I had 2 of them front shinko 011 tires Fail on me on my st1300.Will not use it again!! Big bubbles on tread, were only half worn
Well, you may be right Larry, because I can't find any leak elsewhere, twice now. However, I have checked for leaks around the bead several times with both tires and have not found any.what your not taking into consideration is when the tire is starting to come to the end of its life, the tire is thinner, and more flexible, and has less strength and support on the side wall.
They can squirm around and start to leak in places that they didn’t in the beginning of their life.
I have seen this happen with several different brands of tires, and would not imply it was a Shinko brand tire problem only.
Andrew, what method are you using to inspect/look for leaks with? Just curious.Well, you may be right Larry, because I can't find any leak elsewhere, twice now. However, I have checked for leaks around the bead several times with both tires and have not found any.
A worn tire in and of itself is not a cause for a bead leak in my opinion and experience. A tire won't leak around the bead seat simply because it is worn, regardless of how worn it is. There needs to be a cause for that leak. If normal tire wear is the cause it is unique to this tire and a problem with their design as I have never experienced or heard of a worn tire by itself being the cause for a bead leak without any other influencing factor.
Usually corrosion, dirt or bead damage is the cause of a bead leak. This not the case with either of these. I clean both the rim bead seat and the tire bead of the new tire at every tire install as a matter of course. After having this experience the first time, I examined the bead seat and the tire bead after removing the tire because I wanted to know the cause of the leak. I found nothing of concern or that would explain the leak. With the second set I was extra diligent in making sure that there was no contaminant in these two areas specifically because I did not find a leak the first time, and did not want a repeat of this scenario. When there is a leak that can not be found the bead seat area is the most likely suspect. Because of this I made sure that both the rim bead seat and the tire bead were spotless, and tire paste was used.
It is almost as if when the tire gets worn below a certain level the remaining rubber is just porous enough to allow air to escape. I hope not, because other than this problem I like these tires and the price is good.
Keep throwing ideas at me. I'll keep checking all suggestions to see if I can find a leak until the tire needs replacing. If it is something that can be checked only when the tire is removed, I will look for it then.
I've only run 3 sets of Shinko's on MY ST with no issues, other
To update, I had to resort to an old trick to find it but I think that I have found the cause of the leak with my Shinko Verge 011. The little rubber nibs that are left from the tire mold are present on every tire, but I don't think that I have ever seen them on the bead seat. Shinko put 12 of them right on the bead seat on each side of the tire. That creates 24 potential micro-leaks. These leak so little that they are hard to detect but collectively they create noticeable loss in air pressure.I have checked the valve and around the bead and no leaks found.
Because of the leak with the second Shinko, I exercised extra vigilance making sure that the rim bead seat and the tire bead were spotless when the third Shinko was installed.
I have never bothered to cut them off because there was never any need to. This has never been a problem with any other tire be it motorcycle, car, tractor, golf cart, etc.. There is no reason for these to be a problem with this tire either, but they seem to be. Obviously badly designed.Wow, you mounted the tire before trimming all those off?
Guys laugh at me because even on my trials tires, I trim all those off of the tires.
They are needed when making the tires to release them from the mould.
I guess being OCD when mounting tires helps.
Don't know what happened to your tire but what I have seen is cuts or rips in the bead area from a poorly installed tire. Air seeps through the cord and causes a bubble. Other things could happen.I had 2 of them front shinko 011 tires Fail on me on my st1300.Will not use it again!! Big bubbles on tread, were only half worn
It is not the presence of them that is silly, it is the fact that their presence causes a leak that is silly.They are on Michelin, Pirelli, Bridgestone, and just about every other tire out there.
Like I said, I trim them off kinda like an OCD right of passage, but I have found them causing slow leaks on the bead….but only if you check them in a water tank after you mount them, which almost nobody ever does.
I would think it’s kinda silly to call it a design flaw for this one brand since they all have them.
Because I am satisfied with these tires in general doesn't mean that I am incapable of acknowledging that they do have a flaw. Viewing voicing that simple acknowledgement as a witch hunt seems a rather strange assumption considering that I just went out and bought yet another set of these tires, my fourth I believe, but you couldn't know that.Starting to sound like a witch hunt for that tire brand
