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.

The wheel is 700 x 25. You want tubes that are 700 x 25. Usually tubes will come in ranges. Most common range is 700x18-23 and 700x20-25. Both will actually fit the tire as tubes expand easily. If you do decide to use 700x18-23, go 10 less than the maximum PSI on the tires. If you go 700x20-25, you're can just fill it up to the maximum PSI.This bike does not require the valee to be a schrader valve. Presta works as well. I have prestas on mine as they are easier to work with when you need to deflate for quick changes.

I'm running 700x25, I think you could get away with a 700x30. Refer to http://www.biketiresdirect.com/tire-width-article, these rims are 14mm inside width; according to the chart in the article, you should be okay as long as your frame allows.

That's the correct number. 700x38c is the tire size. I like these tires on my Schwinn Avenue hybrid. Very nice and they have worn well.

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!

mine said 700c x 25 and my tire was 700c x 25 and the tube was much larger than 700c. Im not sure about the 25-32mm we never got that far,it was much larger than the wheel.

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

Marketing names. They are all the same. Officially it is 700c (tire size) 23mm tire width.

20 mm inside 25 mm outside This means a good tire size would be 32-47mm Of 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

Do you mean 700 23c ? If so them yes that's what I mounted on the rims I would say it would easily mount a 28 cm tire but not sure if you mean 32

Hello.The factory 255/70-17 tire is 'recommended' for wheels up to 8.5" wide. That being said, we have seen customers use their OEM tires on this wheel.Thanks,BWT

first, make sure you don't have 26 inch tires, like a mountain bike - because 700x26 is kind of an odd width. i'm sure it exists, but it's not that common. if you really do have 700c wheels, then there's a couple things you need to consider.1. is there any room in the frame for a wider tire? stick your nose down there and see how much clearance you already have.2. is there room for fenders, if you need them? this may not matter.if it fits in the frame, there's no reason you can't go wider. i've done it. if you have calipers or v-brakes, make sure you open them correctly to allow the installation of the tire. good luck. this is a good tire, in my opinion, for the money. first, make sure you don't have 26 inch tires, like a mountain bike - because 700x26 is kind of an odd width. i'm sure it exists, but it's not that common. if you really do have 700c wheels, then there's a couple things you need to consider.1. is there any room in the frame for a wider tire? stick your nose down there and see how much clearance you already have.2. is there room for fenders, if you need them? this may not matter.if it fits in the frame, there's no reason you can't go wider. i've done it. if you have calipers or v-brakes, make sure you open them... » Read More first, make sure you don't have 26 inch tires, like a mountain bike - because 700x26 is kind of an odd width. i'm sure it exists, but it's not that common. if you really do have 700c wheels, then there's a couple things you need to consider.1. is there any room in the frame for a wider tire? stick your nose down there and see how much clearance you already have.2. is there room for fenders, if you need them? this may not matter.if it fits in the frame, there's no reason you can't go wider. i've done it. if you have calipers or v-brakes, make sure you open them correctly to allow the installation of the tire. good luck. this is a good tire, in my opinion, for the money. « Show Less

The furst numbers before the size must be the model no. The 700 refers to the metric diameter and the 38 refers to the tire width. These are a wider than average tire but not as wide as those balloon tires you see on cruisers. I really like these tires for their width. Good for touring or even some trails. They are kevlar lined which will help against flats. So if 700 38 is the size you need these will work just fine.

Most would probably say weight. I ride with a 25 on the rear and 23 on front. I would next time just do a 25 or 23 on both. If your a hard core racer go smaller. If your like me and just ride and commute for fun, 25 is good. A 25 provides a little more contact on turns.

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.

usually a 700x32 doesn't fit on the same rim as a 700x23. if it does fit you will need a new tube.
