Holley LS Fest - Tire size question? pls help

Hi i was wondering bout my tire size i have 295/45/17 m/t radials and i was wondering if would be able to run i was looking at some of the classes and it says 275 only did not know if it means for all or not. This is going to be my first time at holly ls fest dont now how all the rules apply if someone can explain to me that would be awesome becuse i dont now what drag class to select and i would like to get my tickets ordered.

I could be wrong but this is the link to the 275 info that im familiar with. not sure if the 275 class will be the same here...

I just need to know for sure if I can run at any off the drag classes with size off tiers I have don't have the extra cash right not to throw at new tiers. So if any one knows for sure pls let me know thanks!!
