285/70r17 on stock lift

Can i put 285/70r17 on stock lift on my 2018 T4R?

 

No
Technically, yes. But
You won’t be able to drove it

 

With enough cutting you could likely get away with it, on road only, with stock wheels, and no wheel spacers.

If you don't plan on cutting or lifting don't go over 275 with stock wheels.

Switching wheels makes it even harder to know for certain. Offset and width can make a 265 tire rub.

 

No but....

You don't have to go crazy either so let me throw out a couple of options.

Stick with a 265 but get a more aggressive tread like a BFG AT or even MT. Your Runner will look a lot better.
Add some wheels spacers. I had wheel spacers with my stock suspension and tires and no rubbing.

Go up to a 275 in a nice AT or MT and again, you will get a slight increase in ground clearance and your Runner will look great and you wont have any rubbing.
Add some wheels spacers. You can probably do so without any rubbing and based on my limited experience I would be surprised if you do but I can't promise anything.

Go up to 285 like you really want and add a small 3" spacer lift like the Toytec FJ3-RSP - Toytec Lift / Leveling kit for FJ & 4Runner- Works with XREAS. That's what I did. With my 1.25" Spydertrac wheel spacers I had to trim the inside edge of the front bumper, remove the front mud flap and make sure it was aligned with as much caster as possible using the factory control arms. Now, if I try really really hard and turn hard left in reverse and then brake I can get the edge of the left front tire to just barely rub the left body mount. I can't get the right side to rub.

It can be done.

As mentioned earlier, you will want stock wheel offset and backspacing to keep rubbing to a minimum. That being said, even with the stock wheel specs, you're probably going to need to push your caster up to 4*, push your fender liner forward, and trim a small corner off your fender flare....but that's easy stuff. There are threads around that walk you through that. All you need is a screw driver and a box cutter.

If you're doing any sort of serious off-roading with this set-up, you'll drive the tire into the top of your fender liner, which is where a lift will help avoid that.

But how you offroad will determine your lift height. If you do full articulation rock crawling stuff, a 3" lift will suit you better. If you do mild trails, you could get away with a 1"-1.5" lift with 285's. I have 1.5" of lift up front with 285s and haven't hit the fender liner with my tires. I'm mostly doing mild trails, but have also done some fast, desert style off-roading with good sized bumps and whoops.

Are you opposed to lifting it for any reason?
