Have a 2006 RRS SC with 79K miles. Bought new and take care of it like a baby. Have had no significant problems other than I am needing to buy my FOURTH set of tires!!! Got about 32K on the stock Contis. Got about 29K on the second set of Contis. Decided to to go with Michelin Diamaris for the third set and will not get much more than 20K miles. I rotate every 6000-7000 miles and don't do any off roading with the vehicle. Does anyone have any suggestions for a good street tire that doesn't end up costing an arm and a leg and gets better than 20K?? Any suggestions will be appreciated.
