Tyre sizes

[compo]

I have been looking at tyres for my hybrid. 700x28c. I have seen 700x28, 700c x 28 and 700 x 28c. Are they all the same or is it just variations on a theme?

Thanks.

Always best to use the ISO sizing: 700C is given as 622x width, ie 622-25. The 622 is the rim diameter for the bead of the tyre. Most cycles will be 622mm or for ATB, 559mm.

A fine machine, esp. as a three speed.
