A driver wept in court after admitting causing the death of a pensioner in a road accident.
Andrew Turner, 52, lost control of his car and careered into a Mercedes in which Geraldine Hodge, 86, was a passenger. One of the tyres on his Volkswagen Golf was so low on tread that the canvas could be seen, Stirling Sheriff Court was told.
The condition of Turner's tyres did not cause the crash, which happened near the Falls of Falloch in Perthshire in June last year, but would have affected his ability to avoid the collision, the court was told.
Turner is said to have checked his tyres previously and despite realising they were illegal and unroadworthy, carried on driving.
The cause of the crash was officially due to his "inattention", causing his Golf to skid on the road surface which was wet from summer rain, the Herald in Scotland reported.
The vehicles collided close to the centre of the road, with the Mercedes taking an impact from the side.
Prosecutor Beverly Adam told the court: "The defective front tyre on the wet road would have affected how quickly the Golf reacted to the driver's input as the accused attempted to correct his road position, but had no impact on the eventual outcome".
The Herald reported that Sheriff Wyllie Robertson warned Turner that ''the gravity of this offence brings with it the possibility of a custodial sentence''.
Sentence was adjourned for reports.
