I will say I used to run Hoosier QTP bias tires on my 63 and its a street car so I run radials up front. Now it is an auto but I decided to try the Hoosier 30 x 9 radial slicks and do I love them. I drive on the street on them all the time also and the one big difference is the car just drives better and goes straight without any wondering on the top end that it did some when the bias QTP tires were on it. And the radials always hook good for me. Granted its only a 10.70 car but its so much nicer to drive with radials on all 4 corners. Good luck with yours as I have heard most stick guys do use bias tires. Ron
