I have a 2014 Sonata with 59,000 miles on it. About 6-7 months ago I started noticing a humming/roar in the rear of the car at lower speeds around 20-30 mph. I didnt think much of it at first and over time I guess I became use to it, however it is getting worse and louder.
I did some research and thought I had it narrowed down to the rear wheel bearings, so I scheduled an appointment at my local dealership for repair. After going over the car, I was told that the wheel bearings are fine and no issue there and the noise was due to the tires. They said I need an alignment and new tires.
The tires on it are original with now 59,000 miles and the tread looks good and no obvious issues, but I am no tire expert.
Question is, could the tires be the actual issue and not something else??
Once again, it is a humming/roar and it’s noticed at all speeds really, but really loudest at around 20-30 mph.
Just want some opinions before I drop $400 on new tires if that wont solve the issue.
