Welcome to the forum.Hi all,
I have my first bike for about half a year, it is V Strom 650 with tires from 2017.
It's not unusual for tyres to get a bit shiny, particularly in winter whenRecently some glossy coating develeped on a tire surface (please see the picture).
It doesn't seem safe, though I didn't find anything like this on the internet.
temperatures are low and you aren't using the full width of the tyre.
Take them for a spin on a warm dry day and they should scrub in again.
It looks like you have plenty of tread left. The minimum limit here is 1mm and mostWhat is this and how to get rid of it, may be it is time to change tires?
tyres have wear indicators at 1mm. I believe there is a more stringent limit in Germany,
