Tires are 26 x 10.5 x 16 et street, they are mounted on a diamond racing steel wheel. I used to use these wheels back in the day for an 2004 cobra. The first pass I launched at 3000 it ran 1.821 60' and a 7.790 at 91.39 mph. The last pass I went from idle and ran 1.772 60' and a 7.699 at 91.55 mph.
