Yes they are Hoosier radial slicks that are 30 x 9. I would run drag radials but no one makes them in that size and I like the 30" tall tire. I also like the 9" wide as they fit great in my stock wheelwells and don't rub on any turns. I have been driving on these radial slicks since I put this eng in 8 years ago. Twice Police came up to me and both times they just talked about how they liked my car. One used to race and he even said to me when I was leaving the Farm Store I stopped at to be careful driving on them. They actually handle nice on the street since I run radials up front. I love having radials on all 4 corners of my car because it drives so nice on them. I have even been caught in the rain twice on them and just drove home nice and easy with no problems. Ron
