Tyre size can vary by year, trim level and wheel diameter (commonly 16 to 18 inch options). Use the registration search for an exact match, or check the tyre sidewall for the size format (for example 225/45 R17).
It is best to stick to the approved size, load index and speed rating for your Lexus IS 220d. If you change size or rating, it can affect handling, braking and insurance. If your car uses a staggered setup, keep the correct sizes front and rear and always match tyres across the same axle.
After choosing tyres, you select a fitting partner near you and choose an appointment slot. Your tyres are delivered to that garage, and you turn up for fitting at the booked time.
All-season tyres can be a strong option if you want dependable wet-weather performance and better cold-weather traction without swapping tyres each winter. If you drive frequently in very cold conditions or on untreated roads, dedicated winter tyres may offer extra grip.
The legal minimum is 1.6mm across the central three-quarters of the tread around the entire tyre. Many drivers replace at around 3mm for better wet braking performance, and tyres below the legal limit can fail an MOT and risk a penalty.
