3 Inches?

Hi all,

It seems to me that some, if not most, tyre manufacturers can’t use a
ruler when they are measuring the widths of their tyres. What I mean is
that there seems to be plenty 3.0 tyres out there that just ain’t 3 inches
wide… or even close. I’ll agree that the 3.0 measurement may well mean
the fork needs a 3.0 clearance for the tyre but when some (like my Halo
Contra) are actually only 2.5… Grrrrr!!!

The Arrow Racing web site does give the “static width” for their tyres and
list this as being 2.7 for the PrimeWide2 24x3. I haven’t seen any other
company do this. Well done Arrow!

So… to my point…

If anyone fancies grabbing a ruler and measuring the width (the widest
part of the tyre when inflated and including any knobbies sticking out
past the tyre wall) of their tyre and letting me know I’ll update my tyre
reference page at http://www.wobbling.unicyclist.com/Tyres/ If your tyre
isn’t already listed in the page I’ll try and track it down and add it in.

I think this would be a valuable resource to maintain as I’m sure lots of
folks don’t buy a perfectly good tyre at 3.0 because it won’t fit their
frame when it would actually fit fine.

Cheers, Neil

We had a couple of unicyclists stay at out house Wed. night, and they
brought a pile of unicycles (on their way to NUC). So at midnight we
started measuring tires and frames. I added this to
www.frames.unicyclist.com I measured the Arrow Prime Wide as being 2.65
inches Gazz 3.0 was 2.75 in Gazz 2.6 was 2.45 in Monty was 2.7 in

As for frames, we measured the distance between the fork legs (also
listed on frames.unicyclist.com) 24" DM ATU 2.85 in Pashley 2.66 in
Profile 2.93 in

20" Wyganowski 3.15 in

Ah, I forgot to list it, but the Kujo 2.35 was really 2.35 inches. Do they
make a 3.0? :slight_smile:
