295x65x15?

I need to buy tires to narrow my rear end I'm I'm wondering if anyone has used these in a non backhalf car?

There a little taller than the 29x10.50x15 but I dont wanna order tires that hit my package tray or just plain wont fit no matter how much I cut...

Hoosier DOT Drag Radial Tires 17316DR2

Car is 71 dart.

I see that the description says not for highway use... even tho they are DOT?

If I'm gonna get rolled for illegal tires should I just run slicks?
