The MT 28x7.5 is about 0.6" wider overall and 2" taller than what you currently have on the car. Do you have 1-3/8" to 1-1/2" clearance around the perimeter of your tire at rest and full lock? Do you have 3/4" or more clearance to the fender lip on the outside? Key places to check will be as the tire sweeps past the front edge of the fender, the rear where the bolt is, the frame at the inside back as you turn all the way out and your fender brace. Easiest way will be with no torsion bar so you can check full extension and full compression.
Sorry I can't answer your question directly.
