Hi, bought NS2 R for 133 Gordini. Will keep PS2 195 40 17 as NS 2R may wear out fast. I believe the profile for 195 40 17 is too low and encourages bumpy ride and road noise. Not expectiing too much comfort from NS2R but went for looks and they are good on track (being used by BMW on track for their road series).
