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.

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

The sidewall of the tire lists the size as 700x38C. I measured with a tape measure, and from side to side they measure approx. 1.5 inches (3.8cm). These tires have worked well so far on paved surfaces (asphalt and concrete) and hard-packed surfaces (cinder and dirt). I haven't taken the bike off-roading, and probably wouldn't recommend it due to the narrow tire width and shallow tread depth; however, for paved/packed-surface bike trails and street/sidewalk riding, they're perfect. I hope this helps. Good luck.

I went and looked at the tire/rim and it shows tire 40-559, 26 x 1.5 and rim 559 x 20 and PSI 40 to 65. This may be more than you want to know but just thought I would put what the tire here showed.

I think it comes in different sizes. 26" is usually a fatter tire. I think this is mostly for the 700c. I purchased the 700c for 25mm tires.

Your question is pretty vague. I'll try my best to help! This will be a wider tread than a 700x25 or 700x23. This will give you a bit more rubber between the road. Many newer road frames may not have clearance to support the 700x32, or it'll likely be a tight fit. Rolling resistance is greater than a slick tire, but I can also tell you the extra tread provides great all terrain travel. I use these on hard pack gravel with no issues, and no flats to date with 1K miles on them now.

Hi George, It's really personal preference but I would stay with the 27 X 1-1/4. When running a wider tire than recommended it tends to move on the rim when cornering . On low pressure applications this isn't a problem because the tire flexes but at high pressure applications the tire can't flex and can break the bead causing a blowout or flat.

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..........

The 1.5 size offered in this tire is fairly narrow, too small for some wider rims on beach cruisers (1.75-2.125); 1.75 is narrower than a typical mountain bike tire (1.9-2.0). It is odd that a tire would have two sizes 1.5 and 1.95 at the same time; usually that is reserved for other components (tubes, liners, rims) that fit a range of "different" tires. For example, I've seen a "Presta" Mountain Bike Tire Tube listed on eBay sized at 26x1.5/26x1.95, but those are tubes, not tires. Hope this helps.

Unfortunately 700c is not compatible with 27x1-1/4. 700c is roughly equivalent to a 29in rim. You will either need to purchase a wheel that is sized for a 700x38c tire, or purchase a new tire that will fit a 27x1-1/4in wheel.

The metric size of this tire is 49.53mm x 660.4mm . Not sure why you would want to reference this way ? Not international standard for a tire measurement of this size .

These tires are a "hybrid" of sorts. The sidewall of the tires reads (40-622) 700X38C. The width is approx 1 1/8"; my son's mountain bike tires measure 2 1/4"... a road bike tire is approx 7/8". The tread pattern is more of a v-tread design with a tread depth of about 1/16"; a mountain bike tire is knobby with a depth of 1/4"... a road bike is a straight tread with a depth of 1/32" or less. These tires are suitable for surfaces which are paved, packed cinder/dirt or low-cut grass. I wouldn't consider doing any serious "off-roading" with these tires due to their relatively narrow width and shallow tread depth. I took a couple of pictures; but, I can't upload them in this forum. I hope this helps.

Tire size (apart from brakes) is also different according to the description. This one uses 700x25c and the other uses 700x28c

My understanding is that these are ERTRO 584 mm tires. ERTRO is the European Tyre and Rim Technical Oragnization - seriously, not making this up. Anyway, the 584 mm corresponds to a 650b tire and should fit 27.5" rims. Whoever listed these tires could have done a better job. Checking the Continental website provides some help.

Hi K,I would say the tube is too large. I tried to fit it into a 700 X28 and had a overlap of at least an inch, making it impossible to fit into the tire. Of course I was many miles from the nearest bike shop, fortunately I had one regular 700 25 to 32 I could put in. The other part of this mis adventure was Carolina Cycles refused to honor the fact that they sold me two tubes that were basically worthless. Do not do business with them.

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.

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.
