Tire Splitting/Separating

Recommended Posts

Has anyone experienced a tire separation issue like this?  I have 1148 miles on the tire but all have been in the last eight months.  I run 17 psi in the tires.

I ordered one on Wednesday but I really don't think the tire should be falling apart like this.  I wanted to document it for Sondors to provide feedback to their tire company Chaoyang.

I agree the tire shouldn't separate, but ... look at it... you have almost worn it completely down. 

At this point this is a worn out tire that should be discarded about now anyway.

I’d say that it looks like the tire split because of Rot. I’ve seen this on fairly new unmounted car tires that collected water when left outside. The Question Is, what caused the rot. Most offen it moisture. For instance, if that tire was ridden in spoke deep salt water and it entered the wheel, I can see where the cord could rot like it appears in those pictures. Was the spool of cord exposed to water or chemicals and saturated,  before the tires were manufactured? Certainly a possibility in an economy drive by very low prices like China and I could understand the condition of the cord in a tire with that kind of wear.  I would have to say that with as few negative reports on the Chaoyangs,  that this is an very isolated anomalie. Nonetheless the proper venue to report the issue is to Sondors.com, not the Owners Forum. 

I have 5 sets of 26” Chaoyangs that came on new bikes and I’ve got to say the are really pretty robust tires.

Since that cut is centered right on the contact patch, I’d guess that your flat was caused by some sharp object you ran over, not along the seam that would cause cord failure or separation of the cord belt.

I double checked bike path and even reviewed the ride video several times, and there was absolutely nothing could of cause this rupture.  First and only time had ever happened to me, and it was loud.  I did run it at 85 PSI for better high speed stability, but it is rated 100 PSI.

Reddy, my bike is kept inside the garage, never outside, and I take very good care of all my 'toys'.  When I removed the tire all was dry inside, no water at all.  The reason I'm certain it's a defective tire, is because the rubber was much more thin at the splitting location. 

The attached photo is of my front tire, with the same mileage as the defective rear tire.  It does have some wear but as you can see, nothing like the rear tire.  The first video attachment is a short clip of the tire before I replaced it, showing the tire warp that could have caused the irregular wear and splitting.  The second clip shows the entire circumference of tread to show the tread clearly wearing more near the splitting location, more evidence of a defect. 

This info is being offered as feedback to the forum with the hope that it gets back to Sondors to discuss product quality with their suppliers.

Thanks JCJ,

I’m sure everybody here can appreciates your quandary but since yours is the only post, to ever complain about the quality of a worn out tire on this forum, as I have reiterated above, your displeasure and concerns need to be directed, as you wish, to Sondors.com.

As far as tire wear is concerned, rear tires wear at more than twice the rate of front tires, because they are on the drive wheel and have the burden of supporting more weight, so I’m not sure why you even bring the front into the comparison. I can attest to that fact as my Original Fat now has 8900.3 miles and I’ve been thru several sets of tires, now on my 3rd Rear 26x4.7” Vee Tire Co. Mission Command,  to my single 26x4.0” Front.  My two Sondors Narrows are not ridden near as often but those original Chaoyangs are in great shape. 

This forum is run and supported by owners and we have no formal association with the Sondors Company nor does Storm monitor this site. Again, Please take your complaint and concerns to Sondors.com, follow the Request for Support, and to Chaoyang.

Thanks again

Sondors is now managing its warranty and tech support through the Facebook group, as you can see from their web site.  As part of that, the separating tires are a known issue and there have been enough reports and photos showing the same problem to conclude there was a bad batch of tires.  It is being dealt with individually. 

In the case of JCJ's situation, there isn't anything to warranty as he already got the full use of the tire... it is completely worn out as pictured (sure you could push it a little further, but no one would argue the move's safety with a straight face even if, as an owner, I might do the same thing myself... I'm just a cheapskate who carries tire patches along with me).   Using the model of auto tires, a tire manufacturer or shop gives a percentage credit for the unused portion of your defective tire, which in this case is essentially zero.

@JCJ keep an eye out for the front tire.  It could go, or be just fine forever.  If you do have a failure on a tire that has wear left on it, visit the Facebook group and post pics just like you did here.  If its an issue that rises to a warranty service level the admin staff will tag in a member of the Sondors team who will help you personally.

One more thing, direct to @JCJ:  You stated 1148 miles on the tire.  Yours is the first of these failures I have seen that took so long to evidence itself.  In every prior instance, it was a tire that hasn't been used much.  This example is a typical one. 

This tire had 700 reported miles at 16 psi on it.  You have less than twice that and your tire is worn completely down.  Since the rubber compound on these tires is known to be pretty durable, there's something going on with your use.  Its not tire pressure as 17 psi is not an issue.

And another.... Also barely worn.

I just picked the last two reports.  These are typical examples.  Note both tires have almost no wear.  Again if you see this issue follow the instructions on the Sondors site and report the problem with pictures.
