Hi, around 4 years ago complained to Motability that the car was unsafe to drive and would loose grip and slide. It was winter and all 4 tyres were just above the 1.6 mm and quickfit were refuseing to fit new tyres.
Then added my autistic son would go into a fit and start screaming every time the car slid. Thus meaning he would no longer go out in the car.
Mobility othorised a complete new set of tyres and after more talking Michelin Cross Climates were fitted.
I took from this that at that time if you had a medical issue then Motability would pay for none standard tyres.
