I just changed my Dunlap runflats out for Pirelli P Zero Nero All Seasons NRF. I found this tire to suit me best for my driving here in LA. So far the ride has been quiet, smooth, very responsive and overall has changed my attitude about my car. I hated the runflats! Go to a good tire dealer for help and do look at serveral tire dealer websites for end user ratings. I checked Tire Rack and America's Tire. Both have very good information to help you find the right tire. As far as the spare I decided to use Auto Club until futher notice. By the way, Costco insist that you have a spare.
