Theres a road noise like a humming that increases with speed and becomes noticeable above 40mph. The noise does change when I turn the wheel when I turn towards the left it kinda has a grinding feel to it, if i turn to the right it feels smooth
It seems to be inflated, havent tried rotating the tires, could it be out of balance or alignment is way off, theres been alot of snow maybe something is stuck in there?
Braking seems to be normal so I wouldnt think its a warped rotor or anything like that
I'm kinda clueless on this problem as I've never experienced anything like it before, any ideas here?

Sounds like you need a new hub.
Grinding/Vibrating feeling and humming noise are Wheel Bearings for sure.
About $50 dollars at Advanced autozone, it comes as a whole hub assembly
1 Take wheel, caliper and rotor off(caliper comes of by loosening 2 bolts in back)
2 Remove axle from hub....Almost positive it's a 29mm DEEP socket, you need ALOT of leverage, my air gun had throuble with it. Once its loose, if you do not have a hub puller, get a heavy hammer and put the axle nut slightly on the end and bang the hell out of the nut until the axle moves back (Only hit the nut so you dont ruin the axle threads and a new nut comes with hub assembly so dont worry about ruining the nut)
3 There are 3 holes in the hub assembly, find one that lines up with the 4 bolts in the back, they are torx bolts which look like stars (T-55 i belive is the size)
4 Hub should come off now, but it most likely is stuck on by rust....chisel and hammer it until it falls
5 Repeat the steps backwards to put it back on, it comes with a plastic circle seal thing, to be honest, i could not find a purpose for it, i tried all different spots and it only got in the way, haven't had any problems without it and old one didnt come off with it
took me maybe 3 hours, Axle nut was the hardest part, it's pretty simple to do, just some struggling with breaking the bolts loose
Good Luck!
Btw i drove with mine screaming for about a 1000 miles so it's not really a "don't drive it until it's fixed" type of thing, just get it done soon as you can.

Axle nut is 30mm deep socket! not 29mm, just poppin back in to let u know
Yes it sure sounds like a wheel bearing to me as well.
