Why this is the answer
The correct answer in the official bank: As determined by the manufacturer and noted in the vehicle’s registration document.
Tire size affects road grip, braking, stability and the accuracy of the speedometer. So the permitted size is the one set by the vehicle manufacturer and noted in the vehicle's registration document. Any size you want, the size set by the tire manufacturer, or the size approved by a garage is not the permitted size.
