Low to mid pitch humming increases with wheel speed, not engine speed. Got new Pilot Sport PS2's abou 3k mi ago, but didn't notice this until about the last few days--getting worse. Does not sound electrical like a pump. Can't tell if worse with loading/unloading as mentioned in searches. I thought I'd reached zen, but any help would be appreciated--car has 60k miles on the clock now.

what speeds does it show up at? does it get louder and then softer the faster you go?

Both my rear wheel bearings went at about 65k miles. Starting at about 45mph, the noise would show up. Get really loud at 65mph. And then soften a bit above 80mph, but not go away.

Can't tell f/r but is most noticable int the 40-65 range maybe because wind/road noise above that

If the heavy left/right turn doesn't change the sound, then probably the rears.

Thanks, any other thoughts? Very well may be the problem FWI've read.

Last time I thought it was WB, it was the tires. They were Yokohamas.

check to see if it gets louder whem you make a turn I just had my 2 rear 1's replaced w/75k on car

It sounds like a metal on metal grinding. It might not be so audible if it's only slightly bad, but worth the little effort
