Tires Hum when cornering
I did a search yesterday for tire noise on curves,,, only found post about Bearing failure... When on the jack lift, the rear tire spins easy with no grind or clicking... Years ago, I had a Sporty that had bearing failure, and this is not it.
My '13 Ultra(bought new 8/5/13) started making a humming noise when cornering at 40 mph+ after I hit about 6500 miles on the bike, riding 2 up going straight it does not do it,,, lean a little to the right and it hums a little,,, lean it to the left and it's the loudest... it still has the stock Dunlops on it... Doesn't seem to do it right away,,, but after riding it for say 20+ miles.. I run 36 lbs in the front & 40 lbs in the rear... and I check them weekly.
Any ideas?

Yep, I'd say it's normal. I have a 2010 CVO SG, and with the 18" rear wheel, I'm limited on tire choices to the stock Dunlops from HD.
They're pricey at over $220 for a rear, but I'm well into 14K miles out of my back tire. These tires see plenty of twisties, but the centers where down fastest. Now, when cornering, I get the howling, just due to the wear patterns.
Nothing to be concerned of....You'll see as soon as you get a new pair of tires, it will go away.

. Thanks for the replies..
Okay, I understand the tire cupping on the Dunlops... On my '05 RK the original Dunlop front tire had 22k on it and you could feel and even see the cupping on it...
Never had the howl before...
Don't know if I agree that improper air pressure is the cause of my problem, as I said I check my tire & rear shock pressures weekly...
