My tire size is 700x25cc should I get the 20-25 or 25-32cc?

Here is the long answer that should tell you everything you need to know about tubes and tires. First off, let's decode some of the numbers. 700C or 29" are both the rim size ISO 622 (that is 622mm in diameter where the bead of the tire seats on the rim). When you're looking at road tires, they're more likely to say 700C (from an old French system of naming tire/rim sizes) and when you're looking at mountain tires, they're more likely to say 29". Occasionally, some European tires, especially Continental, will try to confuse the matter by calling them 28" - but look fir the 622 to be sure of the size. 23/25 or 18-23 on a tube indicate a range of tire widths with which the tube is compatible. Since an 18mm wide tire has a much smaller cross section than a 25mm tire (just imagine those as the diameter of a circle), a tube designed to fit a 25mm tire can be much too big for an 18mm tire. In that case you'd risk getting the tube folded on iteself or pinched under the tire's bead - both of which can cause a flat. So, when selecting a tube, you should get the narrowest range that will fit. If you had a 23mm wide tire, 18/23 would be a better choice than 23/25, though both will be better than a 28/32, for example. The 48 or 42 mm length listed below is the length of the presta stem. Different manufacturers measure stems differently, so it's hard to get an accurate comparison, but a 32 will be shorter than a 42 will be shorter than a 60 and so on. You just need 12-15mm of stem to stick beyond the rim so you can get a pump onto it, though, for some people, a little extra length isn't a bother. If you've got a deep rim, you'll need a longer valve stem. But if the 48mm stick through with plenty of extra, a 42 is a safe choice. ORDER ROAD RACE TUBE. Thus is your present tire is a 25, I would get the 20-25 tube, less chance of the tube folding over or pinching it because it is too big. Hope all of this information is useful in the future.

Hello Vince, to be honest with you either tube will work, but I would personally go with a smaller tube because they are just easier to install on the fly...

Depends on tire or clearance on bike. Being honest with you, one of the stems in the tubes was messed up, would not mail order again....sorry.

I use Conti 4000S 700 x 25 tires and use a Conti Race 28 tube. No flats in 3200 miles.

I think I would get the smaller tube because it will be easier to change. Just a thought.

Presta Valve. Also do note: I'm using 700x28 tires and they are snug. Sheldon Brown chart shows a 28 as the smallest possible but I think you could get away with a 25.

20 mm inside25 mm outsideThis means a good tire size would be 32-47mmOf course, you could theoretically go as low as 20mm, but that could slip off. I have gone as low as 23mm, but quickly changed once I had a wider tire.Source: http://sheldonbrown.com/tire-sizing.html

For me, 25th provides a better ride. I also inflate them to a lower psi than what is recommended. I run the rear tire at 90 psi and the front at 90psi. I think that set up provides me a better ride especially on roads that have been chip sealed. Mike

Yes they are 25mm. Much better ride and handling than 23mm. Really good tire

The tire size is 700 x 38 so you would need a tube that is the same size. You only stated 700c as the tube size , that is an incomplete size number, the 38 in the tire size is it's width so get a tube that is that size also (700 x 38).

No difference. 700-28 mm refers to size of tire. 700 mm is roughly 28 in (diameter) and 28 mm is the thickness

The 26 is fine but the 2.5 might be too big. We have 2.0 tires and they are a tight fit.

Any 700c tire will fit. Only thing to watch out for is frame/fork clearance.

I use the 25mm for a more supple ride and according to the latest research a wider tire (within limits) has less rolling resistance. The weight isn't as much a factor for me and I run Mr. Tuffy ultra-light tire liners in these for added protection because flats just ruin a good ride.

I purchased a pair of 26" tires. That is what was specified and that is what I received. You should have no problem.

I mounted the fenders on a bike with 26 inch by 2 inch tires, and they fit perfect! If the 700c is the diameter of the tire, those fenders are made of plastic, and will stretch quiet a bit. I don't see any problem.

i'm not 100% sure..but I had a700x38 on mine before I went to this 700x40 and when I bought my bike it had a 700x42 on it. I wanted a little liter tire is why I went with the 38 and now 40..it also said on the tire ad that could go up to a 700x 42

The 23s are thinner, lighter (because they are thinner), and a little faster. 25s are 2mm greater in diameter, so they are a little heavier and better on rough roads. I have the 25s for training and 23s for racing. These are great tires if you don't like flats. Probably not the fastest tire around, but for me they are fine.

the recommended tire pressure is printed on the side of the tire. My 700 x 25 has a high pressure rating of 103 psi. The 700 x 23 is probably a little higher, but once again look at the tire!

You can use 27x1; 27x1 1/8; and 27x1 1/4. If your question is really asking about 700c tires the answer is no. They won't fit a 27 inch rim.

the tires i replaced on my john D. 130 were 20x10.0-8.00. best u ask a tire guy.
