If you're talking about having someone ship you tires to Italy you're in for a rude awakening. No private seller will be able to ship cheaper than a website company international. You didn't say where they'd need to be shipped to, so I can only take your location from your avatar and determine it's Italy.
I am in the military which it would be shipped FPO meaning it is just like shipping to lower 48. If you don't have tires to sell then go on about your way. Let me deal with the person that actually has tires to sell and how we can arrange shipping.
