Pari-Motos and flats (was Re: New 650B conversion)

[Toshi Takeuchi]

I'm thinking about using the Pari-Motos on an event ride. The way I
see it, 1 flat/200k is something I could deal with. 2/200k would
be--argh, but would survive. Another guy on the list claimed he got
one flat every 25 miles--at that rate I would be driven to tears. My
other option are Soma Express tires, which ride just fine in my
training rides. I got one flat at mile 3, but haven't flatted since...
Me + bike and stuff would probably be ~185 lb...

1,773 flat free miles on my initial pair of Pari-Motos.

Just sayin...

For me, one flat in over 1500 miles, then several in under 10 miles at
which point I declared the tire done.

Done because the tire was worn out, or you were done riding
Pari-Motos? I guess I'll give them a try and hope for the best...

Done because the tire in question was surprisingly, almost shockingly
thin, and because it was obvious there was something embedded in there
that I was unable to see to remove. Had there been a significant amount
of tread left it might have been worth going over the tire with a
magnifying glass trying to locate whatever it was, but under the
circumstances clearly not worth the effort.

What I did was buy another Pari Moto, used that for quite a few miles.
Then I was going on a self-supported tour on a crushed limestone rail
trail and I realized the back tire on the bike was getting fairly thin,
so rather than risk punctures on the tour I purchased and installed a
set of Lierres, which are still on the bike.

Can you compare the performance of the Lierres to the Pari-Motos or even Hetres?

I've run on Pari-Motos, Hetres, and Soma B-Lines.  I've been riding brevets on the Hetres, which are my favorite in terms of road feel and feeling fast.  I'll probably run the Hetre's on the 400km and 600km.  But if I end up riding a longer ride this year, I'll probably use the Pari-Motos because they are a little lighter and a little faster than the Hetre's.  The Soma B-Lines are just fine and I use them on training rides or shorter brevets; they feel about like Panaracer Pasela's (without Tourguard).

I've had two flats on the 650B tires in around 6000 km.  One was a B-Line at the end of a fleche, I was probably just careless and ran through some stuff on the shoulder of the road.  The other was a Pari-Moto in the pouring rain on the second night of Paris-Brest-Paris and I had pulled off onto the shoulder to do something.  Probably got something stuck in the tire and flatted about a mile later.  I probably have around 1200 miles on the Pari-Motos, about the same on the B-Lines and the rest on the Hetre's.

Not really. Hetres don't fit on the Kogswell, so that comparison is out
(that bike is too different from the MAP for tire comparisons to be
valid) and it's been since before the Mineral WV earthquake that I've
ridden the PMs.

Another voodoo datapoint from me.  My Hilsen with Pari Motos has been parked for a couple months.  I've been using other bikes for the little riding I've been able to do this Spring.  Based in part on this conversation, I decided to use my Hilsen this week.  Since it was parked for a couple months I did need to pump up the tires.  They were both down at about 25psi, and I pumped them up to 40psi in front and 45psi in back.  I did the 1.5 mile ride from office to BART in South Hayward and the 1.5 mile climb from BART to my house in El Cerrito.  That was fine.  This morning I did the ride in reverse, and I had to walk the last tenth of a mile because my rear tire was flat.  I've done the same commute >100 times on my Bombadil with Hetres this year and >1000 times on various bikes over the last 8 years.  This was my first time to walk it.  It's really like voodoo.  I'll get it taken apart and see what the culprit is.  

[William]

Got it fixed.  The size and shape of the hole looked like a glass puncture.  Found the tiny place in the tire where the glass peeked through and blew back out.  Patched it up and I'm rolling again.  Just bad luck in Hayward.

Thanks Bill,

Was the flat with the Foss tubes too? I'll have to hope for good luck
on my ride!

Toshi

[William]

It is a Foss tube, so the patch was a peel-n-stick Fossy patch which is nice.
