The 25s roll nice, but seem to fit wide. What width tube is better; 20/25's or 25/32's?

The narrow tire is best for speed, not comfort, the wider tire covers more ground is more comfortable

Not sure what you mean by 20/25 or 25/32. but I guess that is determined on your riding terrain and what is more comfortable for you.

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.

I have 2 - 24's with a 28 in the middle. Looks good...I thought it looked better than 3 - 24's

The 26x2.10 would definetlty look alot skinnier than what your original tires on your bikel ook like now. I know because theses Kendas are the same size as the tire on my bike and they look thinner. They are great tires all around but I would reccoment that you try to find a bigger tire for your bike.

I use a 26 x 1.95 to 2.25 generic tubes with no issue. Larger tubes are not nessasary and heavier.

you need tires that are 26x2.i25 if you have a 26 inch bike.most tubes today will say on box.26x 1.75 to 2.125put a little air in tube,then put tube in tire to,install easy..if its late 50s could be 26x 1.75 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!!

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 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.

If you are planning to loose a little weight, get the 32. If not get the 34's.

the 26 is the important part so you should be good. I currently run a 23 millimeter wide tire on a 23 millimeter wide rim so the width is fine too. just don't go any narrower.

Either will work but the 31 will be a tighter fit. May look better also. My 32 is slightly big. Not bad looking though just not that drum tight look.

No you can't use them they are wider and will not fit, I will recommend this tubes [Avenir Regular Schrader Valve MTB Tube (26 x 1.50-1.75)] or any other brand of your preference in this size.

Mine are on 32", but unless you have *really* wide shoulders, 24" should be fine. If you think about it, you basically want them to be shoulder width apart

23's are more narrow and faster. Depends on the kind of riding. They are a heavier tyre because of the layers of threads and designed to take a few more rocks and stickers. More difficult to get on and if you flat. If it's endurance you ride, get the 25's. A bit smoother.

No, you cannot use a 26 inch tube on a 27.5 inch wheel. The tube can expand slightly beyond it's ideal inflation size (say, to 2.2 instead of 1.95), but it cannot grow in diameter.

Perfect tube for 700c x 23 tire. I've used them in both 23 and 25mm tires and have zero complaints.

From what I've read, the Conti GP 4-Seasons only come in three sizes - 23, 25 & 28mm. The 700x28's are what I bought to replace my old Vittoria 700X32's. The 700x28 is a significantly narrower tire (which is what I wanted) and they actually measure closer to 26mm. The benefit is a significantly faster-rolling tire than any 32-35mm tire (and most other 28's, too!). The negative is a harsher ride, especially compared to big, cushy 35mm's. I've had a few flats with them, so they're not as 'bulletproof' as they're made out to be, but all-in-all, they're great tires!

Hi Hungryman, others may correct me, but I've rode both and while the skinnier of the two *may* a wee bit faster I'd opt for the 700X25 for the greater handling and comfort. In fact, my evolution of being an enthusiast rider for 10+ years has led me to choose nothing skinnier than 700X28 tires -- on wheels big enough to accept them, of course. Forgive me pointing out the obvious, but the right tire for you also depends largely on your size, your bike, your level of experience and your kind of riding (commuting, going for speed or going for distance, pavement, gravel, etc.)
