Hum while driving
I have noticed a very low buzz/hum while driving almost like what monster tires make. It is a 2018 F150 Powerstroke with 97000 miles, I noticed this late last summer and thought it was the original Michelin tires as they had 93000 miles on them, I have done all new Ford pads and new tires but this very light hum is still there I don't think its a wheel bearing as it doesn't go away during cornering (had a car once before that would do it only while cornering)
I don't feel like going to the dealer so they can charge $140 an hour only to say nothing is wrong. Anyone with any ideas or has anyone else experience something like this?

I know exactly what it is. Easy fix/adjustment.
Remove the plastic valve cover. Take a look at the drivers side firewall. You will find a bonding wire that is laying up against the firewall and also the plastic valve cover in the same area.
With the plastic valve cover off drive truck after you have bent the bonding wire for clearance to isolate the hum. Reinstall plastic valve cover and check for clearance with bonding wire.
A zip tie may help keep things in place. Sound great with the hum gone.

Welcome Henrylarry, check out the forums that are dedicated to your vehicles if you have time.
100,000 miles on the odometer most likely its the right wheel bearing. ?? Of course tires make noise also ?
As for the noise, especially If it changes at long corners and 50 + mph, pull the tire, remove the brake caliper and see if you feel the rough wheel bearing, they are weird.
The brake caliper with pads supports the weight of the Rotor and Bearing spindle, thus it's hard to detect the problem until the Caliper is off the Rotor. Then it's
easy to feel the rumbling sucker. The reason for the change of noise is the damage to the bearings inner stuff.
-----
Salt and where it is hardest on the right front wheel bearing the most and also the worst road surfaces. → → right side of the highway most, accumulation of awful stuff for the rig.
