DUNLOP E4 TIRES HUMMING

Post by gford »



I installed a new E4 on my buddy's 2000 se and when driving behind him i can hear the tire humming. I checked the tire and there are no marks or and signs of rubbing. The sound changes when driving over different surfaces from a loud drone to nothing. I just replaced my 99se rear with a new E4 and mine is doing the same. Bike handles good and no signs of anything rubbing. Just concerned about the humming. I have changed many tires and double checked everything and everything looks good except for the humming. Anyone else experience this and is this just the thread pattern on rough surfaces creating this sound.
The sound can't be heard on the bike, you have to be following behind to hear it but it is very prominent

what tire pressure ?

I like to run 44 psi, best tread life, and helps prevent cupping.
balance beads also aid in preventing cupping.

first I have heard of the humming sound though.

My buddy and I are both running E4's and we have noticed different tire noises on different surfaces. Concrete seems especially loud.

Yes, me too. I have them on both the 1800 and 1500. The noise is noticeable. I've got about 10,000 miles on each set.

Tire noise at 40 PSI is no different than the E3's I took off. They were 8-10 years old, though! :O

I've had my E4's on for about 1k miles now and haven't noticed any humming myself. For now I'm still running the recommended 36F/41R pressures.

Ok but what is the tire grip wet and dry, handling characteristics along with longevity?

I have tire noise on my car and trucks, if you live by a highway what do you think is all that noise heard beside the truck stacks and Jakes????
Used to climate controlled cages? All tires make noise. :?:

Sounds like normal tire on pavement noise to me. I have around 9k (almost no visible wear or cupping) on my e4s. I removed e3s early because of the noise and vibration due to cupping. The e4s are a marked improvement over the e3s.

Mine make noise too, but they handle great for about 10000 km by now. In dry and wet.........

Still happy with the handling of my E4's, but they are definitely starting to hum now, both front & rear. No vibration (used Dynabeads this time), great traction, but they do sing in the turns....

My bike had E3s on it when I got it.
They didn't hum, they HOWLED in the turns!
No more Dunlops for me.
I run a Michelin Commander II on the front
and a car tire on the rear.
Couldn't be happier.

I've had tires do just what you mention. Different pavements, different hummmms.
What I found is the treads that have dead ends (see pix) tend to 'POP'. It's the air being trapped (pressure) then releasing (vacuum).

I took a mid-size beater straight blade screwdriver & ground it to cut/scratch on the pull stroke. Don't need to go deep if just testing.
I then scratched in the lines on the SpitFire tire (see pix). The high pitched popping stopped until that scratch area wore down then the popping returned.
A Dremel works also but grabs as the rubber heats up.

When I do one thing, I'll sidestep a little & learn many things.
