I hate it when I have to throw away a tire that still has new-tire
whiskers sticking out from the edges of the tread, but that's what I
did.

Maybe you should ride more.

The tire is 8 years old and you're moaning about throwing it away?

"Audi, BMW, and Volkswagen recommend replacing tires after six years,
regardless of tread wear. The British Rubber Manufacturers’
Association said in June 2001 that unused tires more than 6 years old
should not be used and that a tire should be replaced 10 years after
manufacture. Roadside checks led the U.K.-based Tyre Industry Council
to warn that tires can dry with age, leading to tread separation."

If so, probably a CYA after the SUV rollover mess they had.

precisely what i was getting at. a vehicle should NOT roll because of a
flat. period. ford knew it did. but they did the math on the costs of
redesign and chose to ignore it as a cheaper option. and they bribed
their way out of trouble when it eventually came.

there should be jail and giga-fines for the "executives" that made those
decisions. /way/ worse than enron.

It's a chopper. An extravagant one, at that. IOW, even when it's
operational, it doesn't see pavement every week, and when it does it's
for short forays. I have an adult-size Big Wheel trike that has
traveled a lot more miles than this chopper.

Anyway, there are about 20 bikes here, and many of them are good
practical rides. I can't wear out the tires on all of them. I'm
doing well to wear out the tires on some of them, and I do.

But as to the ravages of the Central Texas sun-- when I was 20 and
riding 300 miles a week, my Turbo S ATBs and my Fat Boys and my Fas
Grip Citys all had tread left on them when the sidewalls grew hairy.
And I only had one bike then, and I kept it inside when I was at
home.

Folks who only ride on pleasant Sunday mornings when the temperature
is between 60 and 85 degrees may fail to appreciate the prevailing
conditions of a place where it can exceed 100 degrees every single day
for almost three months running.

Sheldon Brown used to point out that bike tires were still good for
decades if not worn out or damaged, and I agree. I have NOS Goodyear
tires for 20" bikes that are still soft and grippy after around 40
years in the wrapper. I'd be a fool to ditch them just because car
tire makers want to sell more car tires more often.

You're probably right. I hear you're the expert on all things bicycle.

You don't need to read Ed Dolan the Great. Just read any of Mr. Sherman's

Hell?

Pleasant for riding is 50 to 65°F.

Here's a photo of how bad this tire is:

and I'm not complaining, really, just a bit puzzled
over what makes a good tire (many of which don't
seem to last anymore) and this old tire that
keeps going even when falling apart.

Understand that "accountants" force manufacturing to make choices
based on economics. Having the tires fail "six months" after you buy
the rest of the machine, does not denigrate the rest of the machine,
and will not lose customers.

I'm surprised car manufacturers don't ship their cars with four tiny
spares like they put in the trunk now...

My two cents.

before wear??? that's another incredibly revealing and fredly chalo
statement!

why do you hang out on a "bike" newsgroup chalo? "circus clown

I live a couple days' ride north of Chalo and I have to back him up on
this one. Between the UV and the Ozone tires don't last very long
here. I have had to throw away tires that had less than 500 miles on
them because the carcass had split from weathering and pollution, in
all areas of the tire, tread, sidewall and near the bead. I have had
tires go bad that I though were whitewalls until I demounted them and
discovered a black bead that faded to chalky white. TX is running neck
and neck with SoCal as the most polluted area in the US. SoCal levels
are a tiny bit higher, but TX are over a much wider area.
