Why does my car drive loudly?
My car is over 135,000 miles and it drive well, but makes a loud hum driving over 45 mph
This noise could be coming from a wheel bearing that is failing or from a tire that is failing. See if you can isolate the noise to a particular location or corner and then inspect the tires for anything uneven on the tread. You might still have a problem with a tire that you cannot see externally. If the tires are fine you might have someone inspect the wheel bearings.
