2019 summer race.... Jadaharabi vs 318willrun

Well I got the new 15 by 7 cop wheels and now I'm deciding exactly what tire to put on the back? I'm leaning towards the Mickey Thompson 275 60 15 but they're saying I need a 7 and 1/2 inch rim? I know they got the nittos out there also but I'm not sure exactly what to put on there..?? What's say ye drag race consensus?? Remember I ride with a E- body width rear axle. The tires stick out a little bit but my rear ends up high enough not to hit them. I like them because they're 28 like my Hoosier slicks were. And they barely fit in the fender walls but they still didn't touch the front fender well since I put that half inch spacer in.
