Rear Tire Fit Issue

Here is my situation, I have a 1972 Nova non-tubbed running a MT drag slick jegs part#672-3056R which is a 29.5 x 9.0-15 with 4.88 rear gears. The driver side rubs a little on the inside and the passenger side rubs a little on the outside. My questions is: will a p275/60r15 drag radial tire (28 x 11.5-15) fit? I plan on running two classes at the track so I need dot drag tires.
thanks for the help
