Hey guys, what the fastest have you went on reg hard radial tires(no dr, soft compound or bias ply). A track close to me is having a hard tires class for Toy for Tots in 2 weeks. Ran my gn other day best so far is a 1.80 60ft at 7.65--95mph not too bad for hard tires. Also this is on grand am tires 255x60x15
