I can hear my tire, what could it mean?

New here and new to forums. I need to take my tundra to a mechanic, but I need help telling him what I think the problem is.
I noticed my 2016 Tundra started to feel like it wasn't driving as smoothly as it used to. I can also hear a noise coming from a tire on the passenger side. Like I can hear the tire (hard to describe) Any ideas?

 

It could be out of balance or it could be a screw, nail, or rock stuck in the tread.

 

I've looked at all the tires and see nothing. It doesn't sound like a clicking sound. It's more of a hum, hard to explain. I can hear it rotating.

 

Welcome from NY.

Could it be the rear brake caliper sticking?

Can you post a picture of the tire showing the tread and a picture looking thru the rim showing the rotor and brake caliper?

 

Tire noise can come from a variety of causes. Common causes for sudden noise would be low tire pressure, a separated belt within the tire casing, or objects or debris stuck in the tire tread. Other causes of rotation noise from a tire that develops over time are usually tread loss related from normal, or unusual wear patterns from poor alignment. A failed suspension part could produce alignment wear overtime. Non-tire related causes include the front wheel bearing, front differential bearing (unusual for passenger side on Tundras) and brake components that contact while driving from warped rotors or sticking calipers.

 

Hows your alignment? You may have a bad alignment causing the tire to cup. Post some pictures of both front tires for us to further help you. In all honesty, its very hard to diagnose a noise without pics, videos, description of the tires etc etc etc

 

Thank you for the suggestions. I knew I was reaching when I asked ya'll to diagnose the issue. I do appreciate the feedback that I have received and will get it
into a mechanic. I drive a lot of miles daily and pick up in small changes.
