We should stick to the topic.
I will not favor buying smuggled tires.
I will however favor Mr n4nomi, if anyone has imported good tires and paid the import duty on it he can sell it at any price he wants.
It is not our duty to investigate all consumer products and curb smuggling or maintain the balance of payment.
Continental are premium tires and they have a much higher brand image and reputation then YOKOhama, Yokohama's have some outstanding tires like S drive, Db V550, db spec E and Advan sport but their mainstream tires are not very talented.
I will rate Continentals even higher then Michelin and Pirelli and equal to Bridgestones for their quality control and tread design.
