Looking into local, Serbian bike forums, I found out that many people in Serbia have had similar problems with Schwalbes. This seems to be Serbian (distributor) specific problem.
Is there a difference in production quality, or can wrong (or too long) storage ruin tires so that they fail this soon?
Use my bike as the main means of transport and was hoping not to worry about tires for a year at least after purchasing rather expensive Marathons. Distributor is some 100 km away from my town, so even sending tires back and getting new ones is a significant expense. Very angry and disappointed.
P.S. Always inflated to recommended 5.5 bar pressure. Total weight of bike, luggage and myself is under 110 kgs, so one tyre couldn't have been overloaded. 90% road riding.
I was just planing to order studded winter tires as well, but now I'm not trusting and might just go for DIY on some older and a lot cheaper tyres.
In Sweden, early failures of the SMW are quite well known. The studs wear through the casing to chafe on the inner tubes. Some, incl me, have had good luck with getting them replaced on warranty.
Suomityres/Nokian tend to last far longer.
DIY studded tires can be kinda-sorta OK for all-ice/hardpack riding, but are really difficult to get to last for urban/mixed surface riding.
I've tried it, and am not planning to do it again.
Don't think storage as such is to blame.
Unless storage conditions have been absolutely horrible.
There's a regularly returning story about some pro racer/team having several seasons worth of (tubular) tires stored in a cellar somewhere.
