JD has to put all the values into the World Commands central processing unit so it can grind out the answers and encrypt them for JD's eyes only.

So we all just know to ask JD when we have a questions about wheels/tires :D


Seems like some of the winning racers run square setups 245 front and rear, or bigger from what I have been reading but they may have modified the suspension as
well to get it all to fit in the larger sizes.

Bigger in back is not always better for traction and handling apparently.
