Leo, I didn't mean rotated like a car's tires. I meant rotated as in turning them around to check all sides.
As for center-standing, I've done it. It's just really REALLY a big production for me. Always seems like Peej is gonna tip, one way or the other. And takes multiple attempts. And sometimes just slides backwards instead of up onto the stand. So I've pretty much given up on the center stand.
I zoomed in on your pic after rocky's post, trying to see how it looks old. Dunno that, but I did see a second small split starting, in the tread pattern above the big one. I'm afraid you would've duplicated your Duke-friend's stunt if you'd driven on it. Do let us know how old the tire is, please! And keep spinnin' those whitewalls!

Kat,
I didn't catch your original meaning of "rotating"... Duh...  Just old age... Yeah, putting scoots on the center stand is a tad "awkward"... It gets easier with practice but I still use the side-stand except when putting the mouse to bed.
That DOES look like another crack beginning. I'd missed it while examining the big one. Not good...I've never had a tire do this in my fifty years of driving... Not even in the "old days" when tires were not all that good. Any old problematic tire showed plenty of signs of dry-rot and checking long BEFORE a split like this appeared. Rocknv may have something there when he mentioned damage from hitting something in the past. I've hit some potholes and road-debris in the past, but nothing recently... especially since adding the new LED lights. I don't think Shinko tires are any more prone to this phenomenon than other brands. This one has performed great until just now. Just one of those things. I did get down and give the REAR tire a thorough inspection in case I had hit something. No problems there. Some riders have great results with the popular Kenda brand. I had them on my 150 and they were fine, and just wouldn't wear out. "Minnie Mouse" had new Kendas when I got her, but they handled absolutely AWFUL on the 250. The Michelin rear and Shinko front tires have been fine performers. I think the smaller the wheel diameter, the more finicky the tires become. Never had this trouble on old Hogs... Just slap a used 16" truck tire on and you're good to go...  Ride safe!Leo

Tires in general are all the same as far as I'm concerned. Story camping next store camper starts a conversation about tires I mention I went to G load range made in china because couldn't find any USA tires. I says to me I would never put on China tires he buy Goodyear. Later that day I was at his camp site happen to look at his Goodyear tires guess were it was made yep china LOL. I called him over and showed him was it said he nearly fell over and said you bet he will be going back to dealer over that. I then googled goodyear tires found they have 6 plants in china. You just never know so that's my point. Our government like fuzzy math like a tire 2 ply this and 2 ply that and 2 ply is rated as 10 ply our government is our worst enemy on safety of tires IMO

Our government like fuzzy math like a tire 2 ply this and 2 ply that and 2 ply is rated as 10 ply our government is our worst enemy on safety of tires IMO Goodyear has a bit better quality control and overall rubber chemistry than the usual Chinese branded tire. I tried the Chinese branded tires on my RV once and though properly inflated two herniated similar to what OldChopper showed us with the belts coming through the treads. They smelled wrong too from day one. When I called for assistance putting on the spare after I noticed one had suddenly increased in diameter the commercial tire tech the moment he got the tire out of the wheel well just froze and shouted "Dear Lord everyone get back!", gently lay the tire down and put a remote deflator hose on it letting the air slowly out from 20 feet away. That guy looked white as a sheet and I can't blame him as those steel belts if they let go on a H rated tire at over 100 PSI would have disemboweled him at the least or possibly even took his head off. |

As usual some don't read or understand what I wrote tires from Goodyear are also made in china and that's china control. Remember our government controls the meaning of what and how it's made so many company's do minimal just to slide by the standards Government sets

The most advanced tire factory in the world is Double Coin's truck tire plant in Shanghai.

Tires in general are all the same as far as I'm concerned. ... Tires might all come from China now, but they are NOT all the same. I got a set of Tigerpaws for a car (thankfully NOT my Taurie-love!). I was working a minimum pay job and paying off my first knee surgery, so had little spare money. I got all four installed for under $100. Good deal, right? Wrong. They had total crap traction. Just doing regular turns at intersections would result in squeal and slight sliding. And no, I am so NOT a turn-demon! I ended up losing that car 'cause I topped a hill and saw a car ahead with its backup lights on, stomped on the brakes and skidded, immediately starting pumping the brakes instead but the crap-tires never attempted to regain traction. Slid off the road, hit the ditch, and flipped the car. I will NEVER NEVER EVER skimp on tires ever again! Now crawford, imagine putting the 2-wheeled equivalent of those Tigerpaws on your scooter. Make your stomach squeam a little, doesn't it. >'Kat |

Remember our government controls the meaning of what and how it's made so many company's do minimal just to slide by the standards Government sets No actually with the Goodyear that are for import into the USA or any other country for that matter they are under Goodyear's more stringent control. The Chinese are only concerned for the most part with whats sold in China The G670 RV for example will last a full 6 years here in Florida because their rubber formulations have more Carbon Black and UV protection than many of the others while the Chinese branded tires depending on which importer ordered them will have substantially less and may quickly take on a brownish tinge. Too many will only hold up on construction sites or short haul trucks where the tires never see high speeds and tend to get torn up beyond use in a year or so. Double Coin makes some really good tires and some really bad ones too. It is all like Chinese Scooters they will only be as good as the US importer specifies them to be. If they are just paying to barely pass DOT standards which are the minimum standards then you will be getting a minimal quality tire. Goodyear has been investing both State Side and abroad to upgrade all factories that make tires for them to meet the Worlds most advanced standards. My family was involved in developing tires for almost 50 years with my Father holding a Masters in Chemical Engineering designing rubber formulations for tires in all civilian, military and industrial applications including some industrial tires that saw high speed use 24/7 until they wore out. My Uncles side of the family mostly designed, built and maintained the Vulcanizers. Family dinners and picnics were more like going to school as everyone talked shop. |

I see Chinese tires on OTR trucks all the time at work...Double Coin, Sailun, Sampson, Union, Gladiator, Triangle, Dynatrac, BOTO, Roadmaster, Aeolus...seen them all. One driver I talked to said that he will never ruin anything but Double Coin for steer tires again. They lasted longer than the Michelins they replaced, for exactly half the cost. He then had them capped, and they had run another 100,000+ miles as drive tires...unlike the Michelins, which had checked badly enough that Bandag wouldn't cap them!

MYSTERY SOLVED... I THINK...
I finally crawled down and examined the Shinko sidewall for its "born-on" date. 06/99.
So..... It's NINETEEN YEARS OLD...
I also found NUMEROUS other smaller splits in the rubber, yet NO dry-rot.
My dealer is checking the new one to be sure it's "fresh". I never did suspect the Shinko brand to be prone to do such things, anymore than any brand of P-rated tire. It's just plain OLD. I can't fault the maker when a tire gets funky after two decades in the warehouse.
I've never worried about a tire's age in the past. We used decades-old truck tires on our Hogs, and most guys had over 10 years on factory tires and they never split... Maybe a little dry-rot, but nothing like this one! I will DEFINITELY watch the tire's ages from now on!
Ride safe,
Leo (now checking the tires AIR and their AGE) in Texas

Wait...0699 isn't a tire date code. Anything before 2000 would have a 3-digit date code (week 6 of 1999 would be "069")...the 4-digit codes were not used until 23000.

Wish I had saved the pictures of the last set of Chinese tires I bought. Not Double Coin though and they went out of round almost immediately and the one that ballooned after less than one year was unbelievable. Commercial Tire Shop and Recapper that I brought them too said even though they were basically new and had plenty of rubber to plane them true that they were of such poor quality that they would/could not use them for anything more than mulch. Set of seven new Chinese 16 ply 245/70R19.5 costing almost $3,000 out in the trash.
You roll the dice when you play with the Chinese brands and the tire vendor that your dealing with becomes even more crucial to ensure that they did not order a custom cost cutter version of a popular tread pattern that just barely meets DOT standards.

I really do not remember. I lost the email with the pictures that I sent out to the short haul truck center that installed them who is now out of business. I almost refused them because they really did not smell right and were off gassing when I picked the rig up. It was almost like they were not properly vulcanized and still raw but the tire shop assured me that it was because it was a new long life formulation that they smelled different. I'll see if I still have any paperwork on them in the rigs service binder which is not here at this location right now. |
