Use the registration search for the most accurate match, or check the tyre sidewall for the size format (width/profile/Rim), then confirm against the door placard or handbook to ensure it is approved for your IS 250.

Some cars are set up with the same size all round, while others can be fitted with staggered sizes depending on wheels and trim. Always match what is listed for your exact vehicle and keep load and speed ratings correct, as incorrect sizing can affect handling and MOT results.

Not all IS 250 models require run-flats. If your car was supplied with run-flats and no spare, switching to standard tyres may be possible but you should plan puncture cover (space saver, repair kit or breakdown cover) and ensure the new tyres meet the required specification.

Choose the load index and speed rating shown on your current tyres or the vehicle placard, and do not fit a lower rating than specified. If you are comparing options, prioritise the correct rating first, then decide based on comfort, noise, wet grip and mileage.

After selecting tyres that fit your Lexus IS 250, you choose a nearby fitting centre, select an appointment slot, and pay online. The tyres are then sent to the garage ready for your visit, so fitting is handled locally at the time you booked.
