Greetings Rep... Could a 26 X 1.95 tire fit on a 26 x 1.75/2.125 Rim?... Thanks

do the Math....
In a number line, 1.95 sits neatly between 1.75 and 2.125. Not linguistics.

Just about certainly. 26" standards can be confusing, but if it's written 26 x (decimal number), it's basically always referring to a bead seat diameter of 559mm, AKA "26er". So that rim and that tire should match.

More like do the linguistics. Simple number comparisons don't always work with tire sizes; we live in a confusing world where a 27" rim is bigger than a 28" rim, and a 27.5" rim is smaller than both.

The rim width will be a single number, so I'm a little bit confused by your mention of "1.75/2.125" as the width.

There's a good blog post here with a chart in it that might help:

THE RIGHT TYRE WIDTH ON THE RIGHT RIM WIDTH - Engineerstalk : Engineerstalk

Look on your rim for two numbers in the form 559-23. Your tire should have a similar set of numbers. The first number, the 559 part, needs to match for sure. The second number goes to width, and you want your tire to be reasonably wider than your rim.

What is a "26 x 1.75/2.125" rim even mean? Where did you get that term from?

I assume 26 means 26" wheel, but where did you get the "1.75/2.125" part from?

I'm going to take a shot here and say for some reason your rims have the recommended tire widths stamped on them. The 1.75-2.125 is the tire width range that will work on those rims, and if that's what it is, your 26 x 1.95 will fit fine.

OP - it should.

One of my wheels has a Weinmann rim with that designation on the sticker. Instead of giving a rim width (although it may have that too, can't remember) it lists acceptable tire widths. It tripped me up the first time I saw it, too.

+1. If the rim has an internal width of 27mm, then a tire between 40mm and 54mm wide would be recommended under the old rules of thumb.

Go here Tire Sizing Systems and go down the page until you see the chart in green and red showing which tire widths will fit your rim. The way to measure the rim width is also shown near the beginning of the page where you can read about bead seat diameter or B.S.D. as that section is labeled.

ditto on what VegasTriker recommended. Read whole thing and understand what BSD is.

Once you've got that you will always be able to pick a correct size tire for your rims. The ISO size is stamped on every tire I've ever looked at. You might have to look hard as sometimes it is the smallest lettering. Rims don't always have their BSD or inside rim width on them, but if the tire you took off fit correctly, then you can get the BSD from it. You'll have to measure the internal rim width with calipers.

For those not familiar with what he is asking, there is no need to do any math. Manufacturer is just saying that anything 1.75-2.125 is what they recommend, a range in which his 1.95 easily falls into. Here is my wheel, with the same designation:

They give the ETRHO on that label too which is 559x24 as best I can make out. ETRHO is pretty much the same as ISO. It gives the BSD as 559mm, and since this is on a rim, the 24mm wide across the inside width of the bead seat. On a tire the width part of the ISO/ETRHO would be the external width of the tire.

For me it is much simpler to think in terms of ISO/ETRHO numbers when looking for tires. My son has a 29'er. I wanted to get him some narrower slick tires for him to do a Century ride with me as he had no other bike at the time. I was told by many that a 700C tire would not fit that bike which the rim in bold had AT-650 on it.

The iso/etrho number on the rim is 622x20. So I went ahead an bought 37x622 tire which is also labeled as 28" x 1 3/8" x 1 5/8". It fits perfectly and he rode the Century on a tire more appropriate for road use and much lighter tire than the originals.

Etrto 559 ? its metric you know...

So? metric doesn't change anything. It's the number that tells if a tire and rim with fit. Much easier than trying to remember 22.008" as opposed to 24.488" which is a 622mm which 700C and 29er tires are.

559 -47 tire is also marked in inches and fractions ... avoid tires that are not marked with both.

ETRTO is a technical agreement so tire and rim manufacturers around the globe can make things fit

I've never seen a tire that has the ISO or ETRTO in inches. The number you see in inches on most tires has no firm relation to the BSD and width which is what the ISO and ETRTO describe.

Well it's larger than a 1.75 and smaller than a 2.125, so...

The picture was posted after my original comment. My point was simply that some rims already gave a manufacturers recommended tire width, there is absolutely no need to go do calculations if you were attempting to fit something within such a range on the label.
