The SP3000 you're talking about, I'd imagine they're a 235/45R17 tyre, the Falcon XR6 one. The Falcon 17" SP3000 (part number 9137028) is a great tyre, but only rated at 93W. The Mondeo has a load rating of 97W I believe. So the Falcon tyre is not legal on the Mondeo - maybe you need to inform your Dealer of this! It will fit but is against ADR's on the placard on the car.
They should be able to provide a Goodyear Excellence that's correctly load rated and only about $20 dearer I think per corner, but they may even be able to match it. Part number 4083187. It's OE fitment also, so you know it's made for the car.
Just my 2c anyway
