here's an idea that would save more money than just tires.
No hotlaps.
Unload the cars and race them.
Less wear on the motors.
Less wear on the chassis and components.
Less methanol.
No hotels bills since time at the racetrack would be 4 hours or less.
and No testing.

Now my motor will last all season or 2 (or 3). I will only need to buy 3 new tires per race maximum. $50 for methanol per race.

This will probably be as popular as a turd in a punch bowl, but hey- its the internet, everyone has an opinion:34;
