Frequently asked questions

Where do I find my tyre size?

On the side of your tyre, in your owner's manual, on a sticker in the door frame or fuel flap, and on your certificate of conformity (COC).

What if my certificate lists two sizes?

Then both sizes are approved for your car. You can choose, as long as tyres on the same axle are the same size.
