I want to run an experiment to see which physical factors most help 60’ times. I have a hypothesis that tire diameter plays a much bigger role than people think. Basically I want to get a lot of data from you guys, and then run a multiple linear regression (sorry Ima geek) to see statistically what factors are really important. I will post the results when I get enough data. So here is what I need… • 60’ time • Tire dimensions (e.g., 275/40/17) • axle ratio (e.g, 4.10, 3.55) • peak rwtq • tire type (street, dot DR, slick) Thanks for the help
