Recently replaced all tires and vsc seems to sometimes activate and make beeping noises when going around sharper bends, even on only wet or dry pavement, not even snow.

    tires are all the same size but i checked couple of days ago and both front tires were a bit overinflated. Both front tires were about 38-39 psi and both rear tires were about 34 psi.

    Check tire pressures including spare (Lexus monitor tire pressures of all spares if they are full size). If pressures are OK you will need a scan tool to retrieve codes stored, codes may not be retrieved with many generic code reader.

    both front tires were overinflated, about 38-39 psi, and both rear tires were about 34 psi. There was no type of sensor attached to the spare tire. The warning light on instrument panel and the beeping noises have not come back in the past week or so, and i just corrected tire pressure about 2 days ago, all tires now about 34 psi.
