I’ve got a 2020 X5 with the 22 inch continentals. I’ve had the car since mid November and have always had a humm from the tires. Had them checked and even got the fronts replaced for a defective tire and one rear replaced for a nail. Depending on the road surface the tires make a lot of noise. The other day they were super loud on a stretch of road. I’ve had low profile tires before but these are the loudest.
If you have the run flat continentals they are very noisy. Best way to reduce the noise is to get a non run flat tire. But if you don’t have the optional spare this could leave you stranded. Some people don’t care about that.
