Dunlop E4 tire "delaminated"

Post by AZgl1800 » Thu May 03, 2018 12:08 am



I caught this picture today on Facebook.

The E4 tire on this 1800 delaminated, and it was only two months from installation by a Honda dealer.
I'm not sure it did, but I was not on scene to inspect it closer.

He is a bit perturbed about this, but as one reader posted, they have never heard of an E4 tire going bad yet.
Dunlop says it is proof that the tire was run at low pressures, Ashley Severe says 'not so'.















The dealer gave him a new tire... but Dunlop won't...

see his FB post for the full story.

I have to side with Dunlop on this one. This is not layer delamination, it does not even look like vulcanization failure. I have seen this kind of damage/failure twice before - once was impact damage from a very large pothole, where the tire was hit so hard that the wheel rim pushed into it and sliced it. The other was damage from running at very low pressure, where the sidewall was repeatedly flexed until it failed on the inside exactly like is shown in these pictures and video.

That tire looks to be chewed up not delaminated. I see what looks to be internal damage as if the tire went flat popped off of the rim and the rim cut into the inside of the tire.

With regard to the video. Is there a rule that video can be no more than thirty seconds and that constant movement of the camera is encouraged so one cannot actually get a good look at something? Just that I often see these video clips which ramble over the place and to me are absolutely useless.

IMO,
Rider Failure.

Improper inflation pressure.... wanna bet only set it at 30-33 psi to start with and never looked at it again?
No, I don't think he ever looked at the tire pressure ever, the dealership installed the tire, and he went riding.

end of story.

I have read that post and I would also say that it is low tire pressure malfunction. They said that they checked tire pressure the day before and just looked at tires that morning. I dont think they said what their tire pressur was. They said that this happened 2 hrs into the ride. They never said anything about the type of valve stem they had on the rim. I have heard several times the rubber oem valve stem going south. They are also not using any form of tpms. So they can not say for sure that it is a delamination problem.
Point is to check your tires before every ride. I'm checking my tire pressure continually, I have tpms and love it.

I installed TPMS a year ago, but have been leaving the FOB in the trunk.

Think I will move it to the 'cab' and velcro it in place so it can actually be looked at once in a while. :lol:

Definitely got me thinking of TPMS. I check mine weekly, and rarely have to air up, maybe once every couple months if the temp swings wide.

I think it's interesting to see the pressure change and tire temp.

you got the ID of the pix, what you need to do is a Right Click on CycleMax's picture, then click on "copy image location" then you paste that into the "Landscape" icon link at the top of the editor.

Thanks John, I'm doing all this from my phone, it usually works.

When taking Cellphone pictures, Always hold the phone 'Horizontal', if you don't, the attachments come out rotated 90° as the one in your photo here did.
