Quote: They won't last as long with a spool, it scrubs the tire and the side wall doesn't give like a slick.
I second that, after swapping to a spool my last set of M/T's got finished off pretty quick. I run regular street tires then swap when I drive to the track now. I will say I've got quite a few street miles and passes out of my Hoosier pro drag radials, I even bought them used at a X275 race
