If the noise is more “growly”, then the issue is likely a bad wheel bearing. The noise may become louder the faster you drive. Yet, if the noise rises with speed, it may also be a sign of chopped tread.

Again, the noise is more noticeable on acceleration because the engine spins faster. The pistons can also wear and make noise.
