may have said:I'm ordering some tires for a bike but some of the sizes are in fractions (1
3/4) and others are in decimal (1.75)
Is there a difference?
There sure is!
Quoted message said:The rim is 26 x 1" (outside diameter) and have been told here that it will take
a 1.75" width tire. It currently has a tire that says 26 X 1.50
A 1" wide rim (outside measure) of typical designs will easily support
anything from 1.50 to 2.00" sectional size. It is not unusual to see
tires beyond that range installed on such a rim, and it usually works
well enough for the average rider to have no problems.

Both of you....
Would I be safe in ordering:
Cheng Shin C1027 Raised Center Tire 26 x 1.95" Wire Bead BSW
http://www.amazon.com/Cheng-Shin-C1027-Raised-Center/dp/B000C15KE8/ref=sr_1_64?ie=UTF8&s=sporting-goods&qid=1212532851&sr=1-64
Safe, yes. Advisable; not so much. There's way more tread knobbiness
on there than you need, and it's probably going to buzz a bit.

Cheng Shin C215 Street Tire 26 x 1-3/4" Wire Bead BW
http://www.amazon.com/Cheng-Shin-C215-Street-Tire/dp/B000C15NOU/ref=sr_1_71?ie=UTF8&s=sporting-goods&qid=1212532851&sr=1-71
Will Not Fit! This tire is made for a different diameter of rim than
what you have. Note that in the extended information one says 559 and
the other says 571; those two numbers are the rim diameter in
millimeters. It has to match the rim diameter of your bike or the
tire will not fit. Since we already know that your bike has
decimal-size tires now, we also know that it has 559 wheels; no
question of it being anything else.

Better than the first, but not what I'd buy myself, which is this:

That's a 26 x 1.50 city slick tire which I've had good results with.
Quoted message said:Do inner tubes come in sizes like tires or is it one size fits all?
They are specific to an extent, but when you have two sizes to choose
from with close or overlapping specs, pick the one that has the larger
high-end to its range of appropriate sizes. For instance, with a
26x1.50 tire, if the choices available are 26x1.0-1.75 and
26x1.5-2.25, you are generally better off with the 26x1.5-2.25.
Remember: fractional and decimal tire sizes are DIFFERENT, they are
used on wheels that have a different diameter, and they don't
interchange AT ALL. 26x1.5 is NOT the same as 26x1 1/2. In math,
they would be; this isn't math.
One other thing: there are two types of valve used on bike tubes;
Presta and Schrader. Schrader valves are what you are used to; they
work like the valves on a car wheel. Presta valves are different;
they are skinnier, and they have a locknut on the end of the valve
core (which sticks out of the end of the valve). UInless the bike you
have is already equipped with prestas, or you like having to fiddle
with extra steps when airing up a tire, stick with Schrader-valve
tubes. Most non-bike-shop sources will generally not have
Presta-valve tubes, but Amazon's marketplace suppliers have both.

get a couple of them for the tires. I'm going to buy two tires.
Sounds like a plan.
