So Im about to hit 11K miles and i want/need new tires but i want to get a little of a softer tire that will last longer then 10-12K miles but still be a semi good performance tire and go with a little more width, my RFP1's are 18x8.5.... any suggestions.....?

Just go to tirerack and check off Max perf summer and select anything with a wear rating of 220+. Stockers are one category below that and have only a 180 rating.
