From what I remember, you will need to cut down a little larger size. I haven't been able to find a 4-20 either. There is a Youtube video of a guy that cut em down...

Yep this is the correct answer.

Here are some Mr Tuffy 3XL E-FatTire Liners that will fit our 20x4 fat tire bikes. All you need to do is cut them down to fit size, pretty easy.
 
So when cutting these liners down, how do you do the ends so the tube doesn't get pinched - or isn't that an issue?

Do the ends overlap each other? Do you leave a small gap between them? How is that handled?
 
I personally left a tiny less than a mm gap between them seeing as thats a null chance that a nail will get exactly in there...But you could overlap them if its a tiny amount and it wouldnt do any harm.

Since the width is already set, all you have to do is cut the length...pretty simple.

Mr. Tuffy liners normally overlap the ends by a couple of inches. If you cut them down to fit a smaller diameter tire, let the cut lie underneath the factory cut end.
