A guy from Puerto Rico and a guy from S.Arabia mentioning the difference between summer and wintertyres. LOL!
We don't know the outside/asphalt temperature in that video, only that it's partially(very) wet. And good summertyres will do a lot of good when let's say at +5 degrees Celsius. Been there done that.
Marketing strikes again
Wintertyres are best in snowy conditions, wet they will do the job but not like a good summertyre (that's why I have them on now no snow hahaha)
