Hoosier Quick Time D.O.T

Ive been thinking pretty serious about getting a set of Hoosier Quick Time D.O.T. Tires for my 68 dart with 6" wide cragers. Car is only a show car but I REALLY LOVE the look of a fatter tire. My question is what kind of milleage do you guys guess i'd get outta these tires if I drive easy without any burnouts (tire life NOT mpg)? and yes they will fit, i have seen many darts with that combo and my offset with factory fenders and spring location, if not i'll return em. And I know their bias, so ill give up ride quality for looks! I need the 26" tall tires for my 3.91s, would love to find this size in a radial but the 15"wheel swap is too much $$ for me right now!


thanks guys and heres a link to the specs on the tire I want.
