Need to replace my rear tires soon (12,500 miles). My dilemma is that the Sportcontact 2's are no longer produced in Porsche N-spec designation. Continental still makes the SC2's in 295/30/ZR19 but without the N-spec "blessing". Does this really matter? My front tires are like new and I'd hate to incur the expense of replacing all four right now. At next go around I'll go for the preferred Michelins or Pirelli's but for now I'd like to just buy rears. Any thoughts? Car is driven 100% for pleasure and only in good weather.
