Question about wheel track...

For those that run a 190mm chassis and 200mm body, how do you space out the wheel/tire combo? Do you run the 6mm offset wheels on all fours and put the 26mm tires on the fronts (would that even work)? Or do you just leave everything tucked in, inside the body?

The USVTA rules seem pretty particular about only running 26mm tires up front and 31mm tires in the rear.
