I replaced the run flats on my SC430 (2003) with Conti Exremes. I now have 35,000 on those tires. The ride has been great, so much better than the OEM tires.
I'm now replacing the Conti's with Michelin Pilot Sports (cost more than the Conti) because Costco does not offer the Conti's.
I got the Conti from Tire Rack and had a local mechanic install them (installation is hard, due to the tire pressure sensors, I guess).
Are those the Michelin - Pilot® Sport PS2™ for
$318.99 . How are they working? Did Costco put a new sensor on? I thought those were Michellin's version of a Run Flat tire. I called Costco yesterday and they have a Michellin Run flat tire for 318. Thanks. MIS
