17 The 10-year-old drag radials (left) had to go. We needed safer, stickier skins to hook the Nova into the 10s. The old tires still offered decent traction, but were dry-rotted badly from being outside in the elements for years before we bought the Nova. Our new (325/50R-15), Nitto NT555R drag radials were the same size as the old BFGs we were replacing. The good thing about the Nittos is they are legit street tires, unlike some other drag radials, which are not recommended for street use.
