I've used this site with success to find 'maximum' tire/wheel sizes. As you'll see, they have guaranty sizing that will fit. Just start with "car" on left and follow prompts. You can force wheel size, tire size, etc and it will let you know if it fits. I did see a 17X9 with 5.3" BS for the rear....Direct Fit, And a 17X10 with 6.1" BS with a 275-40
