Hi guys, it’s winter tire time again and with the friendly tyre dealers the Mopp is raging.Since I can’t reach anyone for days now my question: I have winter tires, believe with comfort filling, although I don’t have green caps.Can I fill them with normal air.They are 3 years old and the air pressure looks a little bit low at the front.Did they buy them at Reifen.com. Thanks for everyone who answers, Sharan2001
