NOTES:

- This chart is based on the load per tyre. Please check the tyre dimensions before replacing tyres with different sizes.

- This chart does not imply complete interchangeability. Tyre interchangeability is not always possible due to "differences in rim sizes, tyre dimensions, load ratings, wheel-well clearances, vehicle handilng and manufacturer's recommendations".

- Always check the vehicle manufacturer's recommendations for tyre size options before replacing tyres with different sizes and/or rim sizes.
