    700x23 VS 700x23c tire question

    what's the difference, if any, between a tire listed as 700x23c and 700x23 and does is matter which one I get if my bike now has 700x23c's?

    Thanks!

    all tires of the same size are not = in size. every maker is a little different.

    The letter(in this case "c") was for different spec rims. I don't think you can even find a non "c'" tire any more(Except the 650 size, ther is still a 650b)

    700C is the rim size. 23mm is a tire width common on 700C rims. The common practice of placing the 'C' after the tire width is a silly and archaic habit in the bike industry (as is referring to obsolete French sizing nomenclature, but that's another rant).

    If you want the long answer, as always, go to http://sheldonbrown.com/tire_sizing.html

    I have to disagree.

    A 700c tire has a larger bead diameter than a 700d tire. So why wouldn't you put the letter on the tire size?

    ...which is why you should scrap all those archaic, misleading numbers and stick to the ETRTO numbers. 23x622 is pretty clear.

    I hope the OP is not confused by the silly back and forth caused by their post. Both tires are the same size and are completely interchangeable.

    I thought 700a, b, and d had gone extinct at this point. Is anyone still using them?

    Actually we had a 700d bike come through the shop this year. If I remember right we couldn't find tires for it so we converted it to 26" wheels.

    Sorry. I wasn't clear. I don't suggest REmoving the C, I suggest moving the C from the commonly used position after the tire width to after the 700. So instead of referring to 700x23C, one would refer to 700Cx23mm.

    Even better, dump the French designations altogether.

    If only it was as easy as that. One of the guys took the bike in for new tires and a tune up, quoted the customer a price and everybody's happy, right? WRONG! Retro Grouch bops into the shop, takes one look at the bike and says "That's going to be a problem." Now somebody has to call the customer and explain why his tune up is going cost $100.00 more than we had estimated.
