Slicks rubbing

[Mayhem]

Just put new 33x18.5 Hoosiers on. Same size in street tires worked fine. But these are rubbing in turns on the outside inner well. Doesn't look like air pressure will resolve it either. Short of putting it up on the lift and removing the wheels and hammering the inner wells, what options can I do?

Someone said to get a closet dowel rod or a wooden bat and roll it around the well with the tire as a guide and that may massage it enough. I don't think so.

Would it be safe to hammer on the inner wells? Really don't want to cut and weld them. This car is full tubbed already. Just needs like 1/2" clearance, When driving in turns, it allows the tire to flex enough to rub, only on the outer edge. More air psi would make it fatter, less would make it softer and flex more. Any ideas?

It has also created heat and bubbles the paint. Damage is done there, but I don't want to ruin the slicks too.
