Advice needed: 35's not fitting so go to 34's?

[indy14]

I put on Falken Wildpeak AT4w tires (35x11.5 that measure a true 35 inches) with +35 method wheels. I haven't lifted or leveled yet. I have trimmed the wheelwell liner and removed the crash bar. The tires still rub regularly on the front, which a level would likely address, but I thought that the backs would be fine. I was wrong.

I did some mild offroading and the rear wheels articulated way too far into the wheelwell, binding up and ripping up the pushpins. Not a huge deal, but something I need to fix before I use the 4runner again off road.

So my question to all of you: Should I go down to the 285/75/17 Wildpeaks (34.1 inches) so I don't have to build the 4Runner around tires that are too big? Or should I stick with the 35's hoping that an eventual lift kit will address the issue (even though lifts supposedly don't help me fit bigger tires)? I think that a slightly longer rear control arm would help. I don't think I want a spacer kit, but would rather go with suspension that is better than stock and happens to level or lift the vehicle. I've seen vehicles with nice suspension lift kits posted on this forum but I can't find them for sale yet. I am not interested in diff drops after watching this.

I use my vehicles off road regularly and am more interested in performance than looks. I'm coming from Wranglers and Broncos and am used to being able to crawl up most obstables and rally them fairly hard. I understand that the 4Runner is not a Wrangler (for better and for worse), but I'm hoping that I can build it to be good at higher speed desert running, and still hold it's own on moderate rock crawling trails. I appreciate your feedback.

I order a collar lift from Peak and my understanding is in order to run 35s you NEED to lift it. I was curious about good articulation after tho. Wescott has videos of their beat up 4Runner after a desert event and I think they just ran the colar lift and 35s. Im thinking of going 34s just in case but I like you want to be able to use the 4Runner as it should be used.....OFF ROAD! What did you end up doing?

Amen to using the 4Runner off road!

The 34.1" Falken tire wasn't available in load C, so I pivoted to a 255/85/17. Yes, a pizza cutter. Online reviews are really good so I took the plunge even though it is a load range E.

The tire is great and doesn't rub at all in normal situations on or off the road. But get some decent articulation involved and the rear tire still binds.

So I'm back to looking for other solutions:

1 - Anyone know what tubes are running behind the fender liner of the back driver tire? If I could move those to make a bit more space then I think I'd be good. I'd also need to make more space for the back passenger tire.

2 - Install a bump stop to reduce articulation so the tire wouldn't bind. This was recommended by a local off-road shop.

3 - I want to wait for lift kits that better fit my budget and performance needs come available. I'm hoping for something like this, but obviously for a 6th gen: https://teraflex.com/2010-toyota-4runner-falcon-2-sport-tow-haul-shock-spacer-lift-system.html.

4- Any other suggestions?

The fix for this is adjustable control arms to you can move the axle back a little bit and center in the wheel arch. I've noticed that they're a closer to the front of the car from the factory and when you compress the rear suspension the tire moves closer to the front off the car as well. You could extended the bump stop but that's not the real fix in my opinion.

Do you have any pics of your 4Runner with those 255s on? I'm most likely going to try to squeeze a 285/75r17 on with a 1.25" peak front top hat spacer.

You already ran the 285/75's? You didn't have any rubbing?

Reason I'm asking is becuase my lift is back ordered and want to get going with the wheels and tires. I wasn't sure if 285/75's with +25 offset would work with stock suspension.

If anyone has done this and wouldn't mind passing on their experience. Just curious if there was any rubbing.

Thanks

I'm planning on a 1.25" peak and a 285/75r17 with a 17x7 et25. You need your wheel width to properly calculate where the wheel/tire will move within the wheel arch.


I should have 43mm more inner WHEEL clearance and will extend by 17mm.
My tire should be 20-30mm wider so divide in half and add to the inner and outer wheel measurement.

That exceeds my knowledge of tire science. The fact that you have gone through these calculations and are planning to use the same size components as me makes me feel confident that they will fit.

Thanks.

What wheels are you going to use and what make/model tire 285/75r17 are you wanting to run?

Black Rhino Awols 17x8.5 +25 offset

Looking at the Toyo Open Country A/T III LT285/75R17 C load

Westcott Preload Collar lift. A few weeks until it arrives though.

I prefer to go with 285/70r17 for weight, but I think they will look too small with the 2.5” lift. I like the look of the 285/75 from the pics I have seen.

The wheel specs on these are actually +25 NOT +35. +35 would be inbound by 10mm. But that setup will have some poke and rub at factory height. If the wheel didn’t have so much offset it would probably fit.

I’ve seen that build and have been using it as a reference. I understand it’s a +25 — I saw his correction.

Just to confirm: you're saying a +35 will have some rubbing at factory height, but a +25 will not?

Either way, I still plan to go with the +25 for the look. If rubbing is expected with the +25 at stock height, I’ll wait the 2–3 weeks for the lift.

Thanks for your help. My research strategy is to learn from what has and hasn’t worked for others. Your knowledge and assistance are appreciated.

Thanks again!

No problem. It can be a lot of work to fit a large tire with minimal lift. Especially if you haven’t done it a bunch of times.

A +25 is going to rub at stock height With a 34. That’s just my opinion. +35 would be easier to fit since they would fit inside the wheel wells more. There’s a sweet spot in there for sure. 8.5” wide +25 offset needs a lift.

Got it. Thanks again- this was a huge help.

I really like the +25 so I just have to decide on a few things before I move forward.

Can anyone tell me if I can get away with 34" tires (285/75r17 falken wildpeak at4w) with no rubbing or cutting? the wheels are 30mm offset black rhino

We need to know the wheel width. Without it offset doesn’t matter.
