Who's lifted a 5th Gen 4Runner?

[Corbet]

I’m very familiar with that guy. Agree with his findings. It’s too bad tire options are not nearly as good in 255’s. And I’ll admit it, the OEM tires are already tucked way into the fender. Wider just looks better. Plus according to the chart above 255s are harder to fit. Which also surprises me as it seems like the problem lies with width when you're turning. And skinny should be easier?

On my FJ the 285s rub on the frame. The 255s don't on the 4R (basically the same sus & frame)

@Runnin on E

In your opinion will 285s fit with just a leveling? No rubbing?

 

[Runnin on E]

My FJ has a 2" Toytek and they (285s) rub slightly on the frame. It never bothered me, I still wheeled it that way. Just get the 285s and run it. If they rub fix it. You will like the way it looks and "it's better to look good than to feel good"

I really wish someone made a 255/80r17 snow tire.

Well it’s an AT, but I haven’t been stuck yet!

I run 255/85-17 Toyo Open Country R/T Trail

Less about stuck and more about stop. If I drive from the house down to the road with my ATs on my LC250 in many places I’m just along for the ride. If I have my snow tires on I’m in control. We need dedicated snow tires where we live.

After all the help here, tons of 4Runner forum (not really useful) and tons of YouTube videos (Tinkers, very useful) I think 285’s with a 1/2” spacer (yields 1”) to level it is the plan for now. With the stock wheels (17x7.5” +15mm offset) it should clear 285s without cutting.

I can’t wrap my head around why the TRD Pro wheels are only 7” wide. Bumping them out 11mm with the change in offset is desirable but could still cause clearance issues. Maybe they did it to discourage 285s as the narrow width drops them out of spec for the larger tire? 255s are in spec but then that would negate the extra stance width in offset.

Down the road I think I’ll point him into a 2” front 1” rear lift to maintain max articulation and road manors. Probably Ironman foam cells.

Found a used 285/70r17 BFG to use as a spare and mounted it on a wheel I had laying around. Backspacing matches the OWM 4Runner wheels. I’d say I’ll do some test fitting but I also picked up a set of new snow tires (285’s) so we are pretty committed. The spacer kit should show up Monday.

It has been years since giving thought to this sort of thing but I think I remember a couple of arguments for a narrower rim than tire manufacturers would recommend. The first and more obvious reason is that the rim is better protected by the sidewall. Second is that it might be harder to pop a bead. I have no clue if those thoughts have been debunked in the last 20 years.

Toyo Open Country WLT1 snow tires.

I’ve been running these on my LC250 now for a couple years and been really happy so no reason to deviate on the 5th gen. Wish they made them in 255/80r17.

The open lug design handles deep snow and shoulder seasons into southern Utah before the summer tires get swapped on. I’ve had two pretty bad spring mud experiences and the tires did as well as any AT on the 250.

Coming into this discussion late. But I have 285 70 17's Mickey Thompson Baja Boss, on vixen. 2019 4Runner.
I have NOT done a BMC, and I have approx 2.5" lift. (I say approximately because even with upgraded coils she's a heavy steel laden truck, and then when you air down you lose a bit as well). I kept the oem fox shocks up front, and had the coil overs upgraded for weight & height. Yes, I'm aware they may bottom out, but I've not had any issues, yet. I have the Toytec Aluma Boss 2.0 on the rear with XHD coils.

I have the SPC adjustable UCA's and I request that the alignments get pushed forward as much as possible. I've also never needed to remove the stock mud flaps up front with that. I find the on-road & off-road driving very sturdy with this setup, even though they (the alignment guys) said it wouldn't be as good. I've driven this setup for years now & I've liked it.

Along those lines, before my last shock rebuild last fall, I considered upgrading shocks. And after this wheeling season, I'm considering it more now, because there's a droop happening on the driver's side. I have about 70k miles in total on this setup. So it might be time for an upgrade.

I scheduled the 285's to go on Monday with an alignment to follow. Sounds like I should request to have the wheels push forward as much as possible.

Make sure you talk to them about it if you have the SPC's. I think that's the only UCA that is adjustable like that. Otherwise, you may experience body mount & fender/mud flap rub.

Rocking OEM UCA for now.

Mud flaps can go. Assuming the heat gun will make an appearance.

Installed the Cornfed Suspension 1” leveling kit today. IH8IFS. That sucked pretty bad. KDSS made it worse. I learned a few things but don’t look forward to the day we put a full lift on it.

Stink bug is pretty much gone.


Test fit a 285/70r17 on a proper matching offset wheel




No rubbing on level ground. I got it about half stuffed using a ramp on the opposite corner. Clearance was the same. I did pull the mud flaps. Full set of 285 tires are getting mounted Monday morning then an alignment.
