>My car also creates a lot of white noise.

Different tyres will change the noise of a car too.

When I bought my last car, it came with a mishmash of different brands of cheap crappy tyres. They were quite noisy all the time, but when you hit exactly 80km/h there was some kind of resonating drone as well, that was very weird...

When I replaced them with good, high-end softer tyres, the noise was reduced by a massive amount all the time, and no more drone.
