You might want to consider a taller (larger number) aspect ratio. That 215 tire would be a bit smaller than stock, which would reduce your top speed somewhat.
A 225/70R16 would be 28+ inches diameter vs ~25 inches diameter for the 215/50. Either would fit on your 7" wide rims. Or a 215/65R16 would be 27" dia.
