The Nitto Extreme 555's are generally ok on a DD as an everyday tire. Good wear for me..!! However, If you have any appreciable rwhp, don't count on any traction from them !! I've had the 555's.... 255/45/18 up front and 285/40/18 in the rear for quite a while now and without any problems. Also, i've tried the 305 555R`s (drag radials) in the rear for about a week and they were ok for traction when heated, but were down right scary in the heavy rain. Off they came......!!
