yes i searched, stock pro w/285s

[lewdog998]

Searched and could not find anything definitive, mostly people asking about pro wheels.

ANYWAYS,
Stock 20 Pro. waiting on Eibach lift springs (in development) and UCA replacement (when springs come) but i need tires.

looking at the duratacs in D load....one of the few tires that approves 7 inch wheel. Weight seems reasonable and load rating seems like good compromise.

Any pro owners out there that have placed 285s on their ride without lift or ucas. i am fine with fender and flap mods if required.

If you did fit 285s, what brand, spec and did you have to realign to make fit?

thanks

Brick, I did search the bar...BUT all of the results were about pro WHEELS, and fitment issues as related to rim width etc. I did not find anything on specifically addressing my specific question (fitment to a stock Pro truck, not wheels) I appreciate your effort to keep the forum clean. If you know the answer, or can direct me to the specific thread that would be great.

Just search for "285s no lift". This will answer all your questions for pro and non-pro alike.

I run 285/70/17 on a stock TRD PRO with the stock Bilstein TRD PRO suspension.
The 285s are Nitto Ridge Grapplers.
I've been running the 285s now for a couple years without issue.

Pro should have a 1" front lift compared to other stock 4Runners. I think you can fit 285's as long as your willing to trim a bit of the front bumper and push the front fender liner forward.

This should get you covered:

Going Bigger - 5th Gen Tire Fitment Guide

 

[baldrik78]

Lifting an Independent Suspension does not allow for bigger tires. The geometry of the suspension is unchanged - it will travel in the same arc and start/stop at the same points.

So yes, 285/70R17 will fit a stock TRD Pro, *but* you will have to modify the front fender liner and possibly modify/remove the front mudflaps. If you change wheels or add wheel spacers you may contact the Body Mount or the plastic cover behind the mupflap that hides the pinch weld or even the pinch weld itself.

Ahhh...makes sense....

Thank you all for your quick feedback.

Even you Brickly:

They fit

Installed the 285 70 Duratracs, load D

Fit fine...minor rub that i fixed with heat gun, no trimming required.

 

[ahtoxa11]

Looks good. The duratracks in that size and load rating is probably the next tire that's gonna go on my truck after the KO2s wear out.

Surprised you have no rub, especially with the front flaps. Mine weren't even close to fitting with the flaps on. Same wheels as you.

I have the newer fox shock upgrade the TSB where they replaced the coilovers with the 21 version. I did not take measurements before, but they definitely sit a little higher than the originals (maybe because they are new...maybe that is not even a factor). They are definitely close though.

would this work for non pro but trd rims on a venture for example

 

[Grape Ape]

Yes, you can run 285/70/17 on stock TRDP wheels and stock suspension on a TRDP itself. I did for over a year with no issues.

You have to remember that the bumper is trimmed at port on the TRDP in addition to the suspension and not on the other models, so you will have issues with 285s on a non-TRDP.

Suspension lift height doesn't matter. I'm at 2.75" front with Kings. It doesn't matter because you're 'preloading' the suspension to sit higher. It still moves in the same arc through its travel. So if it's gonna rub, it's gonna rub anyway if you really stuff the tires.

But every truck is different slightly.

Thanks for the clarification....
What is your thought on doing the eibach trd pro springs when they come out. Is there any real benefit... I see higher center of gravity and lower fuel mileage as a negative.

Fwiw...I did not experience any rubbing in this last week of which at least 2 to 300 miles were off road. Terrain was enough to hit skids on occasion.

So any benefit to raise it 1.5 inches with springs?

Not without raising the front end to the same height as a stock Pro, +1”. You could add a leveling spacer to achieve this, or maybe you can adjust up your non Pro shocks, not sure if you have 5150’s, then trimming your front fender/bumper area per the Pro as done at the port and then pushing in your fender well. I did not do this. There is a TSB out there for this mod and plenty of videos. The rear height is the same on the Pro as the other models.
I added 1.5/1” Cornfed spacers to my stock Pro and did no other mods whatsoever with my 285’s and only slightly rub at max articulation in certain situations.

 

[Gouranga]

ok so wait i know the pro is 1'' higher

but what would rub exactly if i fit 285s
the 2021 venture comes with the grey TRD wheels. but obv not the 1'' height as the fox shocks on pro i dont have those on mine but i have kdss lol

so fitting the 285s without having that 1'' height difference would rub on what exactly ? not the upper control arm i hope right ?

then what

Depends on your use case -- whether you need that extra clearance at the body. Lift will provide better approach, departure and breakover angles, as well add added clearance for skids, which means you may hit or scrape less. If you scrape a lot today or expect to in the future or you just want to reduce the chance of that, go with the lift. It will add capability and may make a difference in clearing an obstacle or not (or how much scraping you're willing to do).

I don't think 1.5 inches of lift has enough CG impact to really worry about that. It also doesn't severely impact lifespan of other parts, such as CVs and u-joints as opposed to a 3+ inch lift.

That, and it looks good, subjectively.

It will rub on the front fender down low and the fender liner. It may also rub a bit on your mud flaps if the caster is not right.
There are many of advantages to lifting a vehicle as stated in the previous post by Ahtoxa11, which, I would do if you are going 285’s.
