What is a column in this context? This is all so confusing. I just want to know what these weird sizes like my bike tire (700x42c) means in terms of width. Apparently it seems I don't need to be worried about the first number (700) as that is the diameter of the tire which is available with a variety of widths - is this correct? So what 700 means doesn't matter. I just need a tire that has 700x(Insert numbers here)C. Whatever the heck that C at the end means I don't know.

I read -

Puncture Proof Tyres Tip​

If you can fit them on your bike the 25mm or 28mm puncture proof tyres will provide greater comfort and a smaller chance of a pinch puncture.

The second figure is the width, ignore the C

The column in the table with the heading French in the Schwalbe link.
for the 3rd time, 42c = 42mm for your tyres
ignore the bit about 25 & 28mm tyres, that’s for road bikes which traditionally came with 23mm Tyres, not fat tyres hybrids like yours

Is English perhaps not your first language? If so, it may just be easier to do a Google search in your mother tongue?

WTH. It says the same thing Halfords website says. 700x(INSERT NUMBERS HERE) C.

There is NO mention of tire width in any of the columns. That should be stated in Millimeters. MM.

What tyre? It’s the French column…c = mm

You worded this very poorly. I think you meant:
''What tyre are you looking to buy? In that link he provided you with information on tires by Schwalbe, the width of the tire is listed under the column ''French''. The C at the end in fact means Millimeters''.

If that’s clearer, fine. I am posting quickly while trying to work :biggrin:
In post #53, you asked what is 42c, I said it’s 42mm which seems pretty clear :rolleyes:

Ok, you aren’t getting that in tyre speak, C is equivalent to mm as @fossyant said

RIGHT here we go. And THIS information I could not find on Google from my research. It is incredibly stupid for them to use all these different systems like inches and millimeters and then also add a stupid random letter at the end of the measurement ''C''. WTH is up with that?! Talk about making it incredibly confusing for consumers.

Cycling has been around for eons, some terms are historical, there’s no need to overthink, we’ve all explained it several times. For your bike, the 700 bit is actually much more important when buying tyres and getting a width (be it labelled in c or mm) in the general range of your current. With that bike, you won’t have clearance or fitting issues with any tyre width from 35-47c (or mm).
You've had one puncture in bad weather (possibly your tyre pressure was too low too), there’s no need to rush out and get new tyres as @fossyant said already.

That Schwalbe thing is most ridiculous and confusing document, it’s aimed at retailers and mechanics more, just bin it!

The document seems very useful. Reading it right now.
No one explained that C is the same as millimeter, nor is there any explanation WHY. It was not explained in a clear way with words.

I got myself confused too when I started a few years ago. I recall it's basically a mis-stated standard, should be 700Cx35, the C refers to the wheel size not the tyre. People, myself included now, often state it as 700x35C. Don't worry about it.

I have been looking at Halfords site since June of this year and this is the first time there has been an offer on accessories and parts for cycling.
Why can't I find 42c tires? Seems there is only 38c max size?

42 are mainly aimed at mountain bikes, rather than road bikes or hybrids. But you can get 42mm tyres, just not from Halfords.

oh, why does my Hybrid come with 42mm as standard? What tire size should I replace with IF I change the tires? Is it worth buying sets of tires for different scenarios, such as winter tires, tires better suited to gravel, tires better suited to asphalt etc?

Am I right in saying that only ''700'' will fit my wheels? That no other size will?

Where can I find out what 42C is in mm? I cannot find tire width info for the French measurement system (which is apparently what this is (700x42c) anywhere.

You have already been told, the 42 is mm. It will actually usually be expressed as 700cx42, not 700x42c, but that doesn't really matter.

The 700 is the diameter(ish) of the wheel in mm, the 2nd number is the nominal width of the inflated tyre when on a rim of the ideal width for that width of tyre. The actuall width can be out by several mm, particularly if you put them on a rim which isn't the optimal size.
