Using wrong hole pattern is a very bad idea. Especially with an alloy rim. You are asking for a failure.

I don't know from experience but I imagine the 225/60s will fit. I run 225/50s on my Miata with a 6" rim. At full lock they rub the sway bar.

For my street tires on the benzo I always use Michelin. I have tried other brands but always come back to michelin. I am running hydroedges now.
