700-c vs 27 1 1/4 tyre
#1
which one has less rolling resistance?

And can they be used on each others rim?

found this on sheldon site
630 mm 27 x anything
622 mm 700 C, 28 x (two fractions), 29 inch
(28 x 1 1/2 F.13 Canada)

what is the wideness of 700c tyre?
thanks!

700c does not have anything to do with width of tire. It has to do with the size of the wheel.

What type of bike are you putting this on; road or hybrid? A bit more information would help us help you better. Also, what type of riding are you going to be doing with it?

To boot there are other factors of the tire itself like tread, etc. to consider!
Good maintenance to your Bike, can make it like the wheels are, true and smooth!

NO! 27" and 700c cannot be crossmatched, these figures refer to the diameter of the wheel under the English (and US) in inches, and the continental system in millimeters, there is not much difference, but enough prevent cross use.
See this for more info:

Rolling resistance will be the same for either size if the other parameters are the same, ie. width of tyre (1", 1 1/4", or 25mm. 28mm. in the metric system), tread pattern, pressure, etc.

As a general rule, larger wheels have a lower rolling resistance than smaller ones (all other things being equal). This is primarily due to their better ability to roll over a bump on the surface rather than being deflected off their forward path. Because they have a larger contact patch, larger wheels also force the tire to deform less which reduces energy loss. There's also benefits from having a larger wheel that rotates more slowly for a given speed.

However, larger wheels tend to be heavier which means they take more energy to accelerate. Their advantages come in at steady speeds on flat ground.

Of course, when comparing two sizes so close together as 27 and 700, the difference between tread, tire construction, and pressure will completely overwhelm the wheel size effects.

But to answer the original question, no, you can't mix 27 & 700 tires/wheels.
