please help: Schwinn Cross-Fit Tire size

[Joe]

Hello all,

I am a newbie and I have inherited a Schwinn Cross-Fit from the early
90's. The tires are beginning to dry-rot and I am unable to find a
good tire size to replace them. I will be riding mostly city pavement
(downtown Chicago) but a little grass and dirt, so I can't use touring
tires.

All I can find on the tire are the following numbers: "40-622" and
"700 x .950"

Does this mean anything to anyone? Any and all suggestions would be
greatly appreciated

Thanks,
Joe

Hi, Joe-the-newbie.

The .950 means nothing to me, you are probably misreading it.

A 700 x anything tire means that the diameter of the portion of the rim
that supports the bead of the tire is 622 mm, and the 40 refers to the
width of the tire. That's a pretty wide tire, but replacements are
available at any decent shop or online. Contrary to what you said,
touring tires would probably work fine. You don't need knobby tires, and
you probably don't need tread at all.

Sure you can, touring tires don't mind a little grass and dirt!

These are the size commonly known as "700c" and any bike shop will have a
large selection of them in various widths and treads.

I'd suggest something in a smooth tread, 28-35 mm for the type of riding you
describe.

I particularly like the Ritchey 32-622 (700 x 30) Tom Slick. We sell these
for $19.95 each.

The $22.95 Avocet FasGrip Duro 35 mm is also an excellent choice, similar
width despite the different markings.

This is an extremely popular size and should be available at any competent
LBS. You should ask for a 700C tire and peruse the selection. The width of
yours is 40mm. There are more choices of brand/model at 38mm which is
pretty much the same thing. 35mm are also popular and available if you
think a skinnier tire is desirable. Anything from 28mm to 43mm will fit.
Inner tubes can be either 700x38~43 or 27x1-3/8", they both fit fine.
