Re: Drag Radials
It seems that a 10" rim with a radial tire is probably the most popular combination being used right now. I understand the logic behind that, with increased air pressure and decreased rolling resistance, etc., but what about the somewhat old school approach of using a narrower rim and a tire designed to grow a significant amount, allowing the final drive ratio to raise as wheel speed increases. I seem to remember a time when some of the tire manufacturers offered "high-growth" sportsman tires. The variable ratio effect would seem to me to be a real advantage if utilized properly ( i.e. steeper gearing) or has the wide rim/radial tire combination actually been proven to be that much better?

The reason I brought this up is that at one time there was a theory that wide tires on a narrower rim would provide more "bite" at launch due to the flattening of the tire providing all 9 inches at the hit, also the tire growth on the other end. The other theory was that a wide rim with a narrower tire planted the tire for a longer period as the car accelerated from the line. Just wanted to hear which wheel everyone was using with the radial. |

Are you running the #18209.... 30.0/9.0R-15 Hoosier, radial? If so, I would start at 21 psi and work my way down (no less than 18 psi). What do you run for a 60' time? |

Worth noting is that a radial is more sensitive to track conditions. A bias ply will be more consistent and predictable under marginal conditions. But a radial is faster. So one has to figure out his/her priorities/needs.
