As HarryLeach said, there are a lot of factors in determining what compound is good for any particular carpet track. On my very high bite track 24's would give unreal traction but wouldn't last very long. 28's get about three meets before they are relegated to a practice tire or visit the bin. If we had an OPEN tire policy than 24-28's might be the choice for very competitive drivers that are willing to buy tires more frequently.
Low bite carpet tracks would need lower 'degree' tire as they require the extra grip.
For your standard med-high bite carpet track, 30-32's will be good and last much longer.
My track opted for 32's as a Spec Tire for TC 17.5 & GT2 21.5 because we have loads of traction & 32's will last many meets. Makes for more affordable racing and helps to level the playing field out so it's more about driving skill over who has the best of everything.
