the MT Pro's are DOT but not for "street use" Kind of a goofy statement, they were designed for the 275 and 10.5 class. I drove them 52 miles raced and drove home w/o issues. My main track is/was 22 miles away no issues. I have them at 28-30 when driving and drop them to 17-18 for racing. It's not good to go to low w/ a radial, they will "cup"
