Rub or no rub - consolidated tire upgrade review

[emmantik]

Edit: I wanted to clarify. I would like to gather real world data on how a 275/70/17 fits on stock suspension across all 5th gen packages. I would like to know whether or not they rub or don't as various wheel manufacturers make the same sized tire slightly different as tread could be wider and or thicker in depth.
__________________________________________

Hi all! I've been a forum reader for a few years but not one to post much. I've had a 1st and 2nd gen 4R and currently on my 3rd 4Runner, 2015 SR5 w/ 3rd row, all stock. I DO NOT want to abuse this ride as it is my first brand new vehicle, family hauler (3kids) /daily driver commuter. The most I want to do is go with bigger tires, yes, just for "the look!" Also, some cheap interior/exterior diy mods, but that's besides my point. I was reading the "5th gen tire fitment guide," and have come to the conclusion that I could go 275/70/17, with no rubbing, based on the chart. BUT UPON FURTHER RESEARCH, it looks like there are mixed reviews to the above depending on which 4Runner package and which tire make and model you go with. IE, KO2 275/70/17 will rub on a TRDP but not on a TE (just for example). I wanted to start a thread that lists which tire sizes will rub and won't rub, all in one. This list would be a thread based on real experience. It would be a list/thread that looks like this.

KEEP IN MIND, THIS WOULD BE FOR THOSE THAT WANT TO KEEP THEIR RIDES STOCK BUT WITH BIGGER TIRES. (Me included)

For example; this is all you would post,

Before tire upgrade
4Runner - year, base/SR5/TRDP/TE/LE
Tires - make/model
Rims - size/make/model
MPG

After tire upgrade
Tires - make/model/load/size
Rims - size/make/model
Performance
-sound/noise, acceleration, mpg
RUB? YES or NO
yes?
-mods to accommodate;
-leave? lift? liner? remove mud flaps? etc.


This would need the input from owners who have gone through this to provide the real world data. This should minimize the amount of posts regarding this topic as well.

Let me know what you guys think. I'm just trying to help others out and also myself without being roasted online.

Who wants to be first to to help?

I am really interested in this as well. My Trail arrives potentailly tomorrow and I am not ready for an all out lift. I would like to have bigger tires and upgrade the wheels. But I don't want to be like the big ass trucks in my area that all have definete rub issues.

OP, I appreciate you starting this list but if you dove a bit deeper into your research you would realize why the chart is purposely vague.

Have you ever wondered why wheel alignment is adjustable and there is a wide range of values for each setting? It's because of stack up tolerances. When you design something, especially something as complex as a vehicle suspension you have dimensions and tolerances on everything. With that said by the time you add up all the tolerances you could be plus or minus quite a bit. That's why things like headlights and wheel alignment are adjustable.

What this means is you and I can buy identical 4Runners with sequential VIN's and put identical oversize tire on it and I could rub and you don't! The caster setting could be different enough to cause that!

So even though everyone was meticulous in their documentation here one guy with a high caster setting won't rub and another guy who has no clue on his setting does.I have done a write up of this but it is buired in a thread somewhere. Your method would get closer than my chart but it would still be a crap shoot. Lastly based on history if your thread goes longer than one page many just wouldn't read it and ask a will it fit question even though your thread had a close answer. Hope this helps and we appreciate the effort!

1engineer, I totally get where you are coming from and my goal was not to take any value away from your thread/fitment chart. I find a lot of value in it and it gave me a good starting point for my tire upgrade research. I understand why you left the chart purposefully vague. But it gives a great starting point for those who want to do research. At the end of the day other owners should realize that this should only be a guide and not set in stone. And that following your chart and any info on this site is done at the owners own risk. (one would think this is common sense).

I believe there are a lot of 4runner owners like me who appreciate their rides the way it came out of the factory and who aren't looking to heavily modify their vehicles. I say again, this is my 3rd 4runner and all were stock, except my 1st gen which I bought with 33's. And it seems like in a lot of forums other users get roasted for asking the same old questions, tire upgrade fitment to be a common one. Some people just want to do their due diligence before dropping a thousand or so dollars on a new set of wheels. And I'm pretty sure some get intimidated for posting "Noob" questions, me included. Then you get the generic, "did you search?!?!" response.

I know this won't be 100% accurate, as you mentioned above their are a lot of variables and adjustable settings involved. But hopefully this list would supplement the info in your chart and get 5th gen owners a step closer to making an informed and accurate decision when upgrading their wheels/tires since this info would be based on real world applications and experiences.

Again, this is for those who want to keep their rides stock but with bigger tires, without rubbing. If they want to know about other variables, there are other threads for that.

So to all that have upgraded their wheels, please help out the other owners. Thanks!

All this is going to do is give you misinformation. What will fit on one truck will not fit another... they are all a little different and people will claim they fit when they really don't at full compression flex.....

So read the tire fitment guide and the other related thread http://www.toyota-4runner.org/5th-gen-t4rs/208403-changing-tire-size-wheels-read-first.html

You will be able to get 275s to fit without issue (no rubbing on metal), but it might take a little minor tweaking (alignment/fender liner/plastic trim). If you are not willing to do that minor adjustment... YOU REALLY NEED TO STICK WITH THE STOCK SIZE TIRES.

Formulas that have worked for others is not a bad idea.... but you have to read them as.... OK it worked for this exact scenario, on this particular day, with..... which is not my truck.... Better approach is to know the boundaries and how to adjust your way to be within the acceptable range.

Yes I understand that one brand of tire might fit one vehicle and the exact same tire won't fit another, I get that. That's not my point. I'm just trying to get real world data from other owners on what 4Runner package they have, which tire make and size they have upgraded to, and whether it rubs or not. That's it! It's not that complicated.

For example;

I have a 2015 SR5,
Upgraded to KO2's 275/70/17
Stock rims
No rubbing

Or

I have a 2013 Trail
Upgraded to Duratracs 275/70/17
On stock wheels
Minor rubbing

These are just simple examples. That's all I'm trying to gather. Simple.

But we can answer that without a bunch of noise. They all fit 275s.... Some will say they did nothing and it just worked. Others will state they had minor rubbing until they did an alignment, pushed the fender liner forward and trimmed the plastics of the bumper cover a bit..... None will have had major rubbing unless something was really screwed up.

Not that the info would be horrible..... It will just end up being a bunch of slightly differing stories. Maybe some pattern will jump out with a specific combo though. I guess it is worth a try.

 

[emmantik]

Yes this is what I'm trying to get. I read on another thread that KO2's on a a TRDP will rub but on a TE it won't (being the same size). This is the stuff I'm trying to get at. I wanna gather this info for other owners for future reference. I would like to gather how each brand and size fits on base models, SR5's, LE's, TRD's and TE's, for the very reason that the same sized tire would fit different on each model. This is the information I'm trying to gather. And I say real world applications from real owners would be the truest info.

 

[emmantik]

There are many tire makers out there, many sizes for each and multiple different package levels for each 5th gen. There is quite a number of combinations available and I'm t trying to consolidate all for future reference. We did not have as many options with earlier gens so I think our information/data should expand as well with each gen.

I'm pretty sure that has to do with the wheels, not the tires.

May be mistaken though.

I have stock size tires, but they constantly rub the pavement...

275 ko2 stock trail wheels no rub 275 - 6 offset rub body mounts a lil and you will have to cut liners and remove small mud flap on front

Seems like we are beating a dead horse here. I'm with [MENTION=66316]1engineer[/MENTION] that we have a pretty thorough tire fitment thread. Well, actually TWO.

The Pro should not be considered on a stock suspension because well.... it's not. Regardless if it comes that way from the factory... it's still lifted albeit slightly. If you want to put different tires on your truck and you want to make 100% sure they don't rub.... buy the stock size. No ifs, ands or buts about it.

Thanks! What package 4Runner?

 

[emmantik]

I wanted to clarify. I would like to gather real world data on how a 275/70/17 fits on stock suspension across all 5th gen packages. I would like to know whether or not they rub or don't as various wheel manufacturers make the same sized tire slightly different as tread could be wider and or thicker in depth. Because when I search how 275/70/17 fit, I am getting mixed reviews depending on package, TE, TRD etc.

It's not beating a dead horse and yes we already have a great guide. But there are mixed reviews on the 275/70/17, some say it rubs, some say it doesn't. It seems like it depends on the package (TE, TRD etc) and tire manufacturer. This is what I'm trying to gather. Different tire makers make the same sized tire slightly different, like tread width and depth.

 

[CatskillsRunner]

You have to bring in alignment numbers if you are considering this. If you rub and how could be dependent on your alignment. And aftermarket ucas or not. Otherwise you will be missing lots of info. And this still doesnt address the fact that all vehicles could have subtle differences.
