Finding the correct tyre size for your vehicle is crucial for safety, performance, and legal compliance. The tyre size information can be found in several locations on your vehicle and documentation.
Where to find your tyre size:
- On the sidewall of your current tyres - look for a code like "225/45 R17 94W"
- In your vehicle's owner's manual
- On a sticker inside the driver's door frame
- Sometimes inside the fuel filler cap
- In the glove compartment
Understanding the tyre size code: Using the example "225/45 R17 94W":
- 225 - Tyre width in millimetres
- 45 - Aspect ratio (sidewall height as percentage of width)
- R - Radial construction (standard for modern tyres)
- 17 - Wheel diameter in inches
- 94 - Load rating (maximum weight capacity)
- W - Speed rating (maximum safe speed)
It's essential to match these specifications exactly when purchasing replacement tyres. Using incorrect sizes can affect your vehicle's handling, fuel economy, speedometer accuracy, and may invalidate your insurance or fail an MOT test.
