That excuse is B.S. The 10.5 tire is slower by approx .05. That rule was put in many years ago when IHRA had the AA/S class before NHRA ever thought about it and the points race tracks were not what some would call first rate for safety reasons. The tracks are MUCh better today so its a wash. The 9 inch radial will always be quicker unless they are worn out. The extra capacity pan allows someone to run fast WITHOUT trying to run with 3 QTs of oil in a stock pan. Better engine life. How many NHRA guys see zero oil pressure after the finish line when doing this trick ! It kind of helps keep the rods inside the engine where they belong.
