Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tyre.

Common questions
- What size tyres does the smart #3 take?

- Can I fit a cheaper tyre to a smart #3?
