The S.drive is one of many "budget performance summer tires" on the market, summer tires with okay dry grip, very good grip in rain, and reasonably long treadlife. They are designed for folks who are willing to sacrifice some performance (compared with top-of-the-line tires) in order to save a few bucks on purchase price. If you want the best performance for your NSX, get a top-of-the-line tire like the Goodyear F1 GS-D3, Bridgestone Potenza RE050A Pole Position, etc; tires like the S.drive don't perform as well. And if you do want to get cheaper tires with lower performance, check prices; the Kumho SPT and Fuzion ZRi offer performance virtually identical with the S.drive, at prices that are lower in most sizes.[/quote]
1. The RE050As are stock on my AMG CL55; they lasted 5k miles in the rear with uneven wear. I replaced them with the new Yoko Advan s4s with better results here in NH.
2. My 2003 NSX came with the Fusions. They are not acceptable and the new Yoko S.Drives are much better in every handling dimension. These tires are just not in the same category. I respectfully disagree; the Tire Rack evaluations and tests seem to confirm my choice. They not be A category tires but they are much more advanced than the Fusions.
3. The issue is what do we do in NE where we can go from an 80 degree temp to a 50 degree temp on the same day or if we drive into the mountains or Lakes region. Max Summer tires, esp. of the older generation, just do not work in NE as well as they do in Southern CA or Florida. All the major manufacturers are offering "all-season" versions of their max performance summer tires.
4. All my friends who track (eg Loudon) their street cars of any high performance brand have a separate set of dedicated tires for the track and another set/style for street use.
5. As far as Nexens go I had a set of their H rated SUV tires on my used MB G500 "Panzer" and they were cut by stones on a dirt road in New Brunswick. I was stranded for several hours in the boonies while folks in their Fords sedans just drove by. I would be very leery of buying this brand. They are cheap tires.... I replaced them with Yoko A/S which are recommended by the manufacturer (and TR) for sensible off road use. They handle well on road also.
6. If you press a good Acura dealer they recommend the European alignment setup for road use that does not seem to compromise perfomance - it's an Autobahn setup - for sensible road/track driving with lessened tire wear.
I respect the Tire Rack expertise and those on NSXprime. These are good discussions.
