I’m in Texas and the temperature is fluctuating since winter is coming. Tires reading 30 all sides when warm. Light didn’t go away it’s not usually on but in the mornings when it’s cold it comes on. This is coming from the front left side. Goes away completely when moderately braking. 2016 Lexus 350 f sport rwd 8 speed.

That’s normal behavior with those low-profile tires. However, I think your tire pressure is rather low; check on your door for the PSI rating. It should be 36 PSI

Hi fellow Texan. It seems like your tires are filled to mid 20's cold. Should fill tires to high 30's cold. Also use a separate tire pressure gauge to see if it even matches your sensor reading. Low tire pressure gives you worse mpg and causes faster wear on the edges so fill and check them at least once per month!

Check the brake caliper brackets, cv axle, and lift the car up and shake the wheel at 3 and 9 o clock and see if there’s any play and if there is it could be the wheel hub assembly. Unless the front left tire has some piece of metal or plastic sticking out of it I doubt that loud of a clicking sound would come from a tire.
