I NEED THE 411 ON THOSE WHO HAVE 18'S (7.5F/8R) ON THERE RIDE, ON WHAT SIZE TIRES YOU ARE RUNNING? I WAS TOLD BY A RELIABLE SOURCE, BUT I AM JUST SEEING WHAT OTHERS ARE RUNNINGI WAS TOLD TO RUN A 225/40 F AND A 255/35 R. THE FRONT SEEMS TO BE COOL, BUT I AM UNSURE OF THE REARS. . IF IT HELPS I AM LOOKING AT THE SO3 TIRES. THANKS.
