Some of you weirdos from ARBR are least tolerable. But your x-posting
is just silly.

Yeah, and you ALWAYS wait for a green light before you cross the
street?

Please don't lump all of us from ARBR together. I blocked NYC XYZ long ago
due to his excessive cross-posting. It really is quite irritating. He only
recently started posting to ARBR... I figured he was a regular from one of
the other groups and had just recently starting adding ARBR to his
cross-posting list.

This will be my last post to multiple groups. I apologize for replying to
all... just didn't know from which group Paul Hobson is a regular.

And I top-post, too!

C'mon, let's have a riot and burn some New York State flags!

The MArathon plus has better rolling resistance rather than using a
tire of same width then adding MrTuffy. The protection is like a foam
sandwhiched bet rubber layers.

On our last trip from Germany to Vienna, some rented bikes in Germany
to be dropped off in Vienna. The bikes were equipped with MArathon
Plus. MEchanic says that they have never had flats on those tires -
granted the roads were clean.

Here's another vote for the Schwalbe Marathon Plus.

Datapoint 1. Over the last 25 years I normally expected 5-6 punctures
each riding season, mainly from bits of wire or glass. That's about 1
puncture per 1000 km. Last year with the Pluses, I had zero punctures in
5500 km.
Datapoint 2. Last summer a friend had zero punctures using Pluses on his
4500 km tour across Canada. (http://tinyurl.com/dvyag)

For me, the miniscule increase in rolling resistance has been well worth it.

Cheers,
Angus

Hiya, folks -- how about the standard Schwalbe Marathon? They come
with the SMGTe.

I personally ride the Marathon 20x1.5's. Knock on wood, have not had
a flat in at least 3 years.
I think the secret is the more pronounced thread pattern compared to
other tires. When you hit a glass bit, it goes in betwen the grooves
and is spit out as the wheel turns. I think tire technology has
imnproved in thelast few years OR maybe just getting lucky

My wife and I did that tour a few years ago. Come to think of it, in the roughly 300 km from Passau to Vienna,(on bikes supplied by the tour operator), not only did we not experience any flats, I don't remember seeing anyone along the way fixing one either.
Of course, we started each day by ensuring they were up to pressure.
For the life of me, I don't remember the brand of tire though.

I ride them too (on an SMGT and a Brompton). My other half rides them
on a Nazca Fiero Tour, having found the security better for her than the
speed of Stelvios.

So far I've had two punctures over, oh, about 5 years. One on the Brom,
one on the Streetmachine. Covering a lot of miles, and broken glass.
They're good tyres, I'd only change to the Plus if I was in an area of
Total Puncture Hell.
