Schwalbe Weatherman

Are these tyres suitable for a Vespa PX? I assume that „TL“ stands for tubeless & I know the Vespa’s rims require tube type tyres, you can put inner tubes in a tubeless tyre can’t you?

You can use any tubeless tyre with a tube. provided the size itself fits obviously. There is an advantage gained by using a tubeless tyre with a tube. A tl tyre is structurely stiffer. Therefore it stands to reason that by adding a tube you r adding an extra layer of rubber under pressure. This practice is not new and employed racing. Carry on and enjoy.
