Hi, I`ve been thing about selling my RS-A2-tires and buy tires with better handling and lower rolling resistance. I see that a lot of SUV-tires have specs close to TMS. For instance I found the ContiEcoContact 5 with 235\55\R19. It has won numerous prices and no other tire that I know of can match it`s low rolling resistance. It also costs a bit less than for instance CSC5 and GY F1 AS2. The revs pr minute goes down from 729 to 692, is this too much?
