Width of tires

[obxbes]

Relatively new to cycling. Iwas wondering why one would choose to ride on 23cc,25cc or 27cc tires.

Narrow tires weigh less and provide less cushion for the rim and rider.
Wider tires weigh more and provide more cushion for rim and rider. Wider tires usually have more and thicker tread; therefore they last longer. They often cost the same as their narrow counterparts of the same model.
Compatibility with rim width matters as does fit in frame/fork/brakes.

Narrow tires usually are rated at a higher pressure, and when pumped up to near maximum give less resistence. Wider tires are more suited to heavier loads, as in big riders, and fully decked out touring.

Yup. What he said. I'll even use a 23 up front and a 25 or 28 in back as the rear tire will wear out so much quicker. It also provides a slightly more cushy ride as most of a riders weight distribution will be on the rear wheel. It may look a little dorky but I gave up on cool years ago.
