Find Tyres for Daihatsu Sirion

Frequently asked questions

Quick answers about UK tyre fitment, MOT rules and seasonal options.

• What pressure should the Daihatsu Sirion run?

  The correct pressure for your Daihatsu Sirion is on the placard inside the driver's door frame and in the handbook — not on the tyre itself. Pressure varies by load and trim. Check cold once a month.

• Where do I find the load index for Daihatsu Sirion tyres?

  Load index appears at the end of the tyre size, just before the speed rating — e.g. 91V means load index 91, speed V. Match or exceed the original load index shown on the door placard of your Daihatsu Sirion.

• How do I find the right tyres for a Daihatsu Sirion?

  Start with the size printed on your existing tyre sidewall — for example 205/55 R16 91V — and use it as your baseline for the Daihatsu Sirion. Match width, profile, rim size, load index and speed rating before considering brand or pattern.

• Where can I find the tyre size for a Daihatsu Sirion?

  On a Daihatsu Sirion, the original tyre size is shown in three places: the existing tyre sidewall, the placard on the driver's door frame, and the vehicle handbook. The door placard is the manufacturer-specified original equipment.

• What's the legal tread depth for a Daihatsu Sirion in the UK?

  The UK legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Many tyre safety bodies recommend replacing at 3mm for better wet weather safety on the Daihatsu Sirion.
