I guess us 4X4 owners are our own worst enemy. Each person trying to 1-up the next and having to upscale tyres in the process. But it's true - gotta get the tyre that works.

285/75/17 KO3s. No rubbing noticed. Love the look and driving feel. Heck, I just love the vehicle.

And these are with stock 17inch steely wheels? No offset tweak?

Looks good @bradb622 ! No issues on the rear door?

Installed one of the spare tire relocation brackets available, works great and does not block the camera.

In all honesty, INEOS hasn't built this as a bronco/wrangler competitor. 35s are not needed for any workplace, overland trip, or other utility usage. The only place where big tires are NEEDED, are arctic expeditions etc. I had a wrangler on 35s, it looked great, but realistically never needed anymore than 33s to go anywhere.

35s with a small lift etc is still better than most other 4x4s. but ill be sticking with 33s on mine!

You're not lying. I think it's just cause I think I'll only be able to afford one new car in my life lol and it's so rare I want it to have everything... rock crawling AND towing, for example. But just like everything else... it's gotta be pros and cons, not pros and pros. BUT... I do think a vehicle that weighs as much as the Grenadier would do well with wider 35's... it's a HEAVY GIRL. 35's are the new 33's. I'll be satisfied with 33s... but do think the ability to place 35's without cutting should be built in.

It would take some real ignorance to compare an Ineos to a bronco or jeep.

I does take 35’s without cutting anything on stock suspension. Do your research on wider tires versus pizza cutters. When you air down a pizza cutter it gives a similar contact patch area to a wider tire aired down but the patch shape is different. The pizza cutter has a longer contact patch which is preferential off road. On road, the pizza cutter is substantially lighter and narrower both of witch help with fuel economy acceleration.

Adding to everything @Commodore said about pizzacutter advantages:

quieter
lighter, easier turning & better steering return (I have no desire for a steering damper now)
better wet traction
generally better snow traction
less drivetrain strain for a given diameter (rotational mass)

I would expect them to be worse in deep sand. Pros and cons, as you say, @WJG-GMT II

I tried out pizza cutters on my GU Patrol to specifically target better soft sand performance but I went back to 285s with the same 33“ diameter as I found the car a bit too „slidey“ on gravel compared to the 285s.

Along that same line of thinking, I expect pizza cutters have a disadvantage when off camber and on rocks, where the lack of width can make it easier for the tire to slip off a rock laterally. I have the DuraTrac RT in 255/80R17 which has been great in the Sierras. I’ll see how well they do in Moab.

So here in CO, where I’d more likely encounter gravel/dirt roads and rocks, pizza cutters might not be the best? Pizza cutters for overlanding?

I do think that pizza cutter look more at home on an IG/Defender, for historical reasons, versus on a Jeep, especially a modern one.

The advantage of 35’s is roll over, and sidewall depth necessary for airing down. If you want more contact patch softer rubber and a lesser load range is your friend, but at the risk of puncture. If you stuck people in the same car with 255 or 285, unless it’s a manual steering box, no one is telling the difference. It’s all placebo.

Just Get what hits that magic combo of working/fitting while making ypu happy to look at your rig.

Hi there,
Just picked up my Grenadier and I am now looking at tyres. I am looking at installing these exact tyres (same wheel design too) and wondered how they have been for you? Thank you, James.

Perfect for me (mostly paved roads and occasional unpaved roads). I have ~5k miles on the tires with no rub or modification to the vehicle. Only issue is the TPMS sensor was triggered and stayed on till about ~4k into driving…finally, it was corrected automatically.

Amazing - thank you. That’s good to hear before I get them fitted! I’ll ask the installer to take care with the TPMS side of things..!

255/85r17 Mickey T Baja AT. stock 17” steelies. Stock springs. 1000lbs of overland gear. No rub. Raises truck 2 1/8” @36F 40R psi compared to stock 265/70R17 BFGs.

And still no rub aired down to 22F and 26R psi in the sand on the stops

TCMColorado · Sunday at 9:46 PM

Mickey Thompson Baja Boss AT in 255/85R17 on the stock suspension. There is no rub of any kind so far but I have not yet flexed it to the bump stops with these tires.

I’ve just installed Falken Wildpeak AT3WA’s in 275/65 R18 on the stock 18” alloys. They have improved the stability and handling dramatically over the stock Bridgestone 255/70 R18 that came on my Fieldmaster. I went with this size to increase the tyre width but keep the vehicle height the same (https://tiresize.com/comparison/).

Falken also offer a handy tyre pressure confirmation for different weights of the vehicle. I’ve attached the standard weight vs the max axle load weights for information.

Do you have a link to that Falken pressure chart, please? (For other sizes.)

Absolutely loving my Falkens also. Mine wears A/T4W in 255/80R17 on the stock steelies. I prefer narrow for wet road and wet snow performance, based on where I drive, and as a bonus the steering lightness/return also improved.
