I have read all 150+ replies to the original question and there are some great ideas. The combo thing could work if the rules were written right and enforced properly you could increase car counts. But as Leader's Edge states there is not a shortage of pavement cars out there, but only the ones chasing points can afford the tire bills. To be honest I doubt many can afford the tire bills but swallow it just to be able to compete.

Having built and raced dirt and pavement sprintcars for Dynamite Race Cars the only major difference between dirt and pavement is the tire bill. The cost between putting together a dirt or pavement car is minimal (few thousand ie, shocks, brake system etc.). When we ran with HOSS/AVSS it was pretty easy to set up a tire rotation system to maximize the use of your tires without losing an advantage. They would stamp the RR tire as you go out for qualifying and that is the tire you had to run for the feature. You could do this for the RF,LF also and leave the LR open for stagger purposes. When we ran with USAC we picked up our pace every time out due to chassis adjustments but everyone else was too but also picking up even more time due to putting new rubber on evry time out. If you did the stamping you would only need 2-3 tires a night instead of 2-3 sets a night thus greatly reducing the cost to compete.
