How to minimize noise in my BMW M7's cabin?

I recently purchased a BMW M7 and I've noticed that there is a lot of road and engine noise in the cabin. What are some ways I can reduce this noise?

One solution is to invest in soundproofing materials such as acoustic mats or insulation. These can be installed in areas like the doors, floor, and ceiling to absorb noise from outside the car.

Another option is to upgrade the tires to ones with a lower noise rating. This can significantly reduce the amount of road noise that enters the cabin.
