rear 18x9 wheels

so im thinkin about gettin some 18x9 deep dish bullitt wheels for my stang but had some questions for those who may have them....seeing as how ill have the rear tires wider than the front tires that i will be leaving at the stock size and wont be able to rotate from them i was curious as to how long the average tire would last and also if anyone with this set up noticed any differences in their steering or overall smoothness of the ride with the lack of tire rotations
