Yet, you pumped it up to 95 psi, and you seem to say it was a "snakebite" while not hitting anything. I really think this is a question of over inflation or at least wrong tubes/too small tubes, or it could be a combination of all the above. If you didn't over inflate the tyres themselves, are you then sure that the tubes themselves aren't of a too small diameter?

Rifleman

When I left to go riding my tires were at 85 psi when I got home I aired up to 95.My inner tubes are the correct size.

Rifleman

I think that awesome German quality went way down when they started having there tires made in Indonesia.

SmallFront

Sure, it's the tyres in general having a problem, and those of us who doesn't experience any problems anywhere near the problems you have are just plain lucky.

It can't possibly be user error, when you are getting "pinch flats" on flat tarmac, and overinflate to 95psi or anything of the kind. It must be the tyres that are at fault.

Rifleman

What are you a factory rep trying to cover your crappy product

SmallFront

Just because I disagree with you on you putting blame on a product where it seems the only logical reason is user error (getting "pinch flats" on a supposedly properly inflated tyre on flat tarmac!?) doesn't mean I am then a factory representative. Only someone who is in denial would resort to such accusations in lieu of proper arguments.

Your explanations point to user error, not product flaws. If they were even near as bad you try to make them out to be, I wouldn't use them, nor would anyone else. They would have to be retracted from the market. But hey, your one-day experience with "pinch flats" on flat tarmac and overinflating to 95 psi, coupled with the simple assertion that your tubes are the right size, is enough to prove that the tyres are at fault, and that my (and other's) years of good experiences with these tyres are just plain luck, because they are so bad they will make the tubes collapse within a day of usage.

But hey, I must be a "factory representative", right?

Rifleman

My apologies,not trying to piss anyone off but I didn't ride after I put 95 psi in the tire,it flatted before I had a chance to ride again

Rifleman

I read where other supreme sidewalls we're failing since production began in Indonesia and it has Schwalbe stumped.Im just putting 2 and 2 together

SmallFront

Doesn't matter, you still claimed that you had pinch flats while riding on flat tarmac, which to me screams "user error!". It can be a variety of things, but I don't see how a supposedly properly inflated tyre can give you pnch flats on flat tarmac, or what appears to be pinch flats (blow outs can look very similar). And your resolve when you got home? Overinflate it to 95 psi! Yes, and when confronted with that and possible reasons, you claim that your tubes are the correct size, while continuing to blame the tyres. In what universe can you pinch flat a properly inflated tyre on flat tarmac, unless you are massive in size (and I do mean massive - these aren't skinny tyres)?

Rifleman

240 pounds and never had a problem with Continental touring plus tires

SmallFront

A sidewall failing is one thing. What you claim to experience and continue to deny is your "pinch flats" and how they also developed a flat while you overinflated them, only to find a shard of glass or metal afterwards on the inside of the tyre. The sidewall failings of others (there are a few out there) is not related to your problems. Have your sidewalls failed?
You are not putting two and two together. You're taking one set of problems that a few has experienced, and then claim that your problems which are of an entirely different kind are the same - which they are most definitely not.
Next time, try "underinflating" the tyres slightly. Aim for, say, 78 psi on your meter, as I suspect over inflation, and it could be that your meter measures low, resulting in overinflation.

Rifleman

I guess all those who have had sidewalls fail guess that was their fault also

SmallFront

The point was that if you are even in the ball park of normal, it would be impossible to get pinch flats on such a big tyre if they are near their max psi - unless they are overinflated and aren't really pinch flats. Your red herring about others having had sidewall failures is nonsense. It doesn't matter, because that is not what you are experiencing.

Rifleman

I've got a piece of glass in my tire where did that come from

SmallFront

Sigh! You have not had a sidewall failure. You have had what you claim to be "pinch flats", and you have experienced how when overinflated, it will loose air when you fail to remove shards of glass of metal between the tube and tyre. That last bit is all you. The first bit I suspect are overinflation, or tubes of too small a diameter (resulting in the tube being overinflated, while the tyre is not).

SmallFront

How the hell would I know? It can have come in when you "fixed" your flat, or it could have been the cause of the flat in the first place. No tyre is puncture proof, nor does it magically repel foreign objects from entering. Maybe if you had checked for such things when swapping tubes/fixed the flat, at least the second flat wouldn't have occured.

Rifleman

Whatever.Tell you what,your ever in the U.S. or I in Copenhagen,we can hash it out over a beer

SmallFront

Haha, no: You can't be talked into checking for foreign objects while fixing a flat, nor to try to "underinflate" the tyre according to your meter, or anything else that would be prudent. Instead it is the fault of the tyres, because some people report some entirely different problems with theirs.

You don't need someone to "hash it out with over a beer". You need someone who knows what they are doing to show you the proper techniques of tyre inflation and fixing flats.

Rifleman

Ok

lining up your valve with an identifiable mark on the tire can really help for knowing where to look in the tire for a hard to see imbedded object that can be overlooked and cause another flat in your new spare tube.

knowing where your tube is positioned in the tire is great if you can see where the hole is in the tube, then you can look specifically in that area of the tire and really inspect carefully if the offending object wasnt obvious from the get go.

often tires will have a sticker or brand name or something, you can also use a grease crayon or whatever to make a clear mark on the tire on one side for you to line up the valve with.

after visually inspecting the outside of the tire, and after taking out the tube (you can lay it down in the same direction and position you took it out from tire) use your finger to feel for things pushing through the inside of the tire (dont cut finger) after taking a peek also.

bottom line is if you put a new tube in and the glass or wire is still in the tire, you'll get another flat.

and yes, pinch flats happen when the pressure is so low that when you hit a pothole or whatever, the tire/tube compresses so much the rim pinches the tube. Your description of what happened doesnt bear that out, unless your tire was deflating beforehand due to a piece of glass or whatever. At proper inflation a pinch flat wont happen.
also, do you check your pressures regularly? If not and not for a long time since you checked, and your pressures were really really low, being 100 lbs heavier than me could have resulted in a pinch flat. Only you know these answers

Rifleman

Yeah I line my tires up with usually between words or symbols on my tires.i checked the inside on tire and rim before replacing the new tube. I'm going to head to the bike shop tomorrow let them have a look see what they think I'll update then appreciate the reply though.

LeeG

Which has nothing to do with the tire but is a leaky tube. Did you install with tire irons or by hand?

LeeG

You are putting anecdotes together. One more time, light tires will have light casing. It makes for a comfy ride and less durable sidewalls. That doesn't mean weak or flawed. It means not ideal for rough roads where sidewalls can get scraped. Pinch flats do not happen without sharp impacts. I'm guessing a couple possibilities, installing a tube with a fast leak so you actually did get a pinch flat, two holes one above the other on the side of the tube. You installed with tire irons and pinched the tube enough to weaken it.

Rifleman

The sidewalls are so easy on easy off I don't need tire levers.Some guy who was at the
bike shop the same time as me, said give Schwalbe inner tubes a try.He said there sizes were much more accurate and he thought that might help over Chinese made inner tubes.He also said don't rely on my floor pumps pressure gauge and use a hand held gauge like SmallFront mentioned the other morning.Ive got a few tubes ordered.
