When looking at the tyres currently fitted to your truck, you will see the tyre size represented by a series of numbers and letters.
- In the above example, the tyre size is broken down as follows:
- 385 | The tyre width in millimetres
- 65 | The tyre’s sidewall height as a percentage of the width. In this example, 65% of 385mm – this is sometimes called the aspect ratio.
- R | The R tells us that is of Radial Construction
- 22.5 | The diameter of the tyre's inner rim – this time in inches
