Those ones outlined in red are an interesting style.
Not much to add so I crave your indulgence as I ramble.
It's interesting the differences between the narrow, taller tire and the wider, shorter tire within the range allowed "by the book." I mean, you could have a nearly 3% smaller circumference and a .7 inch lower stance by going with the 215/50R15s instead of 195/60R15s
You'd have better low end pickup with those shorter 215 tires I bet, but maybe you go to the 195s for snow tires. Interesting implications. I'm thinking this through a little myself as I consider Bridgestone Potenza RE-71RS 215/45R16s for dedicated summer tires and something like a Bridgestone Blizzak WS90 195/55R16 for a dedicated winter tire.
There are still 215/50R15 tires available, but your choices are somewhat limited, at least per Tire Rack. Vredestein and Pirelli.

Trouble is, unless someone wants to go stock, 15s are out of style. Even 16s are considered quaint by some. For my part I like a little sidewall.
