3. As approved by a licensed garage.
4. Correct answer: As determined by the manufacturer and noted in the vehicle’s registration document.

WhyYou may fit only tires of the size set by the vehicle manufacturer and noted in the registration document. A different size is allowed only by the Licensing Authority. The opinion of the tire maker or a garage is not enough.
