Re: How do big tires stress axles?
All these answers seem to make sense. I wonder what the formula is for figuring this out. I've seen lots of advice on this board (and elsewhere) indicating that 35s' will break a model 30, but 33's are marginally okay. I guess the real answer is that it depends on the width and weight of the tires as well as the height. A 33/14.50 tire on steel rims might put more stress on the axle shaft than a 35/10.50 on aluminum rims. There must be a math formula for this. Does anybody have that "automath" book. Maybe it has the answer.
