pfff.....

I like how they used a TUBE for the repair. Might as well just use a tube tire in the first place.

Cheers

Why? So that you can get five times the flats as a tubeless setup gets?

Let me ask you again - why do you suppose that every other rubber tired vehicle has changed to tubeless?

You're beginning to sound like Joerg. "Why don't bicycles have chains as
strong as motorcycles? Why don't bicycles have integrated charging
systems and heated seats and power windows? Why don't bicycles protect
us from the rain?"

The requirements are different, so the engineering is different.
Bicycles don't have spare tires already mounted on wheels inside their
trunks. That alone is very significant.

His question is an exaggeration. Every rubber tired vehicle does not
use tubeless.

I was looking at the wheel chairs in the Hospital the other day and
they have foam filled tires.

I came across an article that stated that many "Container" carrier
trucks are still equipped with tubes.
https://www.quora.com/Why-are-tubed-...ses-and-trucks

Then I came across the Goodyear catalog for aircraft tires and see
that the "standard" tire for the 747 is a tube tire.

I could go on (and probably on) but it is obvious that the statement
that "every other rubber tired vehicle has changed to tubeless" just
isn't correct.

Or perhaps it is a matter of "every tire that HE KNOWS ABOUT" is
tubeless which says something about his qualifications as a tire
expert.

John, do you even bother to read the stuff you are posting? It plainly states in that article that they don't have tubeless tires because of the expense of upgrading to new style tires and rims.


Certainly I read it and I did read that the cost was the deciding
factor... but the other poster wrote "why do you suppose that every
other rubber tired vehicle has changed to tubeless?", which I was
responding to:

It seems to me that if a significant number of vehicles have not
converted to tubeless, for financial, or whatever, reason that to
blatantly argue that "EVERY OTHER RUBBER TIRED VEHICLE HAS CHANGED"
is simply an example of ignorance of the subject. Hardly a statement
that someone that was really familiar with the subject would make.



If your argument is based, as most here appear, to be that you have an old bike for which conversion would cost more than the worth of the bike why the hell don't you argue THAT instead of using the phony arguments that they would be difficult to repair if you got the same sort of flat that would also make a tube tire worthless. The dumb-ass comment that you could fix one of these slashed open tires with a candybar wrapper is pretty inane. Or the claim that they don't get as good a performance when even the testing shows the theory of rolling resistance being less on a tire with less mass to e true as it is in every other case.

I made no argument. I simply called attention to the fact that the
individual that stated "why do you suppose that every other rubber
tired vehicle has changed to tubeless?" simply didn't know what
he/she/it was talking about.

An expert in misinformation, one might say.



Look, I've been riding for 40 years. I've had a lot of flats. I have never successfully repaired a slashed tire with either an innertube section or ever found a candybar wrapper that would possibly hold anything together against the inflation pressure of a high performance tire.


slash ~ verb common
1. cut with sweeping strokes; as with an ax or machete

Do you mean that someone attacked your bicycle with a machete?

Or did you really use the term to exaggerate your description of the
tire damage and make it sound much worse then the actual?


As a sailor I could also repair sails with heavy needles and nylon string.
I'm pretty sure you could sew up a tire well enough to make it home
against inflation pressure but again - that would work equally well
with a tube or tubeless tire.

As a Sailor (live aboard for more then 10 years) I might repair a sail
with needles and thread but string is what you tie up Christmas
presents with.

Since Joerg complains of sidewall slashes from the way he rides I could understand his arguing against it. But 10:1 his sidewall failures are punctures that a tubeless setup would allow him to continue riding.
