No real secret. Tires are a pain to ship. You can usually save yourself some money and ship them box-less (they ship from tirerack.com boxless and they're never damaged) but then youll probably be charged a fee for an "irregularly packed" item, no matter what carrier you choose. I've gotten as low as around 25 dollars/tire depending on where I shop around but it's never cheap. I also always cross shop FedEx UPS and DHL, open up 3 browser windows, put all the info in, click "get quote" 3 times, and compare from there, going with the cheapest.
