Inadequate for the HP & TQ the engine makes. I understand the class requires nothing larger than a 9x30. But then again, that rule has been around since 500HP was a killer engine. These engines are somewhere around double. Three tenths is left in that combo and it's there to be found. The reality is, it doesn't need to be found. Not today anyways!

Not sure how you figure that tire is inadequate. We run on a 275/60-15 DOT drag radial tire and run 1.15 60's consistently, 1.12 best. I have not had any problems with that tire handling 1080 hp at 2925 lbs. My tire is 10" tread, but less sidewall at only 28" tall.

Granted, apples to oranges comparing a street legal DOT to a radial slick, but very similar constructed tires. What one gives up in width it picks up in rollout.
