Default Tire Pressure Wanring Light ON - Whats Wrong?

Hello Mates, My car started this about 1 week ago, when I wake up a car in the morning that warning light was on then after couple minutes of riding it went off, PSI is similar.

nowadays warning light won't go off, it's always on, what could be the possible cause? sometimes it shows the yellow square warning on rear right tire too.

Do you always keep them at 30 psi? I'd bump those up to 35 or so. 30 is low. I believe somewhere around 30 psi is where the warning comes on.

30psi is pretty low. it should be at 36 cold. And up to 38-39 running.

They're all say 30, but if you check with a psi meter, you'll probably see that the highlighted one is at 30 or closely below it. It happens a lot in the morning during colder seasons. Once you start to drive and heat builds up, it'll fill up more and go away. However, it is best practice to keep the recommended air pressure in the tires especially during colder seasons.

Keep recommended tire pressure - it helps with both - gas mileage and tire wear.

I think the recommended tire pressure is 36 all around. It's better to keep it at least at 36.
