GX550 Aftermarket Wheel & Tire Thread (4 Viewers)

Hey Guys - I’m looking for advice on wheel fitment for my 2025 GX OT+ (stock suspension, no lift planned).
I’m set on ordering Volk Racing ZE40X, but I’m torn between:

• 18x8.5 +20
• 18x9 +35

My goal is a flush look without excessive poke, and most importantly I want to avoid any rubbing (UCA, Wheel wells, fender liner etc.). I plan to run 275/70R18 AT tires, and if it’s realistically possible without rubbing, I’d consider 285/70R18.
For those who have tried similar setups on a stock 2025 OT+, which wheel size/offset would you recommend and why? Any real-world rubbing/clearance feedback would be greatly appreciated.

The +20 offset will stick out close to 10mm more than the + 35.

I previously had a 285/70/17 on a 17x8.5 +18. See attached.

My current set up, see few posts above, is pretty much flush but my wheels are half an inch narrower than what you’re looking at with the 18x9.

Depending on what you want to use your vehicle for, the 285/70/18s biggest downside will be the lack of light weight tire Options (no SL rated tires) So you will take a hit in ride comfort and mpg if that matters. A lot of people look at the Falken Wildpeak C rated , which weighs something like 68lbs per tire compared to 275/70/18 options that can be had around 45-50lbs in an SL. Disregard if you’re actually doing some off-roading.

The other thing is that you may have difficulty stuffing a spare back there in a 285 tire if that matters.

So no lift, no rub? Any wheel spacers? This is a very similar set up I’m considering but don’t want to add a lift. It would be awesome if this fits with the stock ‘25 OT suspension.

No lift, no spacers. No rub at all

Hello everyone, I want to change the 22-inch wheels on my GX Luxury+ to 20-inch ones with AT tires. Could you suggest the wheel size so they don't stick out beyond the wheel arches. Maybe someone has photos of such wheels on this car. I've already read the whole forum and got confused.

Hey! Happy to help!

Update - swapped my 305/70r17 tyres out for 35x12.5r17, did a quick walk around for anyone wanting to know exactly how I made them fit: cheers

Just swapped out the standard 22" wheels for a new winter wheel/tire set. I went with 20 x 9 Niche Vice wheels with a +30 offset, wearing Bridgestone Blizzak DM-V2 tires measuring 275/55R20. The ride is very smooth which I expected over the lower profile stock tires.

 

[gloomy700]

Can you send a photo of how this looks on the car?

 

[MrAce5]

I've been lurking here for a month or two.

We powder coated the premium wheels and put on nittos.

Very happy with the outcome

I’m scheduled to powder coat mine in black as well. Are those in gloss black or matte? Can’t tell from the pic.

If anyone wants some stock premium+ inspiration

Is this a 2024? I’ve seen 2025+ owners claim you can run this setup on stock suspension with no rub

I've heard a lot of different things. What i think comes the closest is this westcott designs video ,

i honestly have no idea how others would make this tyre fit on a stock gx550 with no rubbing or trimming. Even with a levelling kit some claim this tyre set up needs no modifications or trimming... Again not sure how that's possible if we're talking about a true 35" x 12.5" tyre. To give you an idea I first mounted the wheel/tyre on the car before i did any modification or trimming and could not turn the steering wheel at all as it was hitting at the front liner and back bracketry in the wheel well.

 

[Wmflyfisher]

Are you running same size for spare? what modifications did you do?

Did not change spare. Removed crash bars that’s it.

Has anyone installed the OZ Rally Legend 20-inch wheels on their GX 550? Would love to see pics. Tire Rack has them with a +45 offset.

GX2.0 (traded my '24 for a '25 - another story) finally got new shoes this weekend...

Peak Performance 1.25" spacer in the front to level her out.
18" Icon Recon Pros w/ 40mm offset.
Falken Wildpeak AT4w 35x11.5r18, Load C (34.9" dia. x 11.9" wide @ 62.6lb).

"Crash Boxes" unbolted and removed from behind the front tires.
Minor rubbing in the front which required pulling the fender liners forward about 1/2" (drilled new holes and remounted) and a VERY small trim on the corner of the bumper to line up w/ the new position of the liners - easy peasy and looks OEM but will likely replace the front bumper anyway over the winter. Full flex test w/ a forklift and no rubbing or clearance issues inside the wells whatsoever.

Looks amazing. Rides great. Very little poke (basically flush).

Discount did the install and alignment, which took quite a bit longer than normal due to the pins.

Love the wheels (satin black looks so much better than the matte black Methods I had on my '24) and the bead lock 'innovation' is slick. A lot of hate on Falken tires out there, but this particular size is a Load C w/ decent weight specs, and boy are they smooth - I generally run Toyo AT3s, but this is my second set of Falkens and I'm thrilled with them so far, just as I was with the first set.

What is your MPG like with your setup and how many miles on tull tank of gas?

I really don't track MPG (never have). That said, I get around 300mi per tank, so what's that, around 14mpg?

More like 17 MPG since you only get to use roughly a little more than 17 gal as the other 4 gal is reserved for the fuel pump. You won't use the whole 21 gal unless you run it until it stops which can be bad.

MrAce,

Not much help to you. But I’m using the O.Z Rally Desert, 18x8, +25. From Tire Rack / Discount Tire. Very high quality build, but not forged so it’s a lot heavier than most on the forums here would ever want; understandable. It’s a bit more heavy duty..which I’m good with for towing. I feel like I can beat on it with no worries. I’m using some NYTOP metal hub rings to ensure perfect mounting. Absolutely gorgeous wheel in person.

I strongly looked at many high end forged wheels, but couldn’t quite get a look I really wanted for the $$. So went this route. In the future I may relegate this to winter duty..we’ll see.

dang i have 275/70r18 SL tires and my total average is 14.7 mpg and i dont drive too hard. my dash shows 250 miles when i fill but have 2-3 gallons left after click. I used to get 270 miles when i was at 15mpg.

i see people only get 200 miles per tank on 35s, how do you do get 300

Tires look awesome!
