215 is the tyre width in millimetres, 55 is the sidewall height as a percentage of the width, and R17 means it fits a 17 inch wheel. You can confirm it on the tyre sidewall, where it appears as a full size string. Always cross-check with the driver door sticker or handbook, as some trims allow more than one approved size.
Choose a load index and speed rating that meets or exceeds what your vehicle manufacturer specifies on the door placard or in the handbook. Common examples in 215/55 R17 include 94V for standard fitments and 98W or 98V in XL versions, but your car may differ by engine, trim or axle load. If you are unsure, match the markings on your current tyres and then select a like-for-like replacement.
If your vehicle placard or current tyres show XL or Extra Load, you should stick with an XL 215/55 R17 to maintain the intended load capacity. XL tyres can suit heavier estate variants, frequent passengers, or regular motorway luggage loads, but they can feel slightly firmer than standard versions. If XL is not specified, a standard construction is usually the best choice for ride comfort and compliance.
Yes, 215/55 R17 is used on several trims of those models, especially where 17 inch wheels are factory fitted. However, the same car line can also come with different wheel sizes and tyre profiles, so the only reliable check is the tyre sidewall and the door placard. Confirming those markings helps you avoid ordering a size that looks similar but will not match your wheel or manufacturer approval.
Replacing tyres in pairs on the same axle is recommended, so handling and braking stay consistent left to right. If the other axle has very low tread, uneven wear, or older tyres, replacing all four 215/55 R17 tyres can deliver more predictable balance and reduce the risk of mismatch. For vehicles with all-wheel drive, check the handbook, as some systems require closely matched tread depths across all four tyres.
