Find Tyres for Lexus IS

Frequently asked questions

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

• Can I mix tyre brands on a Lexus IS?

  It's safer to fit matching tyres in pairs (axle-by-axle) on a Lexus IS. Mixing brands or different tread patterns across an axle can affect handling balance — particularly in wet conditions.

• Where do I find the load index for Lexus IS 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 Lexus IS.

• Are all-season tyres a good choice on a Lexus IS?

  For UK drivers, all-season tyres with the 3PMSF symbol can be a sensible compromise on the Lexus IS — particularly if you do mixed mileage and don't want to swap between summer and winter sets twice a year.

• Why does the Lexus IS have different tyre sizes by year?

  The Lexus IS 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 can I find the tyre size for a Lexus IS?

  On a Lexus IS, 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.
