Had a question for those who have experience running both of these . I am currently running the Blackwall bias ply Firestones with the pie crust style outer tread on my 1932 Ford roadster . I daily drive the car frequently .I have never had a chance to run the dirt track style Firestone’s . I know they look completely different from one another , but my question is does one have better drivability than the other ? Or being that they are both bias play will there be little difference and mainly just difference in appearance ?
