BF Goodrich KDW's

[No Rice]

I purchased a set of motorsports 18x9.5 and 19x11. The local tire store ordered me a set of the KDW's in 265/40/18 and 295/35/19. Well the fronts came with what they call a "traditional tread" and the rears a "new tread". They are competely different looking, but the same tire. If I go down to the sizes listed below the new tread design is available. Will there being any issues running any of these tires? 255/40/18 - 26" tall 255/45/18 - 27" tall 285/40/18 - 27" tall My rear tire is a 295/35/19 27" tall.
