I have Continental sport 1000 tires. The tread is still in good shape,
but the tires are 3 years old. Is it a good idea to replace the tires
due to the age of the rubber?

Michael

yes! They're $5 tires, give me a break.

No, It's a good idea to replace the tire because it's a Continental.

I see that you a few usless answers so I will atempt to get you some useable
information.

If the tires are still in good shape there is no need to replace them. When
my back tire wears out I move the front tire to the back and put a new tire
on the front.

Since I need 27 x 1.25 tires, do you have any good suggestions? I'm more
interested in puncture resistance that tire weight.

Hi, seeing as the other two replys, up to now, are worthless, I'll
give you my opinion.
Usually the decision to replace tires is based on wear, which can
often be determined by mileage. Of course condition and age are also
worth considering.
If they are full of cuts and have had numerous flats replace them. If
they were old enough that the rubber was dried out and/or cracking
replace them.

The tires you have often come with new bikes, they are an inexpensive
tire. Not all Continentals are alike. Some have very thin side walls,
others like the Ultra Gatorskins are quite flat resistant.

Do you want new tires? If so, go ahead and replace them. If they are
not causing you problems there is no need to replace them, until they
are worn out.

If you do decide to replace them, if price isn't a concern, consider
the Continental Ultra Gatorskins, or if price is a concern then

I had a set of the Prima 2 Plus on my older bike and had no problems.
I am now running Gatorskins on bothof my bikes.

I was coming to the conclusion that I want to go with the Gatorskins.
The sport 1000 seem to go flat on rather little bumps. Thanks.

In my opinion, replacement is only needed if it's cracking and/or
flaking away from the cords. Modern bike tires are safe to use until
they wear out or start to fall apart, regardless of age. The only
instance in which I might recommend against that policy would be for
long-distance touring, and in that situation it would be foolish not
to be carrying spares anyway.

The Gatorskins are a nice-riding tire, far better than the Hutchinson Excels
I had before. As for its flat protection, your eyes are a much better flat
protector than the tire might be. If the road is wet and you have a lot of
glass, forget even trying your luck.

No, that's a waste of money. There are two resons to replace a tire:

•The tread is worn thin so it gets punctures more easily.

•The fabric is damaged so that the tire is misshapen or lumpy, or the
tube bubbles through a gash.

There's not actually much difference in puncture resistance among tires
of similar tread thickness. You haven't said what sort of things you're
getting punctures from.

If your problem is small glass slivers, there may be some slight benefit
from a belted tire.

If it's nails or the like, tires vary in nail resistance in much the
same way as different types of t-shirts vary in bullet resistance.

By the way, it is a dangerous habit to translate tire sizes back and
forth between decimal and fractional notation. As it happens, there are
no decimal sized 27 inch tires, so calling it "27 x 1.25" isn't as
dangerous as it would be if it were, say, a 26 inch tire.

Whenever you see two tires where one is marked with a decimal and the
other with a fraction, you can be sure that they are _not_
interchangeable, even though the nominal sizes may be mathematically
equivalent.

See: http://sheldonbrown.com/tire-sizing for details if you care.

If you do decide to replace your tires, we have an excellent selection
of 630 mm/27 inch tires, see:

Hi, if you are getting flats, from hitting bumps, as opposed to
punctures, then you are not keeping your tires properly inflated.

Are there often two holes in the tube, like a snake bite?

Bicycle tires need to be checked often, I check and top mine off,
before each ride. If you are a heavy guy, inflate to recommended max.

As someone else said, the best flat protection is being alert, and
then avoiding, as much as possible, glass, potholes, etc.

Nashbar has the Gatorskins in your size. Although for the best price I
have seen, try Tires Direct - $27.95
http://www.biketiresdirect.com/productdetail.asp?p=COUGA

Tires Direct offers a 60 day road hazard protection for $5 per order.
Even adding the hazard protection, the tires are still the lowest
price that I know of.

Not unless they look bad (e.g. the threads are breaking loose because
the sidewalls have dried out) Car tyres that aren't used are said to be
good for 6 years.

I think part of the problem is that the original tires on the bike were
27" x 1". Even though I keep the pressure around 100 psi, the
Continental sport 1000 1 1/4" tire's weak casings let the tube get
crushed between the rim and casing.

Would you replace the tires on your car after three years due to the
age of the rubber?

For the amount I drive, I might have to replace my car tires due to
environmental degradation instead of wear.

Yes.

I replaced my motorcycle tires every year. My RX-7 tires every 2 years,
and my SUV tires every 4 years.

I know that the day a tire is made, it starts to degrade. I replace my
motor vehicle's tires not based on tread depth, but on the type of
rubber used in the tires I buy. I buy tires for road grip, so I
understand that they wont last 10 years or 100,000 miles.

get another tour out of them.
