vibration hum tires?

i know my tires are loud but it seems like they are getting louder and i have maybe 2k miles on them since i put them on. the other day i chaeked the air and they had 30psi in them so i thought ill put them at 34psi cause i ran my old bf's hight and it rode better.

here are the tires
http://www.tirerack.com/tires/tires....nture+AT+KL-78

so i did and i cant tell but it seems like its a lot louder then before and with the windows closed i can hear the humming loud and some vibration in the floorboards but it sounds like the tires. ill have to put them back to 30 and see what happens but is there anything else that can happen to the truck drivetrain to make it start humming and vibration if something is going bad on it

o ya is it seems to go away if i turn left or right then it comes back again lol

i was thinking could it be out of alignment? i just realised that the nois goes away only if you turn to the left? cause the tires are like brand new and i'm about to rotate them.

any pulling on the truck? or odd wear on the tires?

you said vibration, they could be out of balance also...

A tire will get louder as it wears, and if you get some odd wear it will get real loud, mainly when you are braking or just creeping along. I would rotate them and see how loud the back tires are on the front and see if they get louder real fast. If they do then your alignment is probably a little off because they shouldn't get dramatically loud over a short period of time.

when you turn left you un-load the left front wheel bearing. i would start there.

if the bearing is bad it will make noise while driving stright but when un-loaded (ie turning) the noise will go away.
