I went through the same problem last year, tire's are available but delivery is a problem. I shoped localy as the $ was low and with delivery and customs costs the price was about the same as tirerack. I got mine from the dealership at the lowest price,but they could not install so it was sub-let to Cal-Tire, when the smoke setteled it was close to 2 grand,and damaged rims

I got Michelin A/S,they feel good and given our weather conditions I feel safe. Take photo's of you rims before you take your car in to replace the rubber and show them to to tire people before they install, as it may save you some grief
