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.
