Trying to sort out wheel offset versus wheel spacer blocks

[Mendoncyclesmith]

Okay, so I'm inching closer here, and ran into a goofy snag.

Found these locally, and they were so cheap I couldn't ignore them. Off a 2022, same bolt pattern, and only driven for one summer, so no salt damage at all. $250, all 4, with lug nuts. :cheer2:

They're 17's though.

The whole tire mire makes my head spin.

I just want raised white letter. 16" I can find plenty. 17's though? It's like they cease to exist.

I wanted Cooper AT3 XLT's, and after playing with the awesome tire size/offset calculator 96 RedRunner posted, I went from thinking 285x70's to 285x75's.

That too, messed things up. I can find the 70's in 17 white letter. but the 75's, no dice. Looked at All Terrain T/A K02's, ditto for no white letters in 75.

Am I crazy???:hurt:

So, any and all suggestions for a 285x75xR17, white letter, tread with side knob, along the lines of the above mentioned options?

Google refuses to easily let me search for tire size + raised white letter, and just gives me junk links to Walmart or wherever, and lots of 16" versions, not 17's.

Educate me please, I'm all ears.

Also, after all that, I also looked for 255/85/17's, which would be a great version of the slightly taller and skinnier tires I'm seeking, and only one tire exists?

There's also a Falken on line, but Falken no longer lists them on their site, so I'm assuming they dropped it.

Yokohama seems to have one, I'm chasing it down.

Yes, not white letter, gah, I'm driving myself nuts.

I believe in a 17” wheel it’s 255/80 not 255/85

255/85 is mostly 16s and 255/80 is for 17” and have slightly less sidewall to make up for a slightly larger wheel

How much are you planning on clearancing? 255/85R17 and 285/75R17 are 34 inch tires

 

[phattyduck]

Educate me please, I'm all ears.

If you aren't going to be cutting up the body, stick with metric 32's (265/70-17). Those tire sizes you list are quite large...

If you are going to clearance the body and front bumper, then you can go bigger on tire size.

Okay, sorry everyone, yesterday was mid "WTF" time, I've now spent a few more hours, and come to a better understanding. I'm not ignoring the helpful responses above, just jumping ahead to my final answer, that I'd appreciate any thoughts y'all might have.

Gave up on white letter.

Seems 17" wheels really limits choices, why Toyota uses it as a stock size then, no clue.

Any rate, what I wanted, and mentioned a bit earlier in this thread, was taller and skinnier.

In 17's there's literally one tire that achieves this, and that's this fella:

https://www.tirerack.com/tires/tire...5QR7BBAT&vehicleSearch=false&fromCompare1=yes

The video below goes into more detail than I'll bore you with, but this guy has similar lift to me, his is 3" suspension to my 2", and mine is actually a tad taller overall with spacer blocks.

35" Pizza Cutters on My FJ Cruiser - New Mickey Thompson Baja Boss AT 255/85R17 Tires - YouTube

And below is a screenshot of the size comparison, current tire on the vehicle, to the Mickey Thomson.

The video also shows where he got rubbing on the inside rear of the wheel well, so I now have a visual understanding of where, which helps me picture how I'd resolve the rub, but I think this tire, will actually pull farther away, there, and the height, am I crazy? I don't think the height will impact me at all.

Am I on the right track? At this stage, I'm happy to deal with whatever the results are, but I think I can run this with no wheel spacers at all.

 

[Mendoncyclesmith]

Just figured out how to measure wheel offset, and these 2022 4Runner stockers, are 124mm from mounting surface to inner rim edge.

Simply adding that data point.

“I don't think the height will impact me at all.”

Tire Height isn’t really an issue with these trucks it’s the width that kills them. I ran 255/85 on stock suspension and the clearancing was very simple and easy. Took about 10-15 mins per side hitting the firewall and trimming the front bumper a bit.

Like how people with 285s usually do new upper control arms and spacer and all that. 255s you don’t need to do any of that, like I said I ran them with totally stock suspension

White letters are throwing a wrench in the decision for you it seems.
Changing wheels I wanted tires to be same location they came from.
I marked them with a enamel paint pen so tire guy would know.
No precleaning a lite swipe with paint figured it'd wear off. 8 months later
Could barely tell a difference, it took comet short stiff bristle brush n elbow grease.
Alcohol precleaning doing it with purpose could get you some options.

Hey all, I've played around at this already to some extent, but I've decided that I'd rather just do what's proper, and I cannot get straight answers from anyone, it's always "bolt it on and see, then deal with the issues. :faint:

96, total combined lift, 4.5" front, 3.5 rear. 2" suspension lift, then spacer blocks to level the front end out, but the 2.5 in front was too much, so I had to add 1.5 out back. Level now.

Are the 'spacers' you are talking about suspension spacers or body lift? If not body lift, your total suspension lift in the front means nothing for tire clearance - the suspension travels in the same arc no matter its starting point.

Clearance is highly dependent on wheel offset, tire width and what your definition of 'fits' is... so there is no such thing as a straight answer to this.

100% stock, no other changes, metric 32's are the biggest you can go.

As soon as you open up hammering, cutting, welding, etc. you can go up to about 35's. The farther out the wheels go, the more F/R wheel well clearance you need, the farther in the wheels go, the more you have to worry about upper a-arm and frame clearance. Bigger tires also mean more chance of breaking other drivetrain parts, re-gearing, etc.

The white lettering thing is a bit odd requirement - but DIY painting is always an option, which should open all the possibilities you may want. (there are plenty of Jeeps with 17's, so there really shouldn't be tire choice limitations)

Not sure if you are actually looking for feedback and information, or you're just wanting someone to tell you it will fit. Suspension lift changes ride height not the arc that the wheel travels during suspension travel. A 2 inch body lift doesn't equal 2 inches of tire clearance either.

 

[Endlessblockades]

Off on a bit of a tangent but related to the OP question.... does anyone happen to know the offset and backspacing on the factory 16" aluminum (5 star) wheels? I can probably dig it up, but this thread has attracted some knowledgeable members. I am running the 5-stars with 1.25" Spidertrax spacers all around. This places my current 265/75 tires right at the edge of the Limited flares which I like. I would like to move to 17" rims and approximate this width/geometry using the rims alone (and go to narrowish 33s).I'm trying to add up the numbers as well as overcome my considerable ignorance on the subject. Might make a Black Friday move, but I don't want to buy something because some wheel MFG site says 'This Fits Your 2000 4Runner'. TIA

Checking the 4th 5th Gen forums might help you with that 17's became the norm.

Bad Luck:

Sorry, I get it, and sort of yes, sort of no? If someone here had specifically fit X, Y and Z together and could say, "yes, that'll fit"? I'd be super happy.

Shy of that, you guys have been amazing, super patient and helpful, and it's appreciated, I know my approach is a tad wordy and unconventional....

White letters:

Purely a style desire, I'm 55, I always liked them as a kid, I know it's not currently trending though, even more so in 17" tires, so I'll have to just walk away from that, as a more aggressive tire that fills the wheel well better, is my end goal. I made a mistake buying the passenger rated Coopers I did, and they look anemic on the truck. A buddy jokingly told me to just paint pen the letters if wanted them so badly too, 96Red, so yeah, I know I'm being a wanker on that one, and your experience on that has been noted. :boink:

Phatty:

So, 2" OME suspension lift. Spacers are nylon blocks under the rear coils, an nylon pucks at the tops of the strut towers.

I'm sorry to be clueless, but what that is called, body lift or something else, I am unaware. Educate me as time and willingness allows, you've given me a lot of time over the last couple years, so thank you.

If my buddy is correct (I measured yesterday) the new 2022 alloys are +15 offset, same as my stock steels. He has zero offset wheels on his new Bronco with 35" K02's's and no other mods. Apples to oranges, not comparing the two, but those wheels allowed bolt on fit *for him*.

So I'm grasping things, slowly....

I'm also coming to grudgingly accept this maybe a bolt, on and discover I'm without a truck till I resolve the as yet unknown issues.

Hammering back the fender well, I can do that. Hoping the narrower Pizza Cutters will reduce that too. And yes, what I consider acceptable, is now on my list of things I comprehend. My old 31x105 K02's did zip something but only in an extreme move, and I lived with it, that may be in my future again.

Now to find someone local who can source these tires for me. I prefer paying cash, and as a small, local business owner, I vastly prefer to keep my dollars local, too.

THNK YOU TO EVERYONE, your help is invaluable to someone like me. :thumb3:

You give me too much credit...:laugh:

The tiresize.com calculator was helpful, as I posted.

This is like handing a screwdriver to a monkey and being surprised when he stabs something with it instead!

Info is only good for me if I understand how to apply it, and E10, 3 ply etc, may as well be Greek as I thought all these were 10 ply tires (see what I mean?).

Wish I had hours to spend reading and the brain power to crunch the info into usable formatting, but I learn far faster with my hands than my eyes, and I just accpet that about myself.

still have to do your part. Read.
I've stabbed my finger with a screwdriver before a few times in fact, we've all been there.

The extra spacers you have are a 'spacer lift' - which isn't ideal. With that much total suspension lift on stock geometry, you are only good for looks, not actual performance. As long as you understand that, its ok. It will also put a lot of stress on your front ball joints and axles... A body lift is spacers that go between the frame mounts and the body, which leaves the suspension/drivetrain the same but lifts the body out of the way. There are pros and cons to that also.

Also, BFG K02's are available with white lettering in specific sizes. 265/75-16's are one of them (metric 32's for the stock wheels). As your lift height, they might look a bit small, but would require 0 other mods. The America's Tire website will let you search by size and white lettering to help you find what you want.

A forum member named p nut posted this about 5 Star 16" rims in 2008 if anyone's interested: Seems the backspacing is 4 5/8 (4.625").

 

[96RedRunner]

[MENTION=373697]Endlessblockades[/MENTION] goes hand in hand with what's been said are best numbers to look at for 3rd Gen's.
4.5" BS O offset 8" width 16" dia, different BS will have a different offset.
SCS Motegi have run both and fake beadlock steelies numbers are legit.
