2145.1 | no easy way out. | WLDWST::SANTOS_E | | Fri Dec 20 1991 10:23 | 8 |
| If it sounds too good to be true it probably is not. My best
commuting tires for the rear was a specialized K 4 x28mm width I got
1,800 miles on it until i broke the sidewall on a rock . another good
one is the michelin select , its a tough tire with 3 widhts available
and for $7.95 through nashbar its great. the only draw back with it
for me is that it scares me when I have to turn fast on wet pavement
for it's a bald tire with small side grooves.

I wouldn't worry about that. I've read several places that
tread on a bike tire makes no difference for wet traction.
Makes sense too. It's a lot different than a car 'cause the
contact patch is so much smaller and at so much higher
pressure.
If you plus your bike weigh 200 lbs and your tires are pumped
to 100 psi, you're only going to have a 1 square inch contact
patch on each tire. The 100 psi over such a small area
effectively "squishes" out (nice technical term) any water
buildup. If you have a 3000 lb car with 30 psi tires, each
tire will have 25 sq in of contact, and at a much lower
pressure. Big difference.

2145.3 | Go with the kevlar for puncture resistance | NCPROG::PEREZ | Looking for the Mary Poppins attitude | Fri Dec 20 1991 22:15 | 17 |
| Since this has wandered off into tires...
I disagree about the Michelin Select - its IS a great tire, and rides
nice and all that, but it is easy to puncture - especially when fully
inflated... I had a brand new set, had 2 punctures in 2 days... END
of the Michelins.
Rather, I'd recommend one of the Kevlar belted tires. Something like
the Schwinn Super Record VR or one of the kevlar belted tires in the
Performance catalog. They only ran about $12.00 last summer. I've got
over 4000 miles on kevlar tires and have NEVER had a flat due to a
puncture. Even when riding over visible glass. I like them enough
that I put a set on my wifes bike because I got tired of fixing flats
on her bike.
re: .0: I think kevlar belted tires would be a big step toward your
goal of not having to fix flats in cold weather!

2145.4 | AVOCETS... | WMOIS::GIROUARD_C | | Mon Dec 23 1991 06:42 | 9 |

I had an Avocet K20 on the front for 11k+ miles. I took it off
voluntarily because it was cracking quite severely...
I had very good look with them, but I switched to Conti's and
they've done me fairly well (one flat all last season - during the
Andover Race naturally - the first race I did)

2145.5 | Thanks for replies, will try kevlar belted tires | MSDSWS::HAYWOOD | | Mon Dec 23 1991 10:10 | 18 |

Thanks for all the replies!!!
I had thought about kevlar belted tires, but read (I am sure in this
notes file) that they have a harsh ride, and to just live with the
flats. Sounds like maybe they are improving their ridability. I think
I'll try the Specialized Transition with Kevlar belts. That's what I
have now (without the kevlar) and then I can feel for a difference with
the belts added.
re -.1
11k+ miles on a tire is quite a feat!! Where I ride the tires get too
many cuts in them to last that long. Maybe I should be more careful.
Thanks again,
Terry

BTW, another vote for Continentals. The ones in use now on my primary
wheels must have about 10,000 miles on them: "the tires that wouldn't die!"
A lot has to do with how hard the rubber compound is. Years ago
Nashbar's $5.95 tires had the same sort of longevity - rode as well
and lasted four times longer than "the higher priced spread" - the
$10 and $15 brand-name tires. I suppose that the price you pay is
a slightly harsher ride (as with Kevlar belting).

| But, John, I'm going to let the cat out of the bag. All tires last
longer where you ride! There's a real difference between the Carolinas
and New England, ayup.

| re .6
10k miles out of a tire. That's not a rear tire is it John? I only get
about 1050-1200 miles out of a Avocet K20 on the rear.

Strange but true: it was (and is) a rear tire - a Continental 23mm
Super Sport; the front is a 20mm. I have seen tires wear out as fast
as 1500 miles - I won't assume outright that it's planned obsolescence
on the mfr's part, but there's got to be a middle ground between
"wearing like iron" and "subsidizing the tire company in a major way."
Of course, Mark's excuse is all the wear and tear grinding up the
Rockies and plummeting down them. :-)

PS: Ed is right, I guess. When he was down here for the Thanksgiving
Centuries, he had to explain the concept of "Ice Heaves" to an
unbelieving peloton. :-)

| The Avocet K20 tires have really soft rubber (that's how they
get any traction with that slick surface) but they wear out in no
time. I sure won't bother with them any more.
My front tires (even the Avocet's) have lasted till the sidewalls
begin to crack but I don't think I've ever gotten more than 3
or 4 thousand off a rear tire.
The kevlar gives a harsh ride, but I feel it does reduce flats.
But the most important thing is to keep clinchers pumped up really
hard to avoid snakebite flats.
But you want a harsh ride? I have a thorn proof tube in my rear wheel
for use on the wind trainer (since it's the only way I know to avoid
the **** thing giving me flats!) God that wheel is heavy! But if
I'm plodding along outside on streets screwed up with sand and salt,
with heavy clothing and my nose running what's the difference. And
I don't have to dink around changing wheels to ride outside or use
the trainer depending on the weather.
