ChatGPT Suggests Tire Pressure

[mepperson641]

New to trails. New to Jeep. But I'm a tech guy, so I asked ChatGPT (AI) " I have the standard tires on my jeep Gladiator Sport. For driving on trails, what are the safe tire pressures to run to make the trail ride smoother? "

Got this reply. Thoughts?
For driving on trails with your Jeep Gladiator Sport, lowering your tire pressure can help provide a smoother ride and improve traction on uneven surfaces. Here's a general guideline:

1. **Mild Trails (Dirt Roads, Gravel)**: 20-25 PSI
- This pressure is suitable for relatively easy trails with loose dirt, gravel, or sand. It helps in smoothing out the ride while maintaining control.

2. **Moderate Trails (Rocky Terrain, Light Mud)**: 15-20 PSI
- For more challenging terrain with rocks, ruts, or mud, reducing the tire pressure further can improve grip and allow the tires to conform to obstacles.

3. **Heavy-Duty Off-Roading (Deep Sand, Mud, Snow, Rock Crawling)**: 12-15 PSI
- On very rough or technical trails, such as rock crawling or deep sand, lowering the tire pressure to this range can provide maximum traction and a smoother ride over obstacles.

### Important Considerations:
- **Avoid Going Too Low**: Going below 12 PSI can risk the tire bead coming off the rim, especially if you're not using beadlock wheels.
- **Reinflate After Off-Roading**: Once you're back on paved roads, it's important to reinflate your tires to the manufacturer's recommended pressure for safe driving.

### Equipment:
- **Portable Air Compressor**: Carry a portable air compressor to reinflate your tires after your trail ride.
- **Tire Pressure Gauge**: Always check your tire pressure with a reliable gauge before and after adjusting.

These pressures are general guidelines, and you might need to adjust slightly based on the specific conditions of the trail and the weight of your vehicle.

A word of caution, AI uses open sources available to gain it's info on a subject.
It has no way of differentiating good info from bad info.

With that said, if you are going to go on a trail and lower your stock tires to 12-15 psi, make sure you have another vehicle on the trail with you.

I would not advise going below 20 psi on factory tires.

The wheels are the big problem. They aren't designed in any way to help hold the bead.

I think it's spot on with my practice, which is informed by 30+ years of off-roading experience. Nice work, ChatGPT!

I'm running stock rims with 12.5" wide 35's on both of my Jeeps and have never had a problem running 15psi, although I've only done that a few times on the most difficult trails . Narrow rim/wide tire combo is known in some off-road circles as "poor man's beadlock". Of course, I'm not advising anyone to do anything. Just sharing my own practice.

i can assure you my $70/ea quadratec steelies aren't designed in any way to help hold the bead either, and i routinely run 18 on dirt and 15 on sand with zero issue, and I am not gentle on my mojave when i hit the dirt. let's just say i paid for hydraulic jounce bumpers and I'm going to use them dagummit.

Isn’t that just info you could find with google? ChaTGPT really seems useless most times.

This is spot on, and anyone who plays with a commercial AI tool should be aware of this.

Every question you ask, every assumption in your question, and any information you provide to assist in getting a better answer automatically becomes incorporated into the AI "learnings". So, don't give personal information and if like me, you work in proprietary software, don't offer any specifics as to what your software does. With that in mind, these tools can be a really great way of consolidating multiple articles and other web inputs to give you a pretty good idea of the consensus answers. But also remember, a consensus of idiots will yield an idiotic answer. So, due your own Due Diligence!

Here's my take on the chat AI stuff - accuracy, sources, info found on the internet/forums and so on -

And that covers a whole lot of stuff you read on forums and fakebook..........I can think of a couple very specific Jeep-related examples.

AI is only as good as the programmer who coded it. The best ones can be a ways out there in left field.

Arnold warned us about going down this path back in 1984.

The wheels are the big problem. They aren't designed in any way to help hold the bead.

Never run the sport tires, but between 2 JLs and my JT we've run everything from stock 33" ko2s, 33" falkens, 35" ko2s, 37" Yokohamas, 38" Patagonias, and 39" kanati mud hogs all on factory wheels. All aired down to 12-15psi regularly with ~150k miles between them. Narrow wheels are less likely to debead. No they aren't beadlocks so single digits will lead to burping air on obstacles and eventually losing a bead but I've never had an issue on any combo at 12psi. It's just not a thing unless you're hitting obstacles at high speeds.
