I'll side with Dave on this one, although you need more than a high school
physics book. Tractor rollovers are more complex events than they seem.
Larger diameter front wheels can make a big difference in reducing impacts
that can initiate rollovers. As noted, the length of the moment arm also
reduces impacts.

As I've explained to airline pilots before, weights, balances, and angles
are only part of the story.

You might want to refer back to your HS Physics book before you  
discredit this particular "old wives tale!"
