Correct answer
They may impair safety and increase wear and fuel consumption.
Safety and handling may suffer, with increased tyre deformation, heating, wear and rolling resistance. This does not mean every braking event is necessarily ineffective and unstable, but do not maintain pressure below the specified value. Check and adjust cold according to manufacturer instructions and load; do not bleed a hot tyre to match the cold value.
