Rick,
As a replacement of my P4000's, I purchased the Pirelli Cinturato P7 All Season Plus SL's from Tire Rack ($113/each) and had them dropped shipped to my local tire guy who installed them. I am VERY pleased with the tire performance and lack of road noise since it is a convertible. It is the 225/60R-16 and it has that rounded look you were looking for. If you compete in Champions class, make sure your spare is a Pirelli before ordering. My understanding (someone correct me if I am wrong here) is that your spare must be the same make as your tires. If you need some pictures, just let me know and I will send them to you.
FYI....Pirelli was giving a $60 Visa card with the purchase of 4 tires when I got mine a few months back....they may be still running the promotion.
Best Wishes...Rick W.
