A 255/85R16 is 33"x10", so it's not super super skinny and is pretty tall. I test fit one on my truck (2" Fox midtravel, Camburg upper arms) and it looked to me I'd still need a cab mount chop to fit with my 3rd gen 4Runner wheels (about 3.
75" backspacing, 7" rims). I have not lowered my bump stops.
But I could see with some finesse by the alignment guys and the right wheels (OEM 4.5" backspace seems like it might be better) all that might be needed would be some quality hammer time to the fender pinch seam and almost definitely trimming some plastic. It'll also depend I assume on the tire's actual dimensions. BFG tends to run under size, for example.
One worry you might not be considering is the overdrive. A 255/85R16 is going to give you about 8% to 10% more overdrive compared to a 265/70R16. It almost bumps 1st gear into 2nd gear range. That's part of what's holding me back from going larger than 265/75R16, the truck already is geared too tall and doesn't like to crawl without stalling more than I like.

Way back when I did a mild build on a Taco and ran that tire size.
I did have a 2" lift.. really loved all aspects of the tall/skinny from a traction and handling standpoint. Definitely added grip in the snow, less junk flung on the side of the truck an added bonus, thought it looked cool...
The gearing though as @DaveInDenver mentions is real. Slower off the line, hunting for gears going up hills, probably lost 2mpg in efficiency. I equate it to riding your mountain bike in the middle chain ring all the time, if you're old enough to remember when bikes had front sprockets. Anyway, it did look good.

Thanks for the input guys.
I’ll post after I get them on next week.
Of course, this is just a step in the eventual process that leads to a CMC and a regear and even larger tires. And on-and-on.

I've also been thinking about going to 33" pizza cutters (I would be doing 255/80r17 probably since I have 17" 4th gen t4r wheels) when my current 31.
5s wear out. Just watched a really good video on them earlier today actually. The only downside is losing mall crawler points it seems which I'm fine with.

Also it's a big misconception that lifts help clear tires unless you are just talking about street driving where you won't be dealing with full stuff.
Highly recommend going through this guy's videos, he really tears apart so many myths that abound with IFS vehicles.

Thanks for the videos.
I’m REALLY torn up about loosing my mall crawler status though 🤣
Nice technical videos.
Basically, my skinny tires ( installing Wednesday ) and my small 2” Coilover lift ( Eibach Stage 1 ) are a powerful combo. I’m feeling pretty good about my cheap / practical build for decent off-road performance.
Though I still can’t compete at the mall.

I mean you have to be made of gobs of money to compete at the mall so no point in trying. But yeah it's nice how much modest gear gets you plenty of flex on the trail without stressing your front end too much on the IFS and killing milage. I'm actually going to lower my front end a tad bit when I get rid of the cheap setup that has a spacer lift up there. Still trying to decide whether I want a 5100+ome 881 or am ironman foam cell pro coilover so I can rebuild it.

between those two choices, I would look into a basic OME setup. I am personally not a fan of the 5100s. I have had them, they were ok, but there is a lot of stress that get put on a tiny clip that holds the spring perch on, and I have seen people complain that those fail from time to time. As far as the Ironman kit, I have seen mixed reviews.
Here is the OME kit, and this page gives the option of the SPC UCA. While you don't HAVE to have it, it will allow the suspension to be correctly aligned once you change the geometry with the lift.
Buy once, cry once.

Having dumped money on 2.5" FOX suspension I'd second just straight up OME nitrocharger stuff. You'll get 90% of the performance for 33% of the cost.
Use the savings on gas and beer. It's about experiences, not gear. But you already have Eibach, so that sort of implies you have something decent. Eibach springs is what FOX used on their factory assembled coil overs when I bought mine. I've since gone to King springs but only because they were available in my diameter, length and rate while Eibach was out of stock at the time. Depending on the diameter of your springs I'd suggest maybe a FOX 2.0" shock as an alternative to OME or Bilstein or otherwise, but only because OME shocks might not fit your Eibach. Not sure the diameters are compatible.

I don't have an Eibach setup currently. It's just Monoroe Quick Struts with a top hat spacer that seems to be giving me 2.5"-3" over stock depending on the measurement standards I've seen floating around for stock on 3rd gens.
I actually have decided I want to go down to about 2" to gain more down travel and less stress on front end stuff.

Why is so hard to find these things not in a full lift kit >< My rear is great, just need to refresh/upgrade the front. Also how to you set the preload for lifting with the Nitrochargers? Do they have spacers that go on the perch on the shock body?

My mistake, I was thinking of the original poster with respect to Eibach. I'd stick with the OME recommendation in your case. My starting completely stock measurement was 20.5" roughly and now my front has a static ride height of about 22.5" from hub center to fender lip.

You can't adjust them per se. The way ARB does this is they sell several different springs with varying lengths and spring rates to set your payload and ride height. Suffice to say you have a starting target of weight that's measured I think as stock as baseline and if you add some amount you go up to compensate.
The rate plus length determines how much weight the spring can hold up with your limit being what's known as the blocking length, which for a coil is when it's fully compressed and the coils touch. Beyond this you will damage the spring or the truck, e.g. you risk breaking the control arm or coil cup from the frame.
So what a longer spring does is gives you more length to compress it. So it starts 14" long and fully compressed it might be 8.5". If it's more-or-less linear at 650 lb/in that means you have 650 * (14 - 8.
5) = 650 lb/in * 5.5 inches = 3,575 lbs of force to hit blocking. If the truck has 2,000 lbs of effective curb weight on that corner then you have 1,575 more lbf to go for more cargo or dynamic force and it will sit with ~3.1 inches of static compression at rest.
The shock's travel length and the suspension ratio (wheel travel to spring/shock travel) are important. The wheel travels further than the shock by the ratio built into the control arm geometry and the actual force at the wheel is reduced compared to the shock. I think for our trucks the relationship is slightly less than 2-to-1.

Well I just gave Slee a holler and I think that really helped to simplify things for me and turn me away from the idea of a coilover and towards the full OME setup with 2.5" lift springs. Little bit pricier than the billstein + OME option but it sounds like I get a simple worry free setup that should last quite a while and have a good solid ride on and offroad. Going to sit on the idea probably for a few more days but I think that's my endpoint for this.
Too bad my current 31.5" tires have plenty of life left in them though, really liking the idea of grabbing some 33" pizza cutters eventually.

Here are the pizza cutters installed.
Positives
——
It sure fills out the wheel well better. Plus the mud terrain aggressive look.
If the videos above a true, my build is a good combo of budget and capability for the 3rd Gen OR.
Negatives ( expected )
——
Louder on the road. Lost 1.5mpg.
When I take a left turn and hit a speed bump or storm drainage gutter on neighborhood roads I’m rubbing at the back of the tire. I just need to trim some plastic.
Unknowns
——
I’m going to get flexy this weekend and see what happens. I haven’t tried I-70 yet.
Looks awesome! Good job.
I would paint the sliders gunmetal or black. No offense, just my opinion.

In the table above you can see a detailed comparison of the difference in dimensions, parameters and characteristics between the tire with size 195/100 R16 and tire size 255/90 R16. The results of the calculations are also presented in the form of visual models (infographics), on which the tire with a size of 195/100 R16 is on top, and with a size of 255/90 R16, respectively, at the bottom. The visualization was generated in two projections: lateral (left) and frontal (right). The online calculator compares tires according to the following characteristics: diameter, width, circumference, profile height, revolutions per km, ground clearance change. Additionally, the potential deviation between the actual speed and the speed displayed on the speedometer is calculated, which can occur if the difference between the tires is 195/100 R16 and 255/90 R16 is significant.
If you want to compare other tires, just select the required parameters in the drop-down fields and click on the green button.
