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.

you need tires that are 26x2.125 if you have a 26 inch bike.most tubes will say on box.26x 1.75 to 2.125 put a little air in tube,then put in tire to,install easy..if its late 50s could be 26x1.75 make sure of 26-25 size wheel make sure of your size put wheel next to other size wheel on a other bike keep riding!!

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

Judging by your tire size, I would go with the 28 inch.Sorry for the delay in answering, but I was out of town until today. Good Luck.

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

(DISCLAIMER: I am no tire expert) I don't believe the tire size (650mm, as measured by you) directly correlates to the 650c (or 700c) designation. If your rim says 700c, then get the 700 x 23. BTW, the size is also imprinted on the tire sidewall.

Yes, just order the 700 x 28 size. Remember that tire dimensions are 700c (diameter of the tire) and 28mm (width). I.e. the "c" goes with the former dimension, not the latter.

Tire size is 26 x 1.95, max psi is 65 but I ride mine @ between 50 and 55 psi.

i think yes.i am using 29in tire size bike.700c is equivalent to 622mm or 24.5in.correct me if i'm wrong.

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

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.

In my experience the size of these tends to run large. If it gives you two options for your tire, go with the smaller one.

I googled this and based on the following, it should fit. 700 is the size of the wheel and tire which the tube is intended to fit. In this case, 700 means 700c, or ISO diameter 622mm rims. If you are unfamiliar with tire sizes, take a look here.28/32 designates the min/max range of width of the tire which the tube is intended to fit, in mm. So in your case, your tubes are designed to fit tires of width 28mm (minimum) to 32mm (maximum). This range should correspond to the width of your rim as well.

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

Depends on the tube you have and can be hard to read the lprinted info once they've been in a tire for a while. I usually switch out to bigger tubes for 32 mm tires when changing from my 23s

When you say tube, the tube size depends on the tire size. So, a 700x23 tire would take what you seem to be saying is a 20-25 tube. A 700x25 tire would require, obviously, the larger size tube. Having ridden both, my preference is definitely the "skinnier" tire--700x23. Might give up a little in comfort, but you will gain less rolling resistance.
