Specific patterns and stock change. Match the placard's size, load index and speed rating, and confirm suitability for the vehicle's weight and drivetrain.

Replacement checks

Confirm grade, powertrain, build date and tyre placard.
Match load and speed ratings, not only tyre size.
Check TPMS, wheel condition and spare/repair kit.
For AWD vehicles, keep all four tyres closely matched.
Arrange wheel alignment for uneven wear or steering pull.
