What do the numbers on the mantle mean? I've just removed the mantle of my back tire as it has a hole (probably cut by glass). I wanted to look for a new one, but then I realized that I'm not even certain which size it is.

So I looked on the old mantle and found more numbers than I thought:

vtech EAGLE 42-622 700x42C &lt;MDS&gt; (Max durability System)



700 - 42 (42-622)


NL F024   17


I guess vtech EAGLE is the brand / model name, MDS is just some advertisment. But what do the numbers mean?

(Side question: Living in Germany and biking mainly / only in the city, where and for which mantle should I look?)
I think I just found the answer from https://commons.wikimedia.org/wiki/File:Reifengr%C3%B6%C3%9Fen-beim-Fahrrad.png:



So:


The diameter at the outer is 700mm,
it is 42mm wide at the outer,
622mm is the inner diameter
