Can ChatGPT give the correct answer? Well, sort of. I asked it about proper tire inflation. Here is what I got when I asked: “How much air should I put in my tires?”
🚗 Where to Find the Right PSI
Look for a sticker:
-
Inside the driver’s side door jamb
-
Inside the fuel door
-
Or check your owner’s manual
It will list the recommended pressure in PSI (pounds per square inch).
📊 Typical Tire Pressure Ranges
Most passenger vehicles fall into these ranges:
-
Sedans & small cars: 30–35 PSI
-
SUVs & crossovers: 32–38 PSI
-
Pickup trucks: 35–45 PSI (can vary more if towing or hauling)
⚠️ Do not use the PSI number printed on the tire sidewall — that’s the maximum pressure, not the recommended setting.
🌡️ Important Tips
-
Check pressure when tires are cold (before driving or after sitting 3+ hours).
-
Tire pressure drops about 1 PSI for every 10°F temperature decrease.
-
If your TPMS light is on, inflate to the recommended PSI, not “until the light turns off.”
If you tell me:
-
Your vehicle year, make, and model
-
And whether it’s front, rear, or all tires
I can give you a more exact number.

From Roger:
If you have an travel trailer, ChatGPT missed you folks, as the proper inflation for your trailer is shown on the Certification label on the driver side front end of the trailer.
ChatGPT also did not give Class A RV folks the correct answer, as your inflation label is near the driver’s left elbow inside the RV.

Why would anyone trust AI for safety-related questions? It’s akin to telling a toddler, “here, hold my gun”. What could possibly go wrong?
Ask a generic question, you get a generic answer.
