Select tires for the front of your narrow body Pantera which are 24" to 25" OD, 225 to 245 cross-section.
It is a common mistake to try and set the front tires too far outward, closer to the fender lip. What happens is you'll end up with a tire that rubs the fender lip in high speed corners.
225mm front tire: 6mm offset - 7.5 inch wheel (20mm recessed)
235mm front tire: 11mm offset - 8 inch wheel (20mm recessed)
245mm front tire: 16mm offset - 8.5 inch wheel (20mm recessed)
8" wide Campy clone wheels (Pantera East) are designed with 23mm offset, 9" wide Kinesis wheels are designed with 25mm offset.
Select tires for the rear of your narrow body Pantera which are 26" to 27" OD. My personal preference is a tire in the range of 275mm to 295mm cross-section. The exact cross-section depends upon the tire's availability and its outside diameter.
Others prefer tires in the range of 315mm to 335mm cross-section. Neither choice is wrong, each person knows what's best for them, or will learn from experience. The outside diameter of 315mm tires are an issue for me. 6018 had a set of them when I purchased it, I felt they were way too small for the fender opening.
