The test right now is Floyd Hill westbound. All the construction has the road completely torn up, then at the bottom there’s a pothole field all around the hard left turn.
KO3's!!!

I’ve run mine at 46 PSI. Discount set them to 33 when I first got them and I hated how floaty it felt. The amount of sag in the sidewalls just didn’t look right to me, so I started some research on E Load Tires. Lots of people saying that they’re designed to be at a higher PSI, and running to low is putting too much heat in the sidewalls and risking a blowout. I reached out to BFG and was initially told in the 45-50 range. I got a follow up email that 46 is probably the sweet spot.
It’s brutal through there. Since August I’ve been out to Grand Junction twice, Keystone, Breckenridge, Moab and Vail. That stretch is always the worst part of the entire drive.
Just a quick update. I managed to visit Discount before they closed. The tires were not properly balanced. One of the red-shirts took the LC for a drive around the parking lot and immediately noticed something was off. He also looked at the tires and subjectively mentioned the profile looked off at the current pressure...meaning it looked rounded? Afterwards a young expert came and told me the fronts were off by 1.5 oz's and the rears were at 2.5 oz and 4.x oz respectively. I had no idea what all this meant other than contemplating these numbers should be as close together as possible in the lowest possible range. The young expert nodded his head and said ideally these numbers should be at 0 but if you have it around 1 or less, it fits the margin of error. The pressure was also lowered to 40psi from 46psi. On my drive home, I was able to notice less vibrations, but topping out at 45mph probably is not enough. It still wasn't as good as the OEM tires and the street roads are reasonably good. I'll do more tests tomorrow on the highway and different streets at 40psi (current pressure) and ~35-36psi. If for some reason I'm one of the unlucky few that struggles to get balanced KO3's, my next options are the Nittos and Falkens at the 275/70R18 size....maybe even going the SL route.
It is. I’m afraid it’s going to be that way for a while as they rethink that section of highway. Pretty unnerving with no shoulder on either side if you’re next to a semi.
I calculated that in 23 years of driving I’ve driven over 450,000 miles, and that might be the worst section of any road in the US that I’ve driven. Freaks me out every time I go through there with my family and we’re stuck in a pack of cars/next to semis.
So, for those not in Colorado reading this - there’s a section of I70 just west of Denver that is probably the most dangerous piece of interstate highway in the country if you’re heading westbound.
It has everything - you lose a lane to a merge at the top, then there’s a ~2 mile descent down a 6% grade with a 90 degree hard left at the bottom to avoid a cliffside. All at interstate highway speeds on a major shipping route full of semis. Where it snows a lot.
Right now CDOT has the whole thing torn up as they figure out a better highway approach, which means that in addition to the above there is no shoulder on either side and the road surface is awful.
I have been doing some reading about what is the correct psi to fill the 265/70R-18s KO3s "E" load tires on my 2024 LC and I am no more clear than when I started reading about it.
Costco set the tires to 46psi and from talking to the employee who fitted the tires, he said that is the proper pressure for "E" load tires, the door jam in my LC was for SL load tires that came with the vehicle from the factory.
I spoke with BF Goodrich and they did not have the 2024 Toyota Land Cruiser in their system but did have its stablemate the Lexus GX550 in their system, the person at BF Goodrich said that the Lexus GX550 should be set to 45psi.
Folks on this thread have set all sorts of pressures from the what the door jam sticker recommends to 48psi and a bunch of pressures in-between which leaves me very confused.
What is the proper pressure to 265/70-R8 BFG KO3s to on a 2024 Land Cruiser?

The engineers of the Landcruiser engineered it to run on Standard Load which would be 33psi. When you start adding in not stock size tires and non stock load tires it turns into a bit of a free for all. It then comes down to what works best for the owner and application.

Probably 35 psi. You need to know the weight of your vehicle and look at the tire pressure required for that weight. Unless you have a weigh station handy, just assume a 50/50 bias front and rear and use the tables at ( https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf )
Using page 27 of the document shows that a psi of 40 would be for a load of 2155 lbs on that tire. Do you ever drove around at 8600 lbs total weight? ( ~2150 x 4 ).
Ride at 35 and air up to 40 when your hauling bags of ready mix cement in the back. Any psi over the table given value for your weight results in a rough ride, uneven wear, and no benefits.
I have an 2500hd and use 55 psi in the backs unloaded, 75 psi for max gross weight (hauling sod/ towing trailer).
BFG KO3 275/70 R18
Initially when 1st installed, America’s Tire put 45 psi all tires. I did adjust it down to 38 psi. It is sweet spot for me…Last trip, on 15 FWY to Utah, I tried up to 95 mph (oops over speed limit 80 hahah), all was great
Happy LC to all

Agree with 37-38 cold which becomes 40 while on the road.BFG KO3 275/70 R18

I’m on 275/70 R17 for reference
I took your advice, new KO3s today, very smooth, went 44psi cold. I find ride very close to factory tires.

I'm down to 18.7 MPG running them at ~ 42psi. I am doing a lot of remote starts and I have been driving the girl around and idling when she's shopping so burning some that way. I love these tires in all respects except for the MPG.
I'd be tempted to try the Toyo Open country AT III as that is a much lighter tire with excellent snow performance or if the KO3's ever come in a standard load.
It's just that the KO3's give me the exact performance I was looking for out of this truck.

I've run KO 2's on all my Jeeps. I loved them and they just flat worked. I wanted to move to the KO 3 for my LC but just didn't want to drag around another 100 lbs in extra weight between five of them. I went the Toyo OC ATIII for that exact reason. I only have a few miles on them but they seem like a solid choice.
I am curious that how much more and less ground contact we can get from the E-rated tire at different psi? Even pressure at low 30s the tire seems to work . Should I even bother to lowering down the pressure when driving in snow or sand?

These sidewalls are very robust, still airing down just a little made an appreciable difference. I'm thinking 39PSI for the Winter.
Yep. 265/70 KO3s on my 1958. 5k miles. All great.
I couldn’t find anybody did a chalk test with KO3 on LC. Would be very cool to find out what is their conclusion
