The 700c means it's a 700 size and the C means clincher which is what most bike rims are. The senocd number 18, 23 or 25 is the width of the tire in mm.Tubes will fit a small range of tire sizes, that is why they are marked 18-25 or 23-25.You want to look at the size of the tire, it will be molded on the sidewall and you want a tube that will cover that size.Another thing to consider is the valve stem type and length. Shrader valves are what you have on a car tire and Presta valves (smaller) are usually found on road bike wheels. You want to measure the length of the stem in mm to get the right one. Some bike rims are the deep V type and need the longer stem for that reason.

I know, it's one of life's big problems. Then you've got the nmtighare of tyre matching on top of all that. Bigger/heavier tread on the rear? I've got a pair of wheels on a touring and shopping bike with 36 spokes and a 32mm tyre on a wide rim on the rear, and a narrower rim on 32 spokes on the front with a 28mm tyre. Even the spokes are thicker on the rear. The hubs are the same, and both rims are mavic as near as I could get them. I count it as a pair. I made them like this because I only use rear panniers on this bike, and sometimes need to put a lot of weight in there, plus most of my 13 stone. No spoke breakages so far (about 15 years and counting).
