How often u guys fill the tires air?
 

so today my car's tire pressure light goes on.
And I only have it for 3 months.

I might take it to the dealer to check later after my work.

Is this normal?

Very rarely, maybe once a month? Maybe they put it to 32 PSI instead of 35 PSI.

I never did lol

yea, I never did it on my old cars too.
But now the brz's air pressure light goes on, and only three months.

this makes me feel worry about the tires.
Hopefully not anything happen to the tires.
>.<

Maybe check for a nail

No need for a dealer trip, buy a gauge for a couple bucks at an autoparts store and fill 'em up at the next gas station stop, check in a week or two, if they're dropping pressure quicker than that then go to the dealership. Unless of course you enjoy going to a dealership service department to have them fill your tires up with air, is that complimentary? I can't even guess.

Also remember that tire pressure can vary with temperature, you can fill 'em all up even to 35 psi in the morning, leave it parked in such a way that the sun is only on the left side, go to check and find the right sides are still around 35 while the lefts have jumped up to 38-40. Tires that were inflated well in the afternoon during an Indian Summer can drop pressure when the first frost hits triggering the warning light. (Probably not a scenario you'll experience unless you go up to play in the snow)

Thank you.
I still go to dealer for a check since it is near my workplace.
Hopefully that because of the temperature.

LA was too hot this few days.

Good to hear. I'm in LA and got the light this morning too.

Same thing happened to me this morning. My TPMS light came on. I put another 3 lbs of air in each tire. TPMS went off after about 3 minutes. It's most likely temperature related. In So Cal we had also been going through a horrible heatwave (95-100 F temps). Expanded the air in the tires. Today is a full 10 degrees F cooler from yesterday contracting the air in the tires. Our heatwave has finally subsided.

The stock tires are rated at 50lbs psi max. That being said and the car being light, I raised mine to 40 and I like the way they grip better and the way the car drives better. Not much difference in roughness either.
You can tune your front to rear bias by putting less air in the back for a more tail happy car. I do this....makes the rear come around in a corner more like I want....

I put about 24k miles a year on mine and do check tire pressure regularly until about last year when I find it moot as it's always good.

Then last week, the light came on after a refueling stop in the morning. I ignored it as usual as it's always been a non-issue with other cars other than 1-2 psi lower. Not in the case as by lunchtime, I had a almost flat tire. There was sufficient air to drive across the street to America's Tire. I must have picked up the screw in the morning.

as needed?

The light turns on for me during the winter in the morning, but turns off once it gets warmer. Could that be the same for you?

Mine is turning on in the morning at low to mid 50s. It turns off when I leave work when its 70s.
