32mm Supreme flatted on the way home from work yesterday. It was the
1st big rain of the season which always makes for interesting
conditions, so not a huge surprise.
What was a surprise was what I found when I took the tire off. The no
tube gunk I had put in the tube last winter had leaked into the space
between tube and tire and made them one. No way to replace the tube. I
found the leak - a 3/4" slash in the tire and fairly large hole in the
tube - and peeled enough of the tube off the tire to fit a patch
later.
In any case I intended to replace the tire next time it flatted, so I
installed the 37mm Supreme I had been saving for that purpose. Since I
still had a 32 on the front, I assumed I would then need to raise the
nose of my saddle. 2nd surprise, the nose was higher with the larger
tire on the back of the bike. Go figure.
A small adjustment to my sloppy fender position and I was good to go.
New tire feels nice and cushy compared to the old one. The ride to my
office took a bit longer than usual this morning, not sure if that's
because of the rain or the lower pressure (70 vs 80-90 psi).

Why do tires always get flats with the first good rain of the season? Is it just to remind us that Nature is always lurking out there? Some kind of strange magnetic resonance between rubber, rain, and sharp things??

I have hypotheses about this:
1. Rain washes debris into the traffic lane, which makes it available for tires to run over.
2. The water acts as a lubricant to facilitate penetration. It may also serve as an adhesive to stick the debris to the tire tread.
3. Any debris that is embedded in the rubber may be repeatedly pressurized as the weight on the tire squeezes water into the hole, forcing the debris to penetrate deeper.

Am in agreement with Jim on this. A number of years ago, rode my long-departed Atlantis in a early season rain/late season snow ride. About 60 miles. Ended up with three flat tires. And of course, only two spare tubes. Rode the last couple of miles on a flat tire. Sadly, my progress was so slow otherwise, it didn't make that much of a difference. (FWIW, the tire was a 26" 50mm Big Apple)
(Also reminds me of my dream bike - a 61cm Atlantis designed for 26" wheels.)

How close would a repainted LHT be to this? You can get them in all

sizes with 559 wheels now.

I happen to have a 58cm LHT (closest in size due to different top tube length). With 26" wheels. The ride is different enough to wish for the Atlantis.

I also had a flat in one of the first really wet rides I did last week. Jack Brown Green, so no surprise. It was a small glass shard. I replaced the rear tire with a Jack Brown Blue for the rainy season, and left the front Green. I never get flats in the front tire. KOW...
