What would be a good size bias ply that is equal in size to a 325-50-15?
28x13.5x15 is the comparable bias ply.
Thanks!

Section width on the M/T 325/50 is 13.1" Section width on the M/T 28x13.5 is 13.2" Section width on the M/T 28x12.5 is 12.6" Section width on the Hoosier QTP 28x13.5 is 12.9"
Bias ply is going to flex more since the side wall is softer, so any of the 13.5's may rub. Sounds like you should go with the 12.5" tire to gain a little clearance. How much room do you have to the front of the wheel well? Bias ply will grow in height as well at speed. If you have 1/2 inch or more I wouldn't worry one bit.

I have at least a 1/2 inch of room so should be good. How are the hoosiers in comparison to the m/t`s?
The QTP bits better than the M/T but it also have a shorter life span... ran them both at drag week in the past

So it seems that a bias ply is the way to go and just pick one that fits best for my application. I am going to compare the various tires sizes and pick one that will fit the best. Again I appreciate the feedback guys!
the side wall on the bias tire can take shock better (not as stiff)
