Does anybody make 37-630 tires?

[bob prohaska]

I just ordered some Kenda tires for my old Cannondale in
size 27 x 1 3/8 inch. The goal was to obtain a somewhat
softer ride on the very rough pavement in my area.

When the tires showed up they were marked as expected,
but are only about 27 mm wide, or slightly _under_ an
inch and an eighth.

Does anybody still make road-style 27 inches tires in
wider sizes? The best I have found is 27 by one and a
quarter, and that's nominal; I haven't measured them.

Thanks for reading,

With which rim width did the Kendas turn out 27mm?

If the pavement is just rough, but not glass-littered, I'd take 1 1/4 Paselas.

Some other Panaracers are "1 1/8," but 3kPa pressured seems more
curbless-city style than road-style.

I don't know about 1+3/8 27" tire but check to be sure there's enough room for them to fit. I converted an old Cannondale with Shimano 600 stuff to 700C so I could use tires wider than 1+1/4" about 35mm. IIRC the 700C tires I TRIED to use were 38mm with knobs ie they were street tires; but they would rub the chainstays.

Godd luck and cheers

I believe that Schwalbe used to have a 27 x 1.5" but no more. The best
you can do now is 27 x 1 3/8 (37-630), i.e.
<https://www.amazon.com/dp/B001C6DC1A>. One review says that the width
is accurate.

There are some NOS (New Old Stock) 37-630 tires on eBay.

21.5 mm inside, about 23.5 outside. The rims to be used in
service are about 22.5 outside, but on those rims a Continental
1 1/8" tire is wider than the Kenda 1 3/8" tire, so the Kenda is
notably underwidth.

Those would work, but don't seem obviously better than the
1 1/4" tires I can get locally.

[The page cited comes up in Japanese, I can't make heads or tails of it]

The local shop that ordered the Kenda tires has agreed to exchange
them for Continental "Ride Tour" tires in 1 1/4" width. While nominally
narrower, I think they're apt to be much like the 1 1/4" UlraSports I've
been using, which is tolerable.

It would be helpful to know which manufacturer's width descriptions
are to be believed. Clearly not Kenda's.

Thanks for posting!

In (many) years past I used 1 3/8" tires on the bike and they just
barely fit. It was necessary to shave off one outermost row of knobs
on cyclocross tires to fit, but that was enough.

27 by 1 3/8" is the widest that will fit, even with a little surgery.
Knobbies aren't really helpful in my application, everything is paved,
it's just that the pavement is wretched.

I'm slowly coming to accept that 1 1/4" width is the best to be had.
My hope that somebody knew of a 1 3/8" slick are fading fast.....

Thanks to all for your counsel!

On one of the various bicycle discussion groups I read a comment about
the Kenda 27" x 1-3/8" being about the same width as the 1-1/4" but
were "taller".

"Ride Tour" 32-630, Conti #0101161, is a 0.57 kilo, 80 PSI, anti-puncture
rubber layered, city/trekking tire, made in China. I hope a fine,
generator-less front hub can make up for the added rolling resistance. (SCNR)

It turns out that all three tires I measured were roughly the same
width: Continental Ultrasport in 1 1/8" and 1 1/4" and the Kenda
1 3/8". None came close to the ISO section widths. If the height is
different, it isn't enough to notice easily; I didn't make any careful
measurements on that score.

The bike shop folks all say "buy new wheels" but as long as the old
ones can be kept reasonably true I'll just live with what I can
buy. The point of my riding is transportation and exercise, and all
the tires work well enough for that. I wanted a bit of comfort, is all......

Thanks to everyone for reading and guiding.

The pair I got say "India".

They'll serve my purpose well enough, but they're no softer riding than the
UltraSports and I probably won't buy them again.

Didn't Sheldon have some comments about tire specifications versus
actual measured sizes?
Or maybe

Right the basic model Kenda 27x1-3/8 is a knobby tread on
what seems to be the same casing as their basic 1-1/4 street
tread tire.

We have skinnier, lighter, finer fabric, Aramid lined etc in
630mm but nothing fatter nowadays.
