I got this from the Costco website:
 
"Installation of Less Than a Full Set of  Tires
It is always recommended to replace tires in complete sets. When  purchasing 
less than four tires, the new tires will be installed on the rear of  your 
vehicle regardless of the drive axle. This does not apply to Dual Wheel  vehicles 
or vehicles with different size tires on the front and rear of the  vehicle. 
" (from costco.com   reprinted without permission  local  laws apply   your 
mileage may vary    actual mileage  will probably be less ;)
 
 
And on the subject of what tires are correct for your car, it says the  final 
decision is that ofthe tire manager at your local Costco:
 
"All tires, both new and those remaining on the vehicle, must meet all  
manufacturers’ safety standards and specifications. The final decision to  install 
a tire on a vehicle will be made by the Costco Tire center manager or  
supervisor."
