What is the 27x1-1/4 tire? Is that similar to a 700x38? Or is it like a 650x__? please explain for me

The bead seat diameter on a 700 is 8mm smaller than a 27 inch. 1 1/4 is 31.75 mm. Regards,Dave

ISO, the International Organization for Standardization long ago developed a universal tire sizing system that eliminates wheel & tire size confusion. But that does not stop inventive marketing A 27x1-1/4 is a 630 mm tire used on most older 10 speed bicycles in the 1980 and before. A 700x38 is a 622 mm tire that is wide, most sports styled bicycles since 1980 use a 700x23/25 tire size. &lt;--recent marketing term 29er is for wider tires fitted to 622 rims, sometimes marked with a French Size 28 A 650c Triathlon, time trial, and small road bikes is 571 mm. A 650B tire is a French size being revived - 584 mm &lt;--using long reach brakes these are are being put on hybrids & sports style bicycles that do not offer the room for tires wider than 25, nor any room for fenders. If your old tire is labeled 27x1-1/8 or 27x1-1/4 you have a 630 rim and need that size tire, Get the 1-1/8 if you are a light weight rider, or the 1-1/4 diameter if heavier, also it has more air volume for softer ride.

The impression on the tire indicates (260x85), and the tire measures about 9-3/4" in diameter. Hope that helps.

Hey Joel- The size I bought was 31.5" or so, across from the center of the wheel (tread to tread) just use a tape measure or yard stick. the tires were 7:50 X 16 this crosses with a 235 X 85 R 16-- they are darn near the same! a 255 is a little fatter/wider/lower and a 70 series is less tire, rim to tread but the wheel is 2" taller to start with so it is best to just measure it yourself as there are many sizes of tire covers. just keep going down the lists until you find your size. hope this helps. Linseed oil also helps the rubber if it sits all winter. (the tires I have is what is best in snow) Nick W.

I don't understand where people come up with things. It's a 23 mm tire that holds 150 psi. I run them at 120. Where does "comfort" or "harsh" fit in here? They handle as well as the Michelin Pro Racers I used to ride, they're cheaper, and they last 3-4 times as long.

Assuming that you mean 27" Rims. My Cycle that has this brake has 700c x23 tires, and it works great . I'm not sure if that helps you.

The size is the same. (I think these come from different vendors...check the vendor when you select the size and see if it changes) I think the main thing to look for is if the tire is foldable or not. I bought the non-folding tires. They are a little heavier, but cost less. Folding tires cost a bit more, but are more expensive. You have to really look at the weight between the tires to tell them apart. I think the 700x23c are 280 grams for non folding and 230 grams for the folding. I am a big guy, so weight isn't an issue. I'm 6'5" 225lbs and these work great. I just did a half Ironman triathlon with them and had no issues.

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!

Sorry - I don't have this tire to check, but Continential only lists 27 x 1 1/4 with ISO 630x32. The general rule for bicycle tires IS fractional sizes and decimal sizes DON'T MIX. It's a valid question - although I'm not aware of that problem with 27" size, I have definitely experienced problems with old 26" sizes even within the same inch size designations. I suspect someone that was unaware of the mismatch issues just used the decimal designation by mistake. Best to check the ISO numbers of the old tire ( that did fit ) if possible - look at the larger number, that's rim diameter. In this case you want 630-xx (for a 27" tire).

No the 1 & 3/8 is a special size for older Schwinn sized wheels it will not fit on a 27x 1 & 1/4 wheel. Alsonote that on big cycle sized tires the decimal and fractional sizes are not always the same size.

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.

The 26X1.9 refers to the 26 X 1.9 inch version. However I am sure this tire is of the mountain-bike variety. I own this tire in the 700X19mm tubular, and the aforementioned 26X1.9 inch is not in the same category, nor price range. I would call a high end bike shop and, or go to one in person, at least for a look over, as to get a genuine reference as to what you want. You would hate to be disappointed at getting a fat tire for your racing machine. Good luck, and take care....

Your looking for tire size and tube size not product code. Although the tire manufacturer does have a website. Its really useless when it comes to ordering anything. I think this bike's tire and tube size is 700x25c. As long as you get a set thats identical to what the side wall of the tire indicates its fine. Also dont buy a heavy duty inner tube. They wont fit when you place the tire over it on the rim because of the extra thickness.

I took my 700 x 38 tires off and replaced them with 700 x 28. It fits perfect !!

yes, this tire (CST Ciudad RS Kevlar Tire, 700 x 32) is the same. when you get it you will see that it is marked 700x32c (32-622) also......... BTW: this is a very nice tire..........

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.)

(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.

If you look closely the two different options for each tire size (700 x 23 and 700 x 23mm) have different prices because they are being sold by different Amazon resellers. What appears to be a part number next to one of the 26x1.75 options of 47-559 is actually just another numerical system for expressing the tire size. You were right Harvey, I really didn't answer the question well enough the first time. So my advice, choose the one with the best price and best shipping! Good luck.
