I run the same tire in 285/35/20 on 10" wheels in front. 275 seem more popular though. Lowered 1" so flush look no poke. 315/35/20 in rear but those are 11".For a 9" wheel 255/35 or even a 265/35 would be a better fit. For a 10" wheel 275/35 or 285/35 would be a better fit. Plenty of people run anything from a 275-305 on a 10" rim. Your set up would work but your rear tires would probably have some poke though. I cant stand poke so I'd lean towards a 255 front and 275 or 285 rear. Good luck and let's see some pics after there put on.
