Going Bigger - 5th Gen Tire Fitment Guide

[Rickybob6y]

Thanks

Coming from the jeep world tire fitment is not a big deal, but just wanted to stay for all the post and putting this together. Helped alot. stayed with stock 265/70r17. Milestar MT

Thanks

Super helpful post that probably took a ton of time...thanks

Read through the majority of this thread and seems like the consensus is:

If I have a 2017 4Runner TRD Pro and use the stock rims and suspension, I should be all good with no rub with BFG KO2s in 275/70/17.

Am I crazy?

Leveling 2015 trail premium for bigger wheels and tires

Hi guys, new member and new to the 4Runner scene. Have had a 2015 Trail Premium for about a year now for the wife's daily driver. I am wanting to level it mainly just to add some bigger aftermarket wheels and tires/for looks. Hopefully I'm not beating a dead horse with this, but I had a few questions about it as I'm new to Toyotas. I was trying to decide whether to go with just a spacer kit for a front end level, or something like the bilstein 5100's. I believe I'm going to get the bilsteins as it's probably the better option. But I also don't want to spend a ton of money to level the 4Runner for bigger wheels and tires, as it is just her daily driver and won't be going off road all that much..

I am wanting to run 18x9 Grid GD5 wheels (Pictured) with somewhere around a +15 offset. And like a 285/60/18 or 275/65/18 all terrain tire. Probably cooper st maxx or nitto terra grappler, maybe toyo.

1. Will this setup fit in the front with 1.75" or 2.5" leveling on the 5100 bilsteins, without rubbing, or minimal trimming?..
2. Will I need anything else besides just the bilsteins? Aftermarket upper control arms, Front diff drop kit, etc?..
3. Will anything need to be done to the rear suspension to fit this setup? Matching 5100 bilsteins? Or coils that provide more lift, etc?..

Thank you for any insight, appreciate it guys!

my insight is that those wheels look terrible

Well thanks for the insight, it helped immensely. To each their own I guess...
I don't think they look too bad myself, and it's the ones she wanted on her car. She picked them out lol

Well I thought I had this figured out by looking at the guide on the first page and reading thru a good amount of this thread. But the backspacing has got me somewhat confused, and reading 1engineer's posts about a lift not necessarily making a big difference with regards to rubbing has me questioning things again.

I plan to purchase a 2017 SR5 4x4 in the next few months, and my plan was to get the TRD wheels. I wasn't aware before this thread that they had a different enough backspace than the SR5 or Trail wheels to make a difference.

What I am trying to understand is will there be any rubbing on an SR5 with the TRD wheels and 265 or 275 tires. My plan is to also get the Burtman 3/2 lift, which I thought would all but put the rubbing concerns to bed...but I have since learned that's not necessarily the case.

Thanks for any feedback, and looking forward to joining the T4R club soon.

Leveling questions for bigger wheels and tires

Welcome to the forum [MENTION=152204]JP307[/MENTION].

Check back in with specific questions after that (if you have any) and people here will likely be more responsive.

Hi [MENTION=141503]carlos.elmotor[/MENTION], thank you for the reply and the link. I have read through basically all of this thread and several others as well. But I am still somewhat confused about what all can fit with a leveling kit and bigger wheels/tires, and what all is needed.

From what I've gathered I believe if I understand correctly my 18x9 wheels with a positive offset, and around a 285/65/18 tire should fit with minor modifications like possibly trimming the fender liner etc.

My main questions I still have are:

1. What setting is completely level on a 5th gen, the 1.75 or the 2.5? (Seen many different answers)
2. And will I need anything besides the bilstein 5100's for leveling? Like aftermarket upper control arms, etc?.. At the 1.75 setting are you ok with the stock UCA's? At the 2.5 setting do you have to upgrade them?..

Thanks for any insight, appreciate it guys!

I'm having the same problem. "Lift doesn't help" is an odd statement for me coming from trucks and jeeps my entire life.

I bought this 2010 with 265/65 street tires on stock wheels and SPC UCAs (don't know why, but I assume it had a lift). I bought 1.25 spacers and this is how I want the vehicle to look when "finished", but I don't want to continue using the spacers. Ideally I buy wheels with the correct offset.

I have a 2" lift on its way, but after reading and reading I'm learning the 285 ridge grapplers I want may, or may not fit even with the adjustable UCAs and the lift. Well shit. I'm not very keen on cutting the mount but I have zero problem cutting the plastic. This seems very iffy. I don't want to buy wheels or tires without knowing if they will actually work. Nor am I certain what offset and tire size is idea for the look I already explained ( flush ).

I know this has been discussed over and over, but it's hard for me to wrap my head around the lift and adjustable uppers having little effect on the use of larger tires on this damn thing. I love the vehicle but it's not very mod friendly in this department it seems (might work/might not). Never had any of these problems with trucks or jeeps. Makes me want to send all the parts and leave it stock (yuck). /annoyed

Any rational help would be appreciated

Thanks,
Jon

What specifically would you like to know?

 

[RIjon]

What specifically would you like to know?

If I understand correctly, height doesn't help (to an extent of course) because the shape of the wheel well on the front of this vehicle is narrow and deep. There is also more room inside the opening making the lip of the fender the narrowest.
So when you take the body mount and fender lip into consideration (liner isn't an issue), you end up with a specific area to which the wheel/tire can move throughout its range without issue.

Depending on the offset of the wheel, wheel size, tire size, and adjustability of the suspension components, you can fit ___x___.


I'm frustrated with ___x___. I don't want to buy parts that don't work.

Thank you for reading

Sorry you are frustrated.

1. Lift will help fit bigger tires, but only at the lifted height. When you go offroad, your suspension will compress through the original non lifted height so if you rub at stock height you will rub when lifted and your suspension flexes. This is fact.

2. Any wheel/tire combo that pushes the centerline of the wheel/tire AWAY from the 4Runner will increase the chance of rubbing. So wheel spacers, wide wheels and high offset wheels mean you will have to do more trimming. This is fact.

3. If we both bought identical 4Runners on the same day from the same dealer, you might be able to mount 285's on stock wheels and have no rubbing. If I did that I might rub. Why? A) The 4Runner has tight clearances for tires, when fully turned or fully compressed. Some 285's might only clear by 1/32" in either of those conditions. Tight. So how could yours fit and mine rub? Your alignment spec has tolerances for the caster setting. Anywhere in the tolerance is fine for alignment spec but it makes a difference because caster basically moves a tire forward a bit. In addition to that the 4Runner is a BOF construction, just like the Jeep... or a Suburban. There are also manufacturing tolerances that could stack up - or not - against you or for you. The Jeep is designed to have wide open wheel wells. The 4Runner or Suburban or even the JGC is not. Try fitting 2" larger diameter tires on a JGC or a Tahoe stock. Probably won't work without modding either.

Now, modding to fix your rub running 285's, should you have one, is not hard at all. Each item below might work on it's own or you might have to do multiple items below, depending or wheel and tire selection.
1. Move fender liner forward (10 minutes)
2. Trim front bumper cover (an hour)
3. Trim or remove mud flap (10 minutes)
4. Have caster setting increased by alignment shop (1 hour)
5. Body Mount Chop (BMC)

I built the chart based on these factors. If you have a problem with uncertainty then I would keep stock wheels and stock size tires. You should be able to go to 275's with stock wheels (or another wheel with stock wheel specs) and have no rub. You MIGHT even be able to fit 285's on a stock vehicle with no rubbing (keeping stock wheel or stock wheel specs on a new wheel) if you are lucky. If not, you just need to start with #1 above and work your way down.

So, is there a clear (as can be) verdict if there will be rubbing on a new SR5 with the TRD wheels and either 265 or 275 tires? I'm sure it's hidden somewhere in this thread...but I haven't yet come across a confirmation.

As mentioned, I am either going to get the Burtman 2/1 or 3/2 lift, but wondering about rub without lift based on 1engineer's comment...

"Lift will help fit bigger tires, but only at the lifted height. When you go offroad, your suspension will compress through the original non lifted height so if you rub at stock height you will rub when lifted and your suspension flexes".

Thanks

265 will not rub with those wheels. 275 might. What part are you having trouble with?

Regardless of lift or not, the suspension has the same geometry. It still has to move along the same arc or plane when it flexes. So to keep it from rubbing, you have to make sure it won't rub at full flex, at rest and everywhere in between. That means if you put on tires and wheels with no lift and they rub, then they will rub when you lift it and the suspension moves back to the stock position during flex. I don't know how else to put it.out:

Thanks for the confirmation and comments...definitely helped school me a bit. Your chart clearly shows 265 and 275 in the GREEN for 17" wheels...I was just unsure how much difference the offset of the TRD wheels -vs- the SR5/Trail made with regards to potential rubbing (lift or not). Now just need to hurry up and purchase this thing and get going.

lifting education - Thank you!

I really appreciate you (1engineer) giving your time to explain these details. Thank you! T4R's are totally new for me - looking to learn before buying.

My questions: 1) Best link on here for learning/researching lifting LIMITED T4R (2017)
2) Your opinion - 2017 LIMITED or TRD PRO? - Can 2017 Limited be lifted 2-3" easily by professionals or no you're better off going TRDPRO if you want to lift. one or the other has better lift options etc? A specific tire is not a priority, functionality and of course the look is.

Background: I've lifted my 09-2500HD and YES learned the hard way about wheel size, rubbing, offset and honestly only enough to know I need professional help. So I've been reading as many links here as I can and would appreciate your opinion.
Thanks,
Mark

For anyone curious: i replaced by stock dunlops with Cooper ST Maxx 255/75 17s.

I'd always been curious as i found very little information on their true size (mounted or not). Just measured mine in the garage, on the vehicle. It right around 30.75-31" Stock dunlops measured right at 30.5" in the same spot. so they are ever so slightly taller. I was very close to getting the 255/80s, but the extra weight and e-rating scared me off.

As noted in reviews, they are very quiet for AT tires. They are slightly louder than the originals, but that's to be expected. Mine balanced right out. They also handle more light AT tires. Steering is lighter, a bit more "flighty".

Checked my speedo verses the waze app on an iphone and my garmin 60scx gps. Both now show the speedo only being 1mph high at 70mph.

I'm happy, i was looking for a tire a bit taller than the OEM, but keep the speedo correct (as can be), the ride compliant and my gas mileage (will see, but from the looks so far, it's fine).

Will it rub?

I have a 2014 4runner sr5 i am going to put a 3.5' toytec lift on it, trd rims and 285/70-17 tires on it. Will i have rubbing? Will i need to cut? Thanks for the help!
