And that sticker on the door jamb? I never ignored it again. Neither should you.

I pulled into a servo. The digital pump was broken, so I grabbed the old analogue gauge—the one that looks like a pen with a slide rule. I had no idea what number to aim for.

I opened the door. There it was, a little white sticker, baked and peeling but legible:

Feeling like a genius, I set the pump. Beep. Beep. Click. The tyre filled. The car lifted. The steering went light again.

Here’s the story within the story: I learned that week that under-inflated Jazz tyres cost me 4% more fuel. But over-inflated to 40 psi? The car felt like it was on ice skates. Hit a pothole, and you'd feel it in your teeth.

It was a Tuesday, 3:00 PM, and the Australian sun was hitting my 2007 Honda Jazz like a magnifying glass on an ant. I was parked outside the Woolies, sweating through my shirt, just trying to get home. The steering felt... heavy . And the car was pulling left, subtly, like it was trying to shake hands with the gutter.
