For those with 285/70/17

My 285s on stock Trail wheels barely kissed the fender liners, not enough to feel or hear but enough to see the rub marks. Once I put the spacers on I had to push the liners back, trim the bumper and remove my mudflaps.

Do you feel like you needed the Spacers? I bought some but after talking to some guys local they are telling me I dont need them and just to send them back and save money.

They weren't necessary at all, I just wanted a more aggressive stance.

...Good luck - you don't need a 2.5" or 3" lift to add these tires, but even if you did that you would still need to do items 1 and 2 above. You can leave your 4runner stock and run this size by doing these 3 things.

I'm running an Eibach Lift Kit with springs and shocks , approx 2.5-2.75" at the most up front, maybe a little less with my Warn bumper. General Grabber ATX 285/70R17s on OEM TRD Pro wheels. Didn't need to modify anything...No fender liner, no bumper nor mud flaps. I do get a slight rub when full locked on my mud flaps if I'm backing up on my inclined driveway or of course in a tight turn with articulation which is not even a concern, but your items 1 and 2 are definitely NOT needed with the lift you mentioned. Maybe that's just my set up, but it's unnecessary. :D

Did you have issues with getting it aligned? I’m being told that they can’t get the Caster in specs so I’m most likely going to have to get UCAs now....

Nope, mine isn't in-spec. Fortunately the alignment was so bad before I started that even with bad caster it still drives better than it did before. I'll probably get UCAs at some point, but I won't be in too much of a hurry unless I start seeing some funky tire wear.
 
OP: as many have stated before me, the extent of trimming will depend on your specific vehicle. Some have had to trim fender, do UCAs, BMC, etc. and some haven’t. I’m one of those that did not have to trim.

This.

Not all 4runners were built equal. Not all 4runners respond the same to the same lift. Think of 4runners responding to lifts like finger prints -they'll all respond just a little bit differently.

So, whether you'll rub or not with the bigger tire, you have no clue until you actually try it.

I'd suggest laying out out a plan where you don't redundantly pay for 3 or 4 alignment jobs. At $150/alignment, after a few of them, you might as well have bought a lift or better rims.

p.s. I'm on 285s and only rub the front splash guard and body mount at full articulation in reverse. Doesn't bother me enough to do the splash guard mod or cut the bumper. I just go easy or try to reverse the other way lol

There is a guy in FO running 295/70/17's with a 2.5 lift and he has no rubbing or any issues. I have noticed that 295's are cheaper than 285's also. Just a FYI.
 
I seen multiple threads on here that you can run 285/70/17's stock, if you don't plan on hitting tough trails. Just do the finer liner mod and remove the mudflaps and you should be good. But every truck is different.
 
Nitto RGs 285/70r17 on FN FX Pro wheels 17x8 +0 on stock suspension required mud flap removal, doing the TRD Pro port style bumper cut/fender liner mod in order to work without rubbing.

What is the Trd Pro port bumper cut? Tried to look it up...no luck.
 
[MENTION=307558]baysta[/MENTION] thanks for clarifying.

Although, brings up the point, I am confused with this is TRDP specific, these are all the same parts, dimension-wise. They even show a Barcelona Red 4runner in the TSB, there are no "red" TRDP's in 2015 apart from Inferno that is more like orange. Only the red one has TRD skid too. :shrug:

Anyway thanks for the link :)

No you can do it on any vehicle, all I was saying is that they cut the fender/bumper at the port for the pros. I just assumed everyone knew the pros came with the cut already applied, which is why I referred to it as the "pro cut". If you want to go to the dealer, they can refer to this TSB to do it for you for like $60, which is 30 mins of labor, or you can do a similar cut yourself at home if you're handy.
 
I got your point :) Sure of course you can. Yeah never really bothered to check anything 2014+ or TRDP specific in all honesty. Apart from some cool colors I think they're way over priced... and well I bought a '13 because as goofy as this gen is overall, I disliked the refresh even more. That said, the fender cut I linked certainly improves the goofy aggro front a bit and you certainly won't get any fender rub from that :D

Seems straight admission they designed the thing to run on Duelers without thought of ever putting on even a stock sized AT.
 
I have a 17 TRDORP and put on Wildpeak 285/70 r 17 tires last month. Here is what I had to do - as others have noted 'it depends' on what steps you have to do.

1. Fender liner mod - move it forward. This takes about 15 minutes to do both sides. You will need to do this.
2. Trim bumper - this sounds way more difficult and scary than it actually is. Before you move the fender liner forward you'll notice it is somewhat lined up with the bumper. Once you move the fender liner forward the bumper will have about an inch or so of trimming that needs to occur so your new tire doesn't hit it. Do this before you get your new tires.
3. Mud flaps - I used a heat gun to 'push back' and reshape the mud flap. In all honesty for my 4runner this step wasn't necessary because I had no rubbing coming from the mud flaps, but I had the tools and did it anyway.

Once you do all of this you will either be happy with the way your new tires look or you won't. For me it all came down to the stance of the vehicle. I felt the tires looked too stuffed so I put Bilstein 5100's all around using the stock springs. The fronts were set at .85" and somehow the rears got a slight increase in height with the new shocks. It sits perfectly for my taste now.

Good luck - you don't need a 2.5" or 3" lift to add these tires, but even if you did that you would still need to do items 1 and 2 above. You can leave your 4runner stock and run this size by doing these 3 things.

Thank you for sharing your setup! I also have a 2017 TRD ORP with Bilstein 5100s, but mine are 1.75" front with 1" cornfed spacer in the rear. I'm keeping my stock wheels. I have been trying to decide on 275s or jumping up to 285s, but I don't really want to do a BMC. I don't mind modding the bumper/mudflaps/fender liner.

Based you your experience, it sounds like I can probably run the 285s without having to do the BMC, which is music to my ears! Of course I know that all vehicles are slightly different and my experience could be different.
