I think those are almost 30" tall or so. I have a 68 Fasbatck and run a 28x10.5 Pro Bracket Radial and there is very little room for a taller tire. I ran a bias slick for a little bit and it actually rubbed the front of the fender opening at high speed, not much but just enough to make a shiny spot. The radial doesn't grow so there is no trouble there anymore. I don't think a 30" tire would clear without either really pulling it in to the middle of the car or doing some body work.
