Solid tires - they are back...

Last time I tried some, there were a few problems.

Firstly, I wasn't able to ease it onto the rim without snapping a few of the
tension cords - the tyre came off if I bumped up a dipped kerb at an angle.

Secondly, the tread wore away in no time flat, exposing the internal foam
composition - rolling resistance had a whole new meaning squelching along on
waterlogged tyres.

Based on the website, Tannus is very enthusiastic about showing
off the bright color choices for the tires. But it doesn't
seem to think rolling resistance data is worth mentioning.
That makes me skeptical.
They do say that the same energy necessary to get a pneumatic
tire (what tire, we don't know) up to 30kph would get the Tannus
up to 29kph. There is no discussion of ride quality, cornering,
wet grip -- or anything other than "it doesn't flat, and it is
not too much of a pig."

The telling point is that it took the author 1 hour and lots of
swearing to get the tire on the rim. I probably spend less than
that fixing flats over the life of a single tire. ...


Then you have probably never mounted Gatorskin tires on flat Mavic
racing rims. I could only do one a day because my fingertips hurt so bad.


... My commuter
also gets different tires over the course of a year to cope with
different situations -- I'm on the big rubber now, but I see no
reason to ride a piggy tire during the summer. I would hate to
wrestled with the solid tires when the weather turns bad and I
want something fatter, skinnier or with studs.


You can get some pretty decent flat protection these days without
sacrificing much in ride. I haven't had a puncture flat in years
using Spec's turbo pro tires and they handle pretty well. I had a
couple snake bites a couple of years ago after a sizable pothole
put a cut in the tire that I didn't notice but beside that, no
problems. Why bother with a solid tire?

I was thinking the same thing. My flats are very few and far between.
I can see solid tires if you're riding in a debris field all the time
but to me solid tires are just turning the clock back 100+ years.


I have super-thick tubes in there. It was the only way to curb flats in
this area. Goat head thorns are the main reason:

Excellent! You'll see more wheels! Looking for the up side for you.

Sensible people carefully use a tyre lever to help a tight tyre on to a rim.

Put one on your trainer stand wheel to Up the workout factor

also OK on the Garden cart ..
but the air in that wheelbarrow tire is still important.

still have 2 700-35 & 1 27" hanging in storage from the 90s/ if anyone wants some.

'captive air'

In our industry this sort of thing comes and goes, at least
for a hundred+ years now. In the auto business, half baked
ideas become mandated.

Like "Air Bags" that I understand have killed a number of people and
are now being replaced, by some manufacturers, in a big recall program
with an "improved version" that is said not to kill people.

I would have to question whether the "new Tires" are actually better,
or just "new".

There is more than just make and model of the comparison tyre missing
from that.
How fast was the acceleration, what pressure was in the comparison
tyre, what surface conditions was it measured on, what weight was on
the tyre, and was it on the flat or a gradient are also missing, and
are all needed to make any real comparison.
It's unlikely to have been a good tyre in the first place (why would
the publish an unflattering comparison?), so I reckon the absence of
the rest is not an accident.
So we can conclude that they are only slightly worse than complete
****!
I've had experience of foam-filled tyres on wheelchairs, and they are
universally far worse than even the notoriously heavy running
Marathon+s that I replaced them with on the "outside" wheels. I have
some better ones for indoor (and high quality outdoor) use, which are
far better than the Marathon+s.

There is no discussion of ride quality, cornering, wet grip -- or anything other than "it doesn't flat, and it is not too much of a pig."

A military enemy will usually cause woundings if possible - wounded comrades
are a burden on the others.

Conversely; airbags kill you so you don't smash your head on the windshield
and get brain damage and become a burden.

I have Gatorskins on some MA3/Open Pros, and they're a breeze to get on and off. Nothing compared to first generation Turbos on E2/ModEs. For those, I ended up using the VAR tool: http://images.cdn.bigcartel.com/bigc..._jack-1-wm.jpg
