I swapped out new tires for a set of E3's which are everything that all are reporting back about. During the install I also removed the front bumper from my 06 Ultra. I like the look much better with out it. The question comes in now at around 50 MPH I am now hearing what seems like a harmonic hum from the front end. Never had this before, from a logical standpoint as these are the only two changes it has to be one or the other (tire or bumper removal). Can the fender be catching more air and causing this? Guys that are running without the bumper any feedback? Or any other suggestions? I am going to pull the front tire off this morning and reinstall the bumper to see if this changes anything and reinspect bearings, rotors ect.....

 

It's likely the tires. Several peope have said that their E3's are noisy. I've never heard mine though. And I have no front bumper.

 

Mines a Standard so I never had the bumper but, never had a hum either.

 

So guys with the E3's are you hearing any noise that is consistent with what I am describing?

 

Removed front bumper from my Ultra, no difference at all.

Can't expect new tires to respond the same as previous, IMO.

 

E3's are very noisy...that's why I will never use them again..
Avons for me.

 

I have the E3 on my front for about 8000 miles and never heard a hum or any thing else for that matter.

 

I had this happen on my V-rod after a tire swap. It was as simple as the brake piston cocked in the caliper when I pushed it in. the noise was the pad wearing a grove.

 

i'd suggest reinstalling the bumper on the front fender and going for a ride. that rubber bumper might be quelling some harmonics going on. i cannot comment on the e 3's as i've only got the one on the rear for now. when i need the front, i'll replace it with the e-3 also though. replacing the bumper would be the first and easiest way to check if that's the problem. i know, streetglides etc, don't use the bumper.

 

I've had my E3's for about thousand miles. They are no noisier then the stock tires, probably quieter. I know a bunch of people who run them and none has ever mentioned them being noisy or loud.
