Find Tyres for Aston Martin DB9

Frequently asked questions

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

• What's the difference between summer and winter tyres for a Aston Martin DB9?

  Winter tyres use a different rubber compound that stays flexible below 7°C, plus deeper sipes for snow and slush grip. For UK Aston Martin DB9 drivers in colder regions, dedicated winters or 3PMSF all-seasons can be worthwhile.

• Is wheel alignment important after fitting new DB9 tyres?

  Yes — a wheel alignment check after fitting new tyres on the Aston Martin DB9 preserves tread life and handling. Most UK fitters offer a quick alignment check; major adjustments (camber/caster) require a four-wheel laser machine.

• Where can I find the tyre size for a Aston Martin DB9?

  On a Aston Martin DB9, 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.

• Why does the Aston Martin DB9 have different tyre sizes by year?

  The Aston Martin DB9 has had 3 UK-market generations. Each generation uses a different platform and wheel options, so tyre sizes are not interchangeable across the model's history. Pick the year-correct generation page for accurate fitment data.

• Where do I find the load index for Aston Martin DB9 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 Aston Martin DB9.
