IMO, a 275/50-15 at 25.7" is too short for the car, and too wide for an 8" rim. But many people have run them.
A 7" rim in the front is too wide for a skinny look, but you could go for height instead. A 275/60-15, which is 28" tall would work. But the rim offset would have to be ideal, and the speedo would read too low.
