Check the size printed on the tyre sidewall, then confirm it against your vehicle handbook or the sticker in the door shut or fuel flap. Make sure the size matches exactly, and also match the required load index and speed rating shown on the vehicle placard. If your current tyres have a different size fitted, stick with the manufacturer specification unless a verified alternative is approved.
165 is the tread width in millimetres, 60 is the aspect ratio (the sidewall height as a percentage of the width), and R means radial construction. 13 is the wheel diameter in inches, so it only fits a 13-inch rim. With the 60 profile, the sidewall is relatively short for a 13-inch setup, which can give a more direct steering feel compared with taller profiles.
Use the load index and speed rating specified for your exact car, not a guess based on tyre size. You can find the required rating on the vehicle placard, in the handbook, or on your current tyre sidewall if it matches the original fitment. When buying, choose a tyre that meets the required rating, and only go higher if it is compatible with your vehicle specification.
It is best to keep the same size on both tyres across each axle, and ideally the same size on all four wheels. Mixing sizes changes the rolling circumference and can affect grip balance and the way ABS and stability systems behave. If you have a temporary spare that differs, drive cautiously and replace it with the correct size as soon as possible.
For stop-start urban use, prioritise strong wet grip and good wear resistance, as these tyres see frequent braking and tight manoeuvres. If you drive all year, an all-season option in 165/60 R13 can suit mixed UK conditions without switching sets, while a summer tyre can feel sharper in warm weather. Compare EU label ratings for wet grip and noise, then select a brand and pattern that matches your budget and driving style.
