Any radial racers or small tire guys?

I run 295/65/15 Mickey drag radials and the only problem I have had with them is tire shake. On a no prep track, if it spins at the hit - one pedal and it hooks back up. But on a heavily prepped surface it sometimes shakes so hard it breaks the 9 inch. I have lost the rearview mirror off the windshield twice as well. My car hates any pressure below 18psi. I tried them once at 25psi right off the street and it dead hooked.
