If rollout differs. I was told and found true.It is easier to shrink the larger one than it is to stretch. Not say both is bad idea. To shrink, Drop ppressure tp almost nohting. Heat the tire.I use blow heater and rotate avery few minutes. Let sit. Then pump up tp pressure and measure. On a fuel car we drop pressure if car is going to be siting for long period. We also do not pump tires to stupid pressures for loading either since it will stretch rollout some.  All of that said it is just another approach and may or may not work better for you.

Having some background in circle track racing, I'd think 11/16" would certainly tend to turn the car of you're trying to go straight.....especially with a really narrow rearend like a dragster.
