When changing wheels
The car's wheels can be changed, e.g. to winter wheels or a spare wheel.
Follow the relevant instructions for removing and fitting wheels.
When changing to another tyre dimension
Check that the tyre dimension is approved for use on the car.
Contact an authorised Volvo workshop for updating the software at each change of tyre dimension. A software download may be necessary both when changing to larger and smaller dimensions, and also when switching between summer and winter wheels.
