I have read just about everything I can find on spares for the car so I do apologize if this has been answered. I bought a spare kit from ebay that states it fits the LT and premier. The doughnut, jack etc showed up and all looks great, but the spare is a 16 inch and the circumference is clearly less than my premier wheels/tires. The seller calamine there is no 17 inch doughnut? Am I missing something or will the 16 inch work on the premier?
