Hi all,
I have my first bike for about half a year, it is V Strom 650 with tires from 2017.
Recently 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.

What is this and how to get rid of it, may be it is time to change tires?

Welcome to the forum.

It's not unusual for tyres to get a bit shiny, particularly in winter when
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 most
tyres have wear indicators at 1mm. I believe there is a more stringent limit in Germany,
possibly 1.6mm.

I've seen that on older tires, it wont hurt anything and will wear off quickly if you lean enough to ride on that part of the tire. I'm not sure if the tires just naturally get like that or if they pick up something from the surface but in my opinion it's not something to worry about, I've never noticed any effects on the ride. I'm sure you could scuff it off with some scotchbrite when your washing the bike if it makes you feel better but I wouldn't bother. You could go ride on a gravel road too, that should scuff it right off. I'd say to check the tires date but you said it's a 2017 tire, mid life, not a problem. I see no cracks or defects in the part of the tire I can see, and it looks like you still have plenty of tread.

Go ride!

Thank you all.

I'll follow your advice and carefully scrub them in, because despite that tyres seem in a good condition.
BTW, I heard about scrubbing in tyres with a sandpaper. What do you think? Silly or may take place?

Just make sure it's properly inflated and ride it. ?

You could do that.
Some people do so you can't see that they don't do very much lean angle in corners.
It won't hurt anything but I always just use the pavement. :wink2:

You might want to see if there is a date code. Tires older than about 6 years can get a hard surface like that, and won't grip well at all. Tires made for the US have a DOT code, which should be 12 characters; the last four are the week and year it was made (wwyy). Just because they were mounted in 2017 doesn't mean they were new when installed.

They were fabricated in 2017 according to the DOT code.

I was wondering about the age of them too WintrSol.

At first glance that date looked like 1917 making very old.:devil: :grin: :wink2:

The first number 19 is for the week. They were made the 19th week of 2017.

 

[mike721]

Those tires do look old for 2017 tires.
You better start riding a lot and wear them out before they expire.. funny I never seem to have that problem

 

[Porky]

Try riding around corners in a brisk manner instead of riding in a straight line:grin::grin::grin::grin:

Sam:wink2:

 

[hogcowboy]

Oh that was almost nasty, but funny.:grin:

 

[Unkle Krusty]

Wot everyone above has said. It looks like they have been sitting a while. A file works better than sandpaper, but riding around corners is best IMA. Start slow, which is suggested for new tyres, and cold tyres.
Suzuki 650 is a sweet bike. I had a 003 SV650
