Tire wear and surface wear due to studded tires, yes. Most run studless but they're soft, and we often have long periods of mostly dry roads so they wear, especially at the start and end of season when temperatures are relatively high. And a fair few still use studded even though they have to pay a fee, as they have mountain cabins they use during the winter, and the studs wears the road surface. It's coupled with Oslo being mostly surrounded by hills, so we often get inversion layers trapping the cold air, so the particulates aren't blown away by the wind.
