I've only made one pair of tyre socks but I just notice a stage I think EVERYONE misses out

Have you noticed the the slide left/right when your using them, that because they are loose. It doesn't matter if you pull up your sock before fixing them on they some how work loose

What have you all forget !?
When rubber gets warm it stretches !

If you cut sock to lenght you as normal but the warm it with a hair dryer the rubber will stretch a bit, when it cools it should be a very tight fit !
I've not tried it yet but sound logical to me !?
