For some reason I couldn't find any of the previous threads on this so I'll just ask here. We have 205/50R15 and 225/50R15 on our Stang right now and need new tires. Since the sizes are so awkward we're going with all new sizes. I'm assuming we have 15x6 front and 15x7 rear rims. What's a good tire size to go with these and can you guys recommend any good rain tires? Thanks for any help.
