37 PP - What Pressure Are You Running?

[maxr]

@Kyle761 how do you like the 37 grabbers. Need a 37 STUDDED (edit) winter tire and that seems to be the only option

I love my grabbers! But I haven't took them out in the snow. But what I've heard they don't do "well" in the snow because of the large grouping of the tread, (they are technically mud tires). Wish I could give you more info, but for everything else they are a really great tire. Although its really hard to get a set in. I'm currently waiting for a spare and its been about a month. Warranty work......

The stock BFG All Terrain KO2 37x12.5x17LT 116S did fairly well when running in Snow mode from Jan to April but we get a lot of ice and i live in the forest on a steep (13 to 18% grade) road and studs are a necessity. too bad the BFGs can't be studded

The general Grabber A/TX looks similar to the stock BFG ... do you have the A/TX or X3?

I’m at 36 front 35 rear

This is where I was planning on going. See how it felt and how the tires wore.

I was at Raptor Assault a couple weeks ago, for the 37s they were running 32 front and 28 in the rear.

That seems slightly low for the street but with the larger volume maybe….

That seems really low, but I would suspect that is because they aren't really being used on the street. I'm headed there in a few weeks, so I'll see what they say when I'm out there.

See if you can get them to comment similarly to the image below. I grabbed this of the thread I was using for my Gen2.

38F/34R looks about right for me....

Just out of curiosity because I don't yet have my truck, how low can you run without throwing a low pressure warning. Is that something you can disable natively or can you change it with a tuner/forscan?

On my Jeep, I have a tuner where I can set the minimum pressure (down to 23, I believe) or just disable TPMS altogether. Which is what I do when I air down at the trailhead. When I turn it back on, it returns to the pressure that I programmed it too. I keep mine at 25psi.

At least 30 because I just ran them at 30 on a trail and no warning came on.

Yes, 2nd that. Probably for off-road around 30 is the number. For street, this would be way too low.

Run my 37 KO2's at 40 all around

If this is from a gen 2 thread, it is not relevant for Gen 3 .. we have a 5-link rear. I have been doing 70-80mph on forest service gravel roads and not experienced rear axle hop but then different roads will have different surfaces especially it there is a lot of rv traffic. I am sure ford did more shock valve tuning from gen 2 to gen 3. I'll agree 40 is high for the rears if I was pre-running in the desert but for when I am driving 80+mph on a paved rural road and then transition to a gravel road, 40psi works just fine for me in MT
