I used to have 17x10. Just a note: there really isn't any tire that works for 17x10 or Im sure someone would say there are, but really the diameter is to small and load rating is to low and there are few choices. If I remember right - That 275 50 17 size you wrote fits a 9 inch rim. I was looking to go with that size tire but the tire specs didn't recommend 10" wide.
At shows I see quite often the year one 17" magnums with the nitto 275 50 17 tire. Im assuming the rear rims are the 9" ones. Combo looks good because the diameter is correct.
I used to have 315 35 17 rear, 245 40 17 front. I didn't like the diameter and the ride was very rough. I switched to 15" rallye's.
