Red sky at night

Back home after the last childminding, seems very quiet here. Had my car MOT and service today which cost over £600. On the way back from the garage with G following me he began madly flashing his lights and honking the horn. Pulled into a carpark and smoke was issuing from a rear wheel.I leapt out and the wheel was incredibly hot. G drove the car back slowly to the garage and we left it there to be investigated. They returned it later saying they couldn't find any reason for the problem and nothing untoward showing up. Fingers crossed it will be ok tomorrow.
Hope the red sky is a good omen.
