Front tire size vs. ET in a Stocker....

Would like to see the calculations for future reference. Being a numbers type of guy I'm always curious. I don't see a way to calculate this since you have at least 3 unknown variables in each instance. The velocity when the 60' timer starts and the velocity when the 60' timer is tripped are 2 of them, and difference in rate of accel due to the changes is a 3rd. True, the geometry can give difference in the 60' distance which is not really exactly 60' and varies with the tire height but that alone does not translate to a time difference.
Also, no one has mentioned the possibility of the car lifting out of the beam and not rolling out. If that happens then the delta of the 60' distance is not able to be calculated and the other variables still exist.

With so many variables I think the only way to know is to test it as tgriffith stated.

Normal disclaimer: I could be wrong and my opinion can be swayed.
