Pretty basic question here but i am having trouble finding the answer by searching. right now I have 700x23 tires on my giant TCR2 carbon road bike. I am about to pick up a new set of wheels... is this the only size tire that will fit on this bike? If not, what are the advantages to going with say the 700x25?
If I were to go with the 700x25... would it require a diffent size tube?
thanks,
Mike

The widest size is limitted by the clearance at the brakes. 25mm should fit. You can use the same tube size.
Narrower tyres are lighter, more aerodynamic and can accept higher pressure for speed. Wider ones are more comfortable for long rides and rougher surfaces.

Thanks for the reply. In my situation (being a heavy rider) would a larger tire size be easier on my wheels? in other words, will they help to protect the rims from going out of round or geting damaged?

Larger tires can use (maybe must use) lower pressure without suffering from pinch flats so are more comfortable. The greater cushioning that provides more comfort for you also reduces the shock loads on the rims. All you need is the fork and brake clearance to fit them.
Tubes fit a range of tire widths so a tube that fits a 23 will also fit a 25.
BTW. the size marked on tires is not always accurate and a tire marked 700x25 may be no wider than another brand marked 700x23. Truth-in-Advertising isn't universal among tire makers. Take a caliper to your dealer.
