Hi all, new guy here.
First off, I just want to say that I came across this forum shortly after purchasing a new old stock 2008 Xciting 500Ri last fall. It's been great to lurk around and read all of your opinions and advice about the bike, which I absolutely love. It's become my main ride this spring and summer; I take it everywhere I go, rain or shine. There are almost 3000 kilometers on the odometer at this point.
I just became aware of a disconcerting issue over the weekend. A friend and I were looking at my bike; he was checking out the front brake disks when he noticed a crack in the front tire that goes all the way around the rim. It's right snug up against the rim, and almost invisible from a foot away. However, it is definitely a crack all the way around the tire, easily seen in the pictures below.
I have no idea how long it's been there. I always maintain the tire pressure around 33 psi (it's the original Maxxis tire), so I'm stumped as to its origin. My thinking is that either the tire has a manufacturing defect, or was installed incorrectly, or just plain dried up while sitting in storage for two years before I bought it.
I took the bike to my dealer yesterday for inspection. He says that it's cosmetic, and nothing to worry about, but I can't feel safe driving the bike at superhighway speeds with a tire in such a state. I've asked the dealer to contact Kymco Canada to see if the tire can be replaced under warranty, and he's yet to get back to me with a response. We'll see what happens.
In any case, I've learned that one needs to inspect one's tires very carefully, something that I will be doing much more diligently in the future.
Has anyone here ever come across a similar tire issue?

Here's the official reply to me from Kymco Canada:
Hi Eugene,
I have spoken with Rui in regards to your tire and explained to him that
there is no safety issue with it at all.
This crack is just in the cosmetic layer of rubber put on the side of the
tire so that they can print the lettering on it. This part has no
structural integrity.
From my understanding the tire is perfectly round ( meaning the belts have
not internally shifted ), does not vibrate, holds air and does not loose
pressure, so it should be perfectly fine to ride on without any concern and
therefore does not warrant replacing.
Thanks for choosing KYMCO!
Best,
Dennis Heilman
Director of Parts & Service
I picked the bike up from my dealer this afternoon, and he noted that the air pressure in both tires was still fine.

I still have the original Maxxis front tire on my '07 Xciting 500. Think I've got over 12,000 miles on it. I'll look at it in the next few days and let you know what, if anything, I see. Maybe they're right and there is no issue.
-
Thanks, Hoolander!
Would you guys feel safe running this tire on the highway at 120 kph? One good pothole and all bets are off.

Just a guess on my part, but I wonder if the tire was ridden flat after it lost air, and what you see is wear from rubbing on the rim. You say you bought it new however, so ???
-
Hi Agent Bob,
Nope, never had a flat and the other side of the tire is in perfect condition. That's why I think it's gotta be a manufacturing defect - either that or the tire was improperly installed.
Thanks for your reply :)

The tire could be old...all tires have a date encoded on the sidewall. If stored on cement this could also happen.
-
I am no forensics traffic expert, but I have seen such things many times and do not consider such a tire to be unsafe.
-
I rode 25 miles to the dealer with the front tire bulging in 3 places. Scooter tires are not made like auto tires. Also, you can examine for yourself, look real close, and you should be able to see if it's just the cosmetic layer as stated. These tires are thick.
-
After much online research, the general concensus seems to be that a visible fault in the sidewall of a motorcycle or scooter indicates a tire which is unsafe to ride on.
I am will take the tire to a Minsitry of Transport inspection station to have it examined.
Thanks for all your replies :)
-
Ok, super 88. I looked at mine and there is nothing like what you have. All I see is a couple places less than an inch where there is some very minor cracking in the same area as yours. Not opened up like yours is.
-
Thanks for checking, Hoolander. My neighbour had a bunch of his harley buds over this afternoon, and to a man, they all agree that the tire appears unsafe to ride on.
I will post the findings of the Ministry of Transport's safety inspection when it has been completed.

Just wondering if you have recived any reply on your tire as to the crack being safe? I looked at three stores and found no crackes in any of 50+ tires that is in the USA.
Good luck with your indever.
-
I had an afterthought about the tire. It was probably factory installed with the aid of a mechanical tire installer and the operator forgot to lubricate the bead, and the machine forced the tire onto the rim and damaged it. Just a theory.
-
Its been two weeks and the MTO has not yet replied with an answer. BTW the director of parts and service for Kymco Canada has flipflopped on the safety issue, and now claims that he is not advising me that the tire is safe to ride on, nor has he signed a safety certificate to that end.
Yet they won't replace the tire, suggesting that I have damaged the tire by riding on it underinflated. I check tire pressure often, and these ones both keep their pressure very well. Even if that were the case, I think it is highly improbable that only one side of the tire would be so severely damaged, while the other side is still in perfect condition.
I think it's a sad reflection of Kymco Canada's commitment to customer satisfaction and safety.
The scary bit is that if I had simply accepted the original assessment by Kymco Canada - that the tire is safe to ride on, and had taken my kid out for a spin, hit a pothole... the consequences could have been catastrophic.
BTW Agent Bob, interesting theory. I had the same thought, and mentioned it to KC but received no reply in that regard.
-
While you purchased the scooter as new - it is a 3 year old bike with 3+ year old tires.
There should be a 4 digit number in the sidewall - something like 4407. The first 2 digits are the week, the other 2 are the year.
In the sidewall you could say that delamination is cosmetic - but that is too close to the bead for comfort if you ask me. Since it only did it on one side the bike probably sat somewhere with either light hitting it or air blowing across it - they both make the rubber degrade faster. How's the rear tire look?
-
Hey JWTR,
I put on my high-powered reading specs and sure enough, the rear tire is showing the same symptoms, again only on one side of the tire, the same side as the front tire. I will post photos once my daughter comes home and snaps them. Not only is there delamination, but the same cracking right at the bead, although it is not as prominent on the rear tire as it is on the front tire.
I know the bike is 3 years old, and hence the tires must be as well. When I purchased the bike, I asked if the dealer would bring in a 2010 model for me, but he made a convincing case for putting me over the curb on the 2008, saying that was is exactly the same bike, with the same full two year warranty, and he would move on the price.
Tires age was not something that even crossed my mind at the time I bought the bike.
I have since read about several cases where dealers were knowingly selling bikes with older tires on them, and not disclosing the pitfalls and dangers of this practice to the customer. In one case concerning Harley Davidsons that were subsequently involved in accidents on these older tires, the dealer was held responsible. The court found that it was incumbent upon the dealer to adequately explain the dangers associated with riding on older tires - something that they failed to do.
Similarly, my dealer never mentioned anything about the aging tires on my "new-with-full-factory-warranty" 2008 Xciting 500Ri.
Whenever an "old stock" new bike is sold - and I'm sure I'm neither the first nor the last customer to purchase an "old stock" new scooter - it would seem to me that the dealer should fully inform the customer of the possibility of premature tire failure - premature in the sense that failure can occur at very low mileage. My tires have 3000 km (1800 miles) on them, and now it appears that they both will need to be replaced.
Kymco Canada continues to insist that since tires are not covered under my warranty, I must absorb the full cost of replacing the front tire, and apparently the rear tire as well.
I love the bike, but in my estimation, Kymco Canada has failed in this instance to provide adequate customer information, service and consequently - satisfaction. Further, I feel that their "concern" for rider safety is woefully lacking, as demonstrated by the quote in the second post of this thread.
The bike has been sitting for three weeks, unridden, as I cannot afford a new front tire at this time, and now that I've seen the rear tire cracks today, it looks as though I will have to cancel my insurance and park the bike until I can scrape up the money to replace both tires.
So it looks like the riding season has already ended for me, unless Kymco Canada steps up to the plate to address the issue. Given my experience with them over the last three weeks, I just don't see this happening.

Rear tire pics...
Cracking along the bead:

Delamination:
(http://i1081.photobucket.com/albums/j342/rrrickyrrrecordo/DSC_0005.jpg)
Not as bad as the front tire, but at 1800 miles? (The rear tire is better protected from light than the front, no doubt about that).
I was surprised to learn that UV light can penetrate glass, such as that in my dealer's front window. Apparently up to 97% 0f UVB is absorbed, allowing only 3% to pass through. However, it's a different story with UVA - only about 37% is filtered out, and the remainder (63% or roughly 2/3) freely penetrates straight through. Apparently, from what I've read, it's the UVA component that is nearest to the infrared spectrum (which can easily penetrate glass as well from what I've read online, and which apparently heats and thus dries rubber prematurely).
I don't have exact dates on hand, but it seems that my scooter sat on display in the dealer's shop for at least one year. That's a lot of UVA and infrared exposure over a prolonged period. I've also learned that tires left sitting stagnant for such an extended period may be prone to premature cracking as well, as tires need "exercise" to help them retain their elasticity. I'm not sure how heating and air conditioning affect the elasticity of rubber, but it's pretty clear that both produce a very dry environment.
In any case, I'm now grounded. Happy trails to everyone here. Safe riding!
:Edited twice to get the UV-A and infrared bits sorted out due to conflicting information on the interwebs!:

I think that you are wasting your time.
1. Nobody will tell you "the tire is safe" for sure, and will not put a stamp on that statement. Of course, everybody will say it is unsafe, just to be on the SAFE side. Personally, I think that tires are OK.
2. I have seen such minute cracks on pretty much all tires, especially OEMs, where the scoots stand in one place for prolonged period of time before purchase (parking lots, salons).
3. If you still feel unsafe, trash them and buy new ones, it is probably less than 100 US$ for sure.
I gave up long time ago on contacting, emailing and requesting anything from companies and shops where I bought my vehicles.
Also, I think that it is possible that there is nothing wrong with them.
-
The tire doesn't have to fail catastrophically to take you down. The lateral forces on the tire near the bead have already caused it to crack right up next to the rim. I would not assume that the rubber actually holding the tire to the rim is in significantly better condition, or that it will not allow the bead to slip - especially on the front tire.
Perhaps you should contact Chen Shin and ask them if the tires are safe (your tires are CST tires right?). If they say to replace them - then that may give you some leverage with the dealer and or Kymco. It would also give you something that you can take to your local news station as a story of interest ("Local scooter dealer sells tires that the manufacturer claims are unsafe").
I'm not above threatening to shame a dealer into doing the right thing. They can take a hit now and have a good public image, or lose sales because they are exposed for selling something as new which is not in a condition which should be considered new, let alone safe.

Thanks for your replies!
Actually JWTR, the tires are Maxxis - I sent them photos weeks ago and have yet to hear back from them.
Axy, you're obviously a road warrior with loads of experience, but I've had many experienced bikers have a look at the front tire up close, and they all say it's unsafe. Of course , you have only seen the photos and haven't seen either tire up close and all the way around.
I cancelled my insurance this morning as times are tight for my kid and me. I can't afford new tires at this time.
I too have given up on contacting KYMCO CANADA - it's a one-way dead end street.
I've not yet given up working toward a solution via other means though. Thanks all for your replies, opinions and advice. You've all been very helpful!
-

My point exactly.
I doubt there is any solace in the fact that no car or motorcycle factory is much better in after market consumer care, except, maybe, premium brands (Mercedes, BMW etc.)
Maybe, just MAYBE they would behave in a better manner.
-
If you think the tire is unsafe, you are wise to continue checking it out.
-
In a perfect world, the dealer would offer to sell you replacement tires at the wholesale price which he would install for free, if he wants to keep you as a valued customer. You can tell him it was your lawyer's suggestion. (Hint, hint.)
-
Now a days there is a comman problems for every vehicle owners to get a some crack form their tires. In today's technology worlld it is to be consider as a fact that newly bikes or each two wheelers have a problems for crack the tires.
-
Wow, old thread/post. Just go's to show you. Never put a Cheng Shin on anything. Cheapest piece of crap on the market. People put them on because they are cheap. But they do not understand they wear out much faster. So you have to pay to have new ones installed more often. Not worth it. :-*
-
I don't need to show you pictures but I have the same year bike bought new last year (never been sold or ridden) and I have similar cracks around the rim. They're not quite as extensive as yours but on a car tire this would suggest age. On a bike tire? New to me. I've only got 6000k on it and bought the 2008 model new from the dealer with something like 54K on it. It's still on the guarantee so the chief mechanic is writing to Kymco to see if it's on the warranty. I'll check back in once I get an answer. Good luck but so far I haven't had any problems and the air doesn't leak. (even after being outside all winter).
-
Years ago on a large bike on the turnpike going 70 the front tire blew, it was new never used before. After 4-5 years sitting in the rafters of a hot gararge not know was that the tire had sarted dry rotting enough to build up pressure and blow. I can give a accident report here from state police and me but it bothers me to even think about it. Whenever there is a tire question all I can say is get rid of it or them and go new. I was very very lucky.
-
I failed to mention and I'm not saying this is so with your tires...please understand. Some of the area on the tire that blew as I remember looked very sinilar to what you are showing. That is not normal for sure or all tires would show that or at least many others of the same brand. Wished I knew what you see and know.
-
Looks like...what we call in the automotive field "dry-rot"
Look for the DOT number. Assuming the DOT is similar to car it will tell the date the tire was made.
No matter what it is UNSAFE. Replace ASAP. :-)
-
You will never feel safe on those tires, neither would I. Simple solution is to replace them, not so simple if you are financially strapped. Better to replace them and then you can examine them off the bike. If they are determined to be safe, you lost a few dollars for piece of mind. If determined to be unsafe, you have a solid case to present.

Thanks everyone. I've been gone from the forum for a while. As far as the cracks are concerned, they're gone.......new tires.
-
Congrats on the new bike. It may be a left over 2008. The rubber is 5 years old. Buy a new tire. Case closed.
Is your safety worth $100 bucks. If it is , sell the bike and buy a car.

Maxxis is does not have DOT numbers for their tires in the US and you can not buy them retail here anymore. They can only be sold in america as OEM from the factory directly imported. Maxxis has DOT reg for offroad tires not on road motorcycle or scooter tires.
