Especially with lower power cars and small diameter tires. (i.e. little to no wheel spin potential)


Please explain. I would think smaller diamater tire would have an easer time loosing traction/spin because
A. contact patch is smaller
B. Smaller tire equals more rpm effectavly giving more torque at the wheels at a gives engine speed.(if that makes anysense)


A. Diameter and width are not the same thing.
B. Which would make an ATX launch better due to getting "free" stall rpm and an MTX require a slip from a lower rpm point.

Yes the higher effective final drive ratio would make it easier to spin the tires. Hence my second statement.

However if you don't spin the tires significantly the short times will improve. That doesn't mean the entire run is better on shorter tire though. My statement was that it is "easier" to generate quicker 60' times on shorter tires.
